Vascular Plants

Sources used to compile this list include Hulten's Flora of Alaska and Neighboring Territories, Hall's Native Plants of Southeast Alaska, Muller's A Preliminary Checklist of the Vascular Plants in Southeastern Alaska. Additionally, when available, range maps in the Flora of North America were consulted. Choices of scientific name primarily follow the Flora of North America, though there are occasional deviations. I also relied on the USDA PLANTS Database for names. Disagreements were typically decided in favor of the Flora of North America.

Clubmosses, Ferns and Allies (Lycopodiophyta, Pteridophyta)

Isoëtaceae (Quillwort: 4 species)

Scientific Name	Common Name	Summary
Isoëtes echinospora	Spiny-spore Quillwort	Expected to occur throughout the region (see FNA range map), but apparently few collections, including at least two on Baranof Island and one on Prince of Wales Island.
Isoëtes maritima	Maritime Quillwort	Expected on islands and the northern gulf coast. Apparently only a few collections including from Shelter Island, Prince of Wales Island, Revillagigedo Island, and the Yakutat Forelands.
Isoëtes occidentalis	Western Quillwort	Primary range seems to be well south of the region (FNA Map), though there are apparently a few scattered reports in south coastal Alaska. In Southeast Alaska this species has so far only been reported from Baranof Island.
Isoëtes x truncata	Quillwort Hybrid	Hybrids of Western Quillwort (Isoëtes occidentalis) with Maritime Quillwort (Isoëtes maritima) or Spiny-spore Quillwort (Isoëtes echinospora) have been given this name and may be found in the region.

Selaginellaceae (Lesser-clubmoss: 4 species)

Scientific Name	Common Name	Summary
Selaginella selaginoides	Low Lesser-clubmoss	In Southeast Alaska, this species is expected on islands and the northern mainland (FNA range map). Apparently few collections, but the e-flora BC collections map indicates at least one collection from the southern mainland, as well as other reports from the BC coastal mainland not far south of the border. (Given the somewhat odd distribution, perhaps this is a candidate species to check for evidence of genetic isolation in Southeast Alaska glacial refugia.)
Selaginella sibirica	Siberian Spikemoss	May only occur in the extreme northeast part of the region where it has been collected outside of Haines on Takhin Ridge. It has also been found just north of the border at White Pass.
Selaginella standleyi	Standley's Spike-moss	Expected to occur in the far northeast part of the region (FNA range map). Apparently few, if any, collections from Southeast Alaska.
Selaginella wallacei	Wallace's Spikemoss	This species reaches the northern limits of its range near the southern border. So far only one record from the region on Revillagigedo Island (herbarium record of collection). Also photographic record from Red Bluff Bay may be this species.

Lycopodiaceae (Clubmoss: 11 species)

Scientific Name	Common Name	Summary
Diphasiastrum alpinum	Alpine Clubmoss	Small, trailing clubmoss with flattened, 4-ranked leaves infrequently found in high elevation forest and tundra and occasionally at lower elevations. In the region, it has been collected more often in the mountains from the lower part of Lynn Canal north.
Diphasiastrum complanatum	Ground Cedar	Apparently few collections in the region, the distribution of this species seems to favor areas more influenced by continental climates.
Diphasiastrum sitchense	Alaskan Clubmoss	Trailing club moss with rounded stems found in high elevation forest and tundra. Collections are primarily from the northern half of the region on mountains near the Gulf of Alaska, though it is unclear whether this represents the actual distribution accurately.
Huperzia continentalis	Alpine Fir-moss	Fairly common larger clubmoss of (sub)alpine tundra where it is the only Huperzia typically found. Formerly considered a part of H. selago. A few scattered collections from across much of the region.
Huperzia miyoshiana	Pacific Fir-moss	A few collections in ARCTOS scattered across the region.
Huperzia occidentalis	Western Fir-moss	A single collection in ARCTOS from Port Alexander.
Lycopodiella inundata	Bog Clubmoss	Known from south of Fredrick Sound (including the southern half of Baranof Island), though FNA Range map implies it is to be expeted throughout much of the region. In 2009 a collection was made on Chichagof Island. Can be abundant where found, but reports have been infrequent, with only a few collections from the region.
Lycopodium clavatum	Running Clubmoss	Found mostly in open areas from low elevation to subalpine. This species may reach the northern extent of its regular range in the region (FNA map), though it is probably fairly common throughout. Collections have been made throughout the region (though see L. lagopus).
Lycopodium dendroideum	Tree Clubmoss	Expected throughout the region (FNA range map), collections of this species are mostly from about Frederick Sound south (including mid-Baranof Island).
Lycopodium lagopus	One-cone Clubmoss	Expected from the far northern mainland part of the region (FNA range map). As of late 2013, only one collection currently in Arctos (from the Juneau Ice Field) - perhaps some older ones are still labeled L. clavatus?
Spinulum annotinum	Stiff Clubmoss	Common throughout the region with many collections. Found in forests and muskegs from sea level to subalpine.

Ophioglossaceae (Adder’s Tongue: 16 species)

Scientific Name	Common Name	Summary
Botrychium alaskense	Alaska Grapefern	Expected in to occur in the region. At least one collection from a limestone ridge on central mainland. This species was described in 2002 (?) and is known to occur in Alaska, British Columbia, and Yukon Territories.
Botrychium ascendens	Triangle-lobe Moonwort	Described in 1986 and known in our region from beaches of the Yakutat Forelands, this species has a scattered distribution across North America and may be present elsewhere in the region.
Botrychium campestre	Slender Moonwort	Apparently rare throughout much of its range, this species has been found near Yakutat.
Botrychium hesperium	Western Moonwort	May occur in the far northern mountains along the border with Canada (see map on the pdf linked in references).
Botrychium lanceolatum	Lance-leaved Grapefern	Expected throughout the region, but so far primarily collected only on the northern mainland between Yakutat and Haines, with one collection (the only report from lower elevations?) from Prince of Wales. Also found near Juneau on Baranof Island (photo records in iNaturalist)
Botrychium lunaria	Moonwort	Expected to occur throughout the region, it appears most collections are from on or adjacent to the northern mainland, with a collection from Lisanski Strait and another from Coronation Island being exceptions.
Botrychium minganense	Mingan Moonwort	Expected throughout the region, collections in Southeast Alaska so far have been from (sandy) beach meadows and limestone areas away from the beach. Locations in include, northern Chichagof Island, the northern mainland from Lynn Canal west to Yakutat, a single collection from Prince of Wales, and two additional collections from alpine locations on the southern mainland.
Botrychium montanum	Mountain Moonwort	Apparently found near the northwestern-most edge of the region. This species has also been found to the south in BC, and may occur elsewhere in the region, though its small size may make it easily to overlook.
Botrychium neolunaria	Common Moonwort	Expected throughout the region - though apparently no collections? (need to check with Mary Stensvold), the name this ended up being could be Moosewort (Botrychium tunux)
Botrychium pedunculosum	Stalked Moonwort	Not currently known from Southeast Alaska, the nearest report of this species appears to be from British Columbia a ways inland from Prince Rupert. There is also a population that has been found well to the west on the Alaska Peninsula.
Botrychium pinnatum	Northwestern Moonwort	Expected throughout the region, there are apparently currently very few collections of this species from Southeast Alaska (mostly out of Haines), with one from the southern mainland. This species has been considered at subspecies of B. boreale and may be labeled as such in herbarium records.
Botrychium spathulatum	Spatulate Moonwort	Collected from stabilized maritime sand dunes on Kruzof Island this species may be expected to occur elsewhere in the region. One additional collection from Icy Bay at the boundary of the region. It is quite similar in appearance to Triangle-lobe Moonwort (Botrychium ascendens) (see pdf linked below for a table of characters used to differentiate the two).
Botrychium tunux	Moosewort	This recently described species is known from the Yakutat area. Previously considered part of B. neolunaria (though B. neolunaria is not yet formally described - so perhaps this should be B. lunaria?)
Botrychium yaaxudakeit	Giant Moonwort	Described in 2002 from collections made at sandy beaches near Yakutat. Also collected from Glacier Bay. Plants of this species had formerly been considered B. neolunaria.
Botrypus virginianus	Rattlesnake Fern	Scattered collections from Coronation Island and northern Prince of Wales north, though coastal collections to the south suggest this species could be expected to occur infrequently throughout much of the region.
Sceptridium multifidum	Leathery Grapefern	Expected throughout the region, though apparently only four collections from the region - one near Skagway, one near Yakutat, and two from northern Chichagof (though there are reports from Haida Gwaii and other locations in coastal BC).

Equisetaceae (Horsetails: 10 species)

Scientific Name	Common Name	Summary
Equisetum arvense	Common Horsetail	Almost certainly common throughout the region in open or disturbed areas from low elevation to the subalpine. Extensive areas of the region have few or no collections of this species (perhaps because of its ubiquity).
Equisetum fluviatile	Swamp Horsetail	Expected throughout the region. Probably more widespread than collections (scattered, mostly on the mainland) may indicate. May be abundant where it grows in shallow waters or marshy habitats.
Equisetum hyemale	Common Scouring-rush	Expected throughout the region, though apparently very few collections (note: Arctos has E. hiemale for some records; and many that are not georeferenced that may include SE Alaska material).
Equisetum palustre	Marsh Horsetail	Expected throughout the region (FNA Range map), this species has apparently only been collected from a few scattered locations on the mainland in Southeast Alaska (pending review of many non-georeferenced records in Arctos).
Equisetum pratense	Meadow Horsetail	Expected throughout the region (FNA map), but apparently very few collections (pending review of non-georeferenced arctos records). Has been reported from Coronation Island and Chichagof Island.
Equisetum scirpoides	Dwarf Scouringrush	Expected to occur on the northern mainland and outer islands (FNA map). Apparently few, if any, collections from the region (pending review of non-georeferenced records in Arctos)
Equisetum sylvaticum	Woodland horsetail	Expected on northern mainland and southern outer islands (FNA map). Few collections from the region (pending review of many non-georeferenced arctos records).
Equisetum telmateia	Giant Horsetail	Expected on the outer islands (FNA map), it is unclear on what basis this inclusion was made. Reported from Haida Gwaii south of the region, but no reports of this species in Southeast Alaska have yet been discovered.
Equisetum variegatum	Variegated Scouring-rush	Found throughout with several collections made from throughout the region. Scattered in occurrence but sometimes abundant where it is found.
Equisetum x litorale	Horsetail Hybrid	Expected throughout the region (FNA map) it is unclear how often this hybrid between E. arvense and E. fluviatile occurs.

Hymenophyllaceae (Filmy Fern: 1 species)

Scientific Name	Common Name	Summary
Hymenophyllum wrightii	Filmy Fern	A very small fern only documented as a gametophyte in Southeast Alaska. H. wrightii gametophytes resemble unbranched leafy liverworts. Expected in the southern half of the region (FNA map), there are few collections - likely due to ease with which they would be overlooked where they grow on decaying wood in a variety of low elevation forest types.

Aspleniaceae (Spleenworts: 3 species)

Scientific Name	Common Name	Summary
Asplenium adulterinum	Adulterated Spleenwort	Officially known only from Vancouver Island, the FNA account of this hybrid between Maidenhair Spleenwort (Asplenium trichomanes) and Asplenium trichomanes-ramosum suggests it could be expected elsewhere. A plant with the (apparently diagnostic, key-wise) character of partially brown rachis was photographed (but not collected) at Red Bluff Bay.
Asplenium trichomanes	Maidenhair Spleenwort	Small evergreen fern with ovate pinnae which is expected to occur, but seems to be less common than A. viride. Two subspecies indicated in FNA, with ssp. trichomanes expected in the southern half of the region (FNA map) on acidic substrates, while ssp. quadrivalens (which occurs on limestone) not thought to occur in the region (FNA map). However, most collections from Southeast Alaska have been made from limestone, so further investigation may be warranted.
Asplenium viride	Green Spleenwort	Expected throughout much of the region. Collections seem to primarily be from outer islands and the northern mainland. Seems to be scattered, though can be locally fairly common, especially in some limestone areas and also on the ultramafic bluffs at Red Bluff Bay.

Athyriaceae (Lady Ferns: 2 species)

Scientific Name	Common Name	Summary
Athyrium alpestre	Alpine Lady Fern	Expected through at least the southern half of the region (FNA map), this species has apparently only been collected in Southeast Alaska a few times, including from northern Chichagof Island, Coronation Island, the north central mainland, Baranof Island, and Revillagigedo Island.
Athyrium filix-femina	Common Lady Fern	Common large deciduous fern of forest openings and open forest. Occasionally forming nearly pure stands. Expected to be common throughout the region, across most of Southeast Alaska, there just a few collections of this species in Arctos that have been geo-referenced.

Blechnaceae (Chain Ferns: 1 species)

Scientific Name	Common Name	Summary
Struthiopteris spicant	Deer Fern	Fairly Common evergreen rosette forming fern found in forests and occasionally in shady open areas. Expected throughout the region, though there are fewer collections in the Arctos database from the northern areas. Whether this is indicative of lesser (more scattered) occurrence, or an artifact of collection effort is unclear.

Cystopteridaceae ( 4 species)

Scientific Name	Common Name	Summary
Cystopteris fragilis	Fragile Fern	Fairly Common fern typically found on wet cliffs. Quite a few collections of this species have been made from sites scattered throughout the region.
Cystopteris montana	Mountain Bladder Fern	Expected throughout the region (FNA map). Collections from the southern outer islands, Chichagof Island, one on Admiralty Island, and the mainland north of Haines. Seems like it may be associated with calcareous geology.
Gymnocarpium disjunctum	Pacific Oakfern	Common deciduous fern found in most productive forests, often in large colonies in riparian forest. Expected throughout the region, apparently only a few collections from both the south and north, but none in the central part (seems likely there are older collections still labeled G. dryopteris). Hybrids with G. dryopteris should be expected.
Gymnocarpium dryopteris	Western Oakfern	Expected and probably common throughout the region, some collections labeled as this species may be G. disjunctum. Hybrids with G. disjunctum should be expected.

Dennstaedtiaceae (Bracken Ferns: 1 species)

Scientific Name	Common Name	Summary
Pteridium aquilinum	Bracken Fern	Expected throughout the region (FNA map) where it reaches the northern extent of its range. There are scattered collections from much of the area (except the Northern Gulf Coast), though most have not been geo-referenced (and so do not show up on the e-Flora BC map). This species is apparently most often found at the transition between muskeg and coniferous forest. This species appears to reach the northern extent of its range within the region.

Dryopteridaceae (Wood Ferns: 14 species)

Scientific Name	Common Name	Summary
Dryopteris carthusiana	Spinulose Woodfern	A single collection from Paradise Valley on the Juneau Icefield, this species has also been collected just across the border from Haines as well as at Bennett Lake on the other side of White Pass. It is reported from Haida Gwaii as well as other coastal areas of BC just south of our region.
Dryopteris expansa	Spreading Wood Fern	Medium to large sized fern common in moderately to higly productive forests. Occasionally fronds remain green through winter.
Dryopteris fragrans	Fragrant shield fern	Expected on the northern mainland mountains, but apparently few, if any, collections from Southeast Alaska.
Polystichum andersonii	Anderson's Holly Fern	Expected throughout the region (FNA map) collections from the region have primarily been made near Juneau, Ketchikan, or Sitka, with apparently only a handful from other locations, including Yakobi Island, Glacier Bay, north Chichagof Island and Coronation Island.
Polystichum braunii	Braun's Holly Fern	Expected throughout the region (FNA map), there are quite a few collections from locations scattered throughout. FNA notes that hybrids with P. lonchitis are known from Southeast Alaska.
Polystichum kruckebergii	Kruckeberg's Hollyfern	Found on ultramafic rock outcrops which are limited in the region. Locations were this species has been collected include Red Bluff Bay, the Cleveland Peninsula, and Annette Island.
Polystichum kwakiutlii		Known only from the type specimen collected not far south of the border in coastal BC. FNA notes: "This species is presumed to be one of the diploid progenitors of P . andersonii . It should be sought among the boreal 2-pinnate polystichums, from which it can be distinguished by the presence of bulblets. Polystichum kwakiutlii differs from P . andersonii in its completely divided pinnae and entire indusia."
Polystichum lonchitis	Northern Holly Fern	Expected throughout the region (FNA map), there appear to be a fair number of collections from locations scattered throughout much of Southeast Alaska.
Polystichum munitum	Western Sword Fern	Expected in the southern half of the region (FNA map), collections of this species have been made as far north as the southern end of Baranof Island.
Polystichum setigerum	Alaska Holly Fern	Expected throughout the region (FNA map), this species seems to be primarily be a Northwest Coast endemic (with a disjunct occurrence on Attu Island), ranging only from coastal Southern BC through Southeast Alaska. Collections have been made from scattered locations throughout the region.
Woodsia alpina	Alpine Cliff Fern	Expected on far northern mainland as well as the northern outer islands (FNA map), this species has apparently only been collected a handful of times in Southeast Alaska, and perhaps only once since the 1930s.
Woodsia glabella	Smooth Cliff Fern	Expected to be more inland, but apparently rare in the region - reported from Admiralty Island, the Ketchikan area, and Misty Fjords. (The latter two reported in Hall 2010, but there do not appear to be collection records in Arctos for those locations.)
Woodsia ilvensis	Rusty Woodsia	Expected on the northern mainland (FNA map), there only a few collectioned georeferenced in Arctos. These include some from Mendenhall Glacier, one from Glacier Bay and one from Chichagof Island. Additional records from Southeast Alaska could be in the set of non-georeferenced collections.
Woodsia scopulina	Mountain Cliff Fern	Expected throughout the region (FNA map), apparently few collections from Southeast Alaska (only one in Arctos, linked below).

Polypodiaceae (Polypody Ferns: 3 species)

Scientific Name	Common Name	Summary
Polypodium glycyrrhiza	Licorice Fern	Common fern of low elevations. Grows as epiphyte and on open rocks and cliffs. Expected throughout the region (FNA map), there are apparently only a few (geo-referenced) collections from Southeast Alaska. (Further searches in Arctos may reveal additional collections without coordinates.)
Polypodium hesperium	Western Polypody	Not currently known from the region, but present on Haida Gwaii just to the south. There is a collection record from Prince William South as well, so this species could be expected to occur in Southeast Alaska.
Polypodium sibiricum	Siberian Polypody	A single 2015 collection from Haines labeled as this species is the only report of this species, which appears to be more typically found in the interior in Alaska.

Pteridaceae (Maidenhair Ferns: 4 species)

Scientific Name	Common Name	Summary
Adiantum aleuticum	Maidenhair Fern	Perennial fern with fan-shaped delicate fronds common on wet cliffs and forested wet areas, especially on slopes and rocky areas. Expected throughout the region, except possibly the far northern parts (FNA map), this species has been collected (in Arctos as A. pedatum) widely throughout the region south of Juneau and Icy Strait, though most collections appear to be from islands.
Cryptogramma acrostichoides	American Rockbrake	Expected throughout the region (FNA map). Collections have been made from scattered locations throughout. Hybrids with C. sitchensis may occur.
Cryptogramma sitchensis	Sitka Rockbrake	Expected throughout the region (FNA map), most collections in the region appear to be from the northern half. (Whether this is due to differences in frequency or an artifact of sampling effort is unclear.) Appears to reach the southern extent of its distribution in North America in the region.
Cryptogramma stelleri	Fragile Rockbrake	Expected throughout the region on sheltered calcareous cliff crevices and rock ledges (FNA map), there are apparently very few collections in the region. One from northern Prince of Wales Island was described as being found "in narrow crevice of limestone, near base of cliff, well-shaded"

Thelypteridaceae (Marsh Ferns: 2 species)

Scientific Name	Common Name	Summary
Phegopteris connectilis	Northern Beech Fern	Expected (and probably common) throughout the region (FNA map), there are only a few collections, mostly from the southern part of the area and around Haines. Checking the non-georeferenced collections in Arctos may reveal additional collections as well.
Thelypteris quelpaertensis	Queen's-veil Maiden Fern	Expected throughout the region (FNA map), the georeferenced collections are mostly from the southern part of Southeast Alaska, with one from Lisianski Strait. Review of non-georeferenced collections in Arctos may reveal additional collections.

Conifers (Pinophyta)

Cupressaceae (Cyprus: 3 species)

Scientific Name	Common Name	Summary
Chamaecyparis nootkatensis	Yellow Cedar	Expected throughout the region, this species is locally abundant in some areas, but has also been subject to Yellow Cedar Decline over the past 100+ years, resulting in extensive cedar death. This species is the subject of on-going study and the effects of climate change.
Juniperus communis	Common Juniper	An easily over-looked evergreen shrub. The needle-shaped leaves are blue-green during the growing season, often brown or grey in the winter. In some locations, this species may be very common, but more often scattered. Expected throughout the region, collections are scattered throughout much, with some significant gaps, most prominently West Chichagof and the Northern Gulf Coast. (Pending review of non-georeferenced collections in Arctos)
Thuja plicata	Western Red Cedar	Expected throughout the southern half of the region (excepting Baranof Island).

Pinaceae (Pine: 8 species)

Scientific Name	Common Name	Summary
Abies amabilis	Pacific Silver Fir	Known from the extreme southeastern part of the region. A handful of collections from Revillagigedo Island and the mainland south of there.
Abies lasiocarpa	Subalpine Fir	Reported (and rumored) from scattered (sometimes isolated) locations throughout much of the region, collections of this species come from three primary areas, the coast mountains east of Lynn Canal, the coast mountains near Hyder, southern outer islands - Dall and Prince of Wales.
Picea glauca	White Spruce	It is unclear whether this species occurs in pure form in the region. Trees of hybrid origin of this species and P. sitchensis are known from northern river valleys and could reach the border along other transboundary rivers.
Picea sitchensis	Sitka Spruce	Very common from sea level to the Montane Forest. Occassionally found in stunted form in subalpine and alpine habitats. Also may be found in a stunted form on small islets and wet meadows or fens. Attains largest size in well drained valley bottoms. Scattered collections from throughout the full length of the region but with many gaps - perhaps because the species is so common, there was little need to collect it.
Pinus contorta	Shore Pine	var. contorta expected throughout the region, with var. latifolia expected to occur in some locations where it has moved down transboundary rivers, especially in the north. Scattered collections from throughout much of the region, though much less on the outer islands.
Pseudotsuga menziesii	Douglas Fir	Planted in some locations as a landscaping/ornamental tree.
Tsuga heterophylla	Western Hemlock	Abundant in the region as the dominant species in many forested areas. There are collections from much of the region, but with significant gaps, perhaps due to this tree's ubiquity.
Tsuga mertensiana	Mountain Hemlock	This coniferous tree often the dominant tree in montane forests near treeline. It is the most typical clump forming tree in subalpine parkland that also is commonly found growing in krummholz at exposed locations in the mountains. In muskegs and mixed scrubby stands at lower elevations it is still found, though less commonly. Although probably common throughout the region in its preferred habitats, there are only about 25 collections of this species in Arctos (with the biggest gap being from north of Sitka up along the Northern Gulf Coast - where perhaps it is less common? Also, with the exception of the single collection at Sitka, there are not really any collections from the central part of the region. )

Taxaceae (Yew: 1 species)

Scientific Name	Common Name	Summary
Taxus brevifolia	Pacific Yew	Only a few collections (6 in arctos), all from the extreme southern part of the region, including Prince of Wales, Dog Island, and Revillagigedo Island. Collection notes indicate it can be common to abundant where it is found.

Dicots (Magnoliopsida)

Aceraceae (Maple: 1 species)

Scientific Name	Common Name	Summary
Acer glabrum	Douglas Maple	One of the few species of deciduous trees found in southeastern Alaska. Douglas Maple can be locally common (Shaman Island near Douglas), but for the most part maple tends to be unusual to rare. Widely collected from north to south, there are no collections from the outer coast. (Does it prefer a somewhat less than hypermaritime climate, or is it just poorly documented?)

Adoxaceae ( 3 species)

Scientific Name	Common Name	Summary
Adoxa moschatellina	Musk root	No collections in arctos from Southeast Alaska (though the species is widespread throughout much of the rest of the state). A single collection from Juneau (in 1952) is included on the e-Flora BC map. There is also a collection from Mile 83 of the Haines highway just across the border.
Sambucus racemosa	Red Elderberry	Common shrub with some weedy habits. Found mostly in open and disturbed habitats. Many collections from throughout the region.
Viburnum edule	Highbush Cranberry	Quite a few collections from throughout much of the region. No collections from Baranof Island nor Admiralty Island, though this species presumably occurs there.

Amaranthaceae (Amaranth: 2 species)

Scientific Name	Common Name	Summary
Amaranthus albus	Prostrate Pigweed	Muller included it as being introduced in the Juneau area, but there are no collection records in Arctos, nor on the e-Flora BC map. Species is included in AKEPIC, but no records indicated for Southeast Alaska. Perhaps this species is not really established?
Amaranthus retroflexus	Redroot Pigweed	Reported from the Sitka area (both on the Muller checklist, as well as on AKEPIC info sheet), though there are no collections in Arctos, nor any reflected on the e-flora BC maps, and AKEPIC does not have it occurring in recent surveys for non-native species, so it seems likely this species is not established.

Apiaceae (Carrot: 14 species)

Scientific Name	Common Name	Summary
Angelica genuflexa	Kneeling Angelica	Fairly common herbaceous plant with pinnately compound genuflecting leaves and umbrella-like clusters of flowers found in wet areas (non-bog?), including stream sides, lake margins, and beach meadows. Collections widespread throughout the region, though with some significant gaps, including southern outer islands, the central islands and mainland, northern inner islands, and Glacier Bay.
Angelica lucida	Seacoast Angelica	Fairly common plant of open areas including beach and subalpine meadows. Poorly collected through much of the region (though presumed to be at least fairly common throughout). Collections appear to be limited to the extreme south and from Juneau north along the mainland (including Yakutat).
Cicuta douglasii	Western Water Hemlock	Apparently scattered throughout the region. Few collection records from the central part (none away from the Stikine River).
Cnidium cnidiifolium	Jakutsk Snowparsley	Single collection record in arctos appears to be Pacific Hemlock-parsley (Conioselinum gmelinii) that has been mis-named in the database.
Conioselinum gmelinii	Pacific Hemlock-parsley	Most common along the upper beaches and meadows. Can also be found at higher elevations even up to sub-alpine meadows. Many collections from throughout the region (mostly under synonym C. pacificum).
Glehnia littoralis	Pacific Silvertop	Although considered to occur on sandy beaches throughout southeast, it has so far been collected only at Yakutat, with reports from Kruzof Island. (Limited to outer coast?)
Heracleum maximum	Cow Parsnip	Very common large herb with hairy stems, ternately compound leaves and tall stalks with umbelliferous inflorescences. Found from sea level to the subalpine in open (mostly well-drained) areas and forest margins. Scattered collections from throughout the region. Probably under collected relative to its distribution and abundance.
Ligusticum calderi	Calder's Lovage	Endemic to coastal area between northern Vancouver Island and extreme southern Southeast Alaska. Only a hand full of collections from the region, all from Dall Island or southern Prince of Wales Island.
Ligusticum scoticum	Beach Lovage	Fairly common but restricted to rocky seashores above all but the highest of fall and winter tides. Expected throughout the region in this habitat. Scattered collections throughout much of the region.
Oenanthe sarmentosa	Pacific Water-parsley	Probably throughout the region in suitable wet habitat, but only a few scattered collections apart from southern inner islands (Revillagigedo Island south) and mainland.
Osmorhiza berteroi	Mountain Sweet-cicely	Probably throughout, but few collections in much of the region. Most collections are from Juneau north, with a handful of scattered collections to the south. (Less common than Purple Sweet-cicely (Osmorhiza purpurea)?)
Osmorhiza depauperata	Blunt-fruit Sweet-cicely	Collected only from the northern mainland near border with Canada. Overall distribution appears to be primarily continental, and it should perhaps not be expected throughout much of the more maritime parts of the region.
Osmorhiza purpurea	Purple Sweet-cicely	One of the first spring flowers, this plant is fairly common in open forested areas, and abundant in riparian alder forest. Widely collected throughout much of the region.
Pastinaca sativa	Wild Parsnip	No collections from the region in arctos are indicated on e-flora BC maps. Also not indicated for the region in AKEPIC. Introduced species would not seem to be established in the region.

Apocynaceae ( 1 species)

Scientific Name	Common Name	Summary
Apocynum androsaemifolium	Spreading Dogbane	No collections from Southeast Alaska. In northern part of its range it appears to be restricted to more continental climates, so if it occurs, it is probably only at the northeastern margins of the region.

Araliaceae (Ginseng: 1 species)

Scientific Name	Common Name	Summary
Oplopanax horridus	Devil's Club	Common robust shrub with abundant thorn on stems and underside of large maple-shaped leaves. Most abundant in steep areas or alluvial forests. From sea level to subalpine. Collections from throughout much of the region.

Asteraceae (Asters: 107 species)

Scientific Name	Common Name	Summary
Achillea millefolium	Yarrow	Perennial aromatic herb with finely dissected leaves and small white compound flowers commonly found in meadows, cliffs and well drained disturbed locations from sea level to subalpine. Collections from throughout the region.
Achillea ptarmica	Sneezeweed	Apparently no more than a couple of collections from the region. One in arctos (from an old garden site at False Island on Chichagof Island). In addition, AKEPIC includes reports from Gustavus, Juneau, and the Stikine River (or Zarembo, georeferenced location and description do not match).
Agoseris aurantiaca	Mountain Dandelion	Collected from Glacier Bay and the northern mainland (including upper Lynn Canal and the St. Elias mountains near Yakutat. Overall range appears to be mainly in continental mountains.
Agoseris glauca	Pale Agoseris	Several collections from the northeastern mainland. A single collection in arctos from just across the border near Hyder. Overall range seems to be primarily in the mountains away from the coast.
Ambrosia chamissonis	Silver Burreed	Only three widely separated collections, the first (in 1993) from Yakutat at the far north end of the region, the second (in 2003) from the middle of the region on Kruzof Island, and the last near the southern-most extreme of the region on Kanagunut Island (in 2005).
Anaphalis margaritacea	Pearly Everlasting	A fairly common gray green herb with round, white clusters of small flowers. Most frequently found on road sides, also found along gravel bars. Collections spanning the region, but with significant gaps (e.g., no Baranof Island or Southern Island collection records in Arctos).
Antennaria alpina	Alpine Pussy-toes	Collections primarily from northern mainland, but also a couple from southern mainland. One from Prince of Wales Island another from Admiralty Island are the only island collections.
Antennaria media	Dark Pussytoes	Perhaps ultimately best considered within Alpine Pussy-toes (Antennaria alpina), kept separate for now following FNA. Appears to be considered synonymous with A. alpina in Arctos records. It is unclear how many collections of this species/form have been made in Southeast Alaska.
Antennaria monocephala	One-flowered Pussy-toes	Collection records mostly from mainland mountains north of Juneau/Glacier Bay. One island collection from the north end of Admiralty Island.
Antennaria pulcherrima	Showy pussy-toes	Overall range appears to be more continental. In the region there are a pair of collections from Gustavus and another two from Haines.
Antennaria rosea	Rosy Pussy-toes	Collections in the region primarily from the northern mainland, with one collection from Baranof Island (Glacier Lake).
Antennaria umbrinella	Umber Pussytoes	Status of this species is unclear, although considered to occur throughout by Muller, most records in Arctos that show up when searching for this species are labeled Antennaria rosea ssp pulvinata. FNA does not list this as a synonym of A. umbrinella (or vice versa), and does not indicate this species as occurring in Alaska. Records shown on e-flora BC map indicate a more interior distribution, and if this species does occur in the region, it's probably along the margins.
Anthemis cotula	Mayweed	No collections in Arctos, AKEPIC reports only three observations from Skagway (2009), near Kook Lake on Chichagof Island (2005), and Rowan Bay (2004).
Anthemis tinctoria	Yellow Chamomile	Apparently no collections or reports from the region.
Arctanthemum arcticum	Arctic Daisy	Apparently reaches the southern extent of its range on the eastern Pacific coast in the region. Collections from the outer coast of Southeast Alaska are limited to Yakutat area and a single collection along the north side of Icy Strait. A record from Freshwater Bay on eastern side of Chichagof Island the only one on an outer island. There are scattered collections from the Stikine River mouth north to Skagway on the mainland and inner islands.
Arnica angustifolia	Narrow leaf arnica	Only a couple of collections from the Haines vicinity. Seems likely to be limited to the northern continental margins of the region.
Arnica chamissonis	Leafy Arnica	Apparently only four collections from the region in ARCTOS and/or e-Flora BC. North Prince of Wales Island, Mitkof Island, Haines, and Dry Bay.
Arnica cordifolia	Heart-leaved Arnica	Apparently only collection from Southeast Alaska was made near Haines. Overall range appears to be more continental, so probably limited to margins of region.
Arnica griscomii	Snow Arnica	Southeast Alaska appears to be at the southwestern limits of the range of this species. Only a single collection from the region in ARCTOS, from Mitkof Island. A second collection from near Haines is in a different herbarium. Mitkof Island records appears to be something of an outlier (both in terms of range and expected habitat), and this species is probably only to be expected along the north eastern margins of the region.
Arnica lanceolata	Clasping Arnica	Fairly common perennial herb with yellow daisy-like flowers found in riparian areas, meadows and along roadsides. Taxonomic changes make tracking collections a little difficult. In ARCTOS, most seem to be linked with A. lanceolata, while in e-Flora BC, more are associated strictly with A. lanceolata ssp. prima. In ARCTOS, collections from throughout much of the region, though more weighted towards the outer coast. Gaps in the extreme south, and in the central inner islands and mainland, but probably occurs throughout.
Arnica latifolia	Broad-leaf Arnica	Probably somewhat common herb with yellow daisy-like flowers and 2-4 pairs of opposite leaves. Collections from throughout, though more in the northeastern part of the region. Only three collections from outer islands, and none from the central mainland.
Arnica lessingii	Nodding Arnica	Several collections, mostly from the northern part of the region. A single collection from northern Prince of Wales Island, and another from Dall Island are the only collections in ARCTOS south of Chichagof Island (though it has been reported from Baranof Island, as well).
Arnica lonchophylla	Longleaf arnica	Apparently no collections from close to the region. Probably does not occur.
Arnica mollis	Hairy Arnica	Single collection from Shakes Lake in 1993. Even assuming collection is correctly assigned, it is not clear whether this species is established in the region, as Southeast Alaska would appear to be near the northwestern-most limits of the regular range (though there are a handful of collections from further west in Alaska). However, other collections from northwestern British Columbia suggest the possibility that this species could occur at the northern margins of the region.
Arnica ovata	Sticky Leaf Arnica	A single collection from a Juneau Icefield nunatak in 1982 is the only one for the region. It was reported to be common in the location it was collected.
Artemisia alaskana	Siberian wormwood	Nearest collections appear to be near the British Columbia/Yukon border north of Haines. Given primary range (northern/continental), this species, if it occurs at all in Southeast Alaska, probably only occurs at the very northern edges.
Artemisia campestris	Field sagewort	Status of this species is unclear. There are no collections from the region indicated on the maps for either ARCTOS or eflora-BC (nor any even particularly close). However, there quite a few collections in ARCTOS without georeferencing, some of which may be from Southeast Alaska. Both Muller and Hall note this species as occurring, however perhaps there have been taxonomic changes.
Artemisia dracunculus	Tarragon	Collected along the Stikine River at a spot georeferenced as just on the Canadian side of the border. Given overall range, it is likely to occur only at margins of region, if at all.
Artemisia frigida	Prarie Sagewort	No collections from the region, but one collection just across the border along the Stikine River. If this species occurs in the region, it is probably only at the margins.
Artemisia furcata	Forked Wormwood	Single collection from the Alsek River is the only record from the region. Overall more northerly distribution suggests this species is likely to be rare and/or absent in most of Southeast Alaska.
Artemisia norvegica	Boreal Sagebrush	Common plant of meadows near treeline. Also found on gravel bars of larger rivers. Several collections from both the southern part of the region as well as the northern mainland. Only a couple of collections from the northern islands.
Artemisia tilesii	Tilesius' wormwood	Known primarily from the northern mainland with collections from the upper end of Lynn Canal as well as the St. Elias Mountains and Harlequin Lake outside of Yakutat. Additional collections from just across the border on the Taku and Stikine Rivers, suggest it could occur in those areas as well. A single 2009 collection from near Hoonah is the only island record. The overall range of this species is more northern, and Southeast Alaska appears to be at the southern edge of its range.
Bidens frondosa	Devil's beggartick	Weedy annual native to North America Although reported in Muller and indicated for the region on the FNA distribution map, there are no collections of this species in ARCTOS nor any reports on the e-Flora BC map. The nearest are from the vicinity of Vancouver, BC, well to the south. AKEPIC also does not show any reports for the region.
Canadanthus modestus	Giant Mountain Aster	Abundance unclear. Seems like it may be possibly confused with Sub-alpine Daisy (Erigeron peregrinus) or Douglas Aster (Symphyotrichum subspicatum) Collections primarily from the northern (inside) mainland. A single collection from the Stikine River is the only one on the mainland south of Juneau. A collection from Game Creek on Chichagof Island, and another from near Craig on Prince of Wales Island are the only island records. Southeast Alaska is at the northern end of the overall range (a couple collections in southern Yukon are the only north of the region). In western Canada and the Pacific Northwest, there appears to be only limited collections from near the coast, so perhaps much of Southeast Alaska is marginal climate-wise for this species?
Centaurea montana	Perennial Cornflower	Common ornamental in many communities, may have started to go feral in some locations, but does not yet seem to be naturalized in the region. Collections in ARCTOS from Hyder and Juneau. Considered potentially invasive, AKEPIC data includes reports from other communities in the region as well.
Centaurea stoebe	Spotted Knapweed	Introduced and potentially invasive species. AKEPIC indicates reports of this species from several communities throughout the region.
Cirsium arvense	Canada Thistle	Several collections in Arctos, with many additional reports AKEPIC from communities throughout the region. Also a few reports from remote areas, mostly where logging activity has occurred (in particular, roads).
Cirsium edule	Edible thistle	Only collection in ARCTOS is apparently from the British Columbia side of the border near Hyder. Southern Southeast Alaska would seem to be at the very northern edge of the range of this species.
Cirsium foliosum	Leafy thistle, Elk thistle	No confirmed occurrence of this species in Alaska, the collections/reports indicated on e-Flora BC maps are all from from the Rocky Mountains well inland, so it seems unlikely this species occurs in the region.
Cirsium vulgare	Bull Thistle	Intorduced species considered a noxious weed. Has been reported as far north as Haines, but most reports are from the southern part of the region.
Conyza canadensis	Canadian Horseweed	Single 1982 collection from logging camp site is the only record for the region. Seems unlikely to be established.
Cotula coronopifolia	Common Brassbuttons	Only two collections in Arctos, both from Mitkof Island in the same bay. A third collection is indicated in the AKEPIC fact sheet for this species.
Crepis capillaris	Smooth Hawksbeard	Collections in Arctos from Skagway and Wrangel as well as two remote sites with human disturbance (logging or mining). Apparently no other documented reports.
Crepis elegans	Elegant Hawksbeard	No collections in ARCTOS from the region. The e-flora BC map indicates some reports/collections from the Haines triangle of BC. It appears the primary range of this species is more interior and/or northern.
Crepis nana	Dwarf Alpine Hawksbeard	No collections from the region in Arctos or indicated in e-flora BC, though the latter has a 1956 collection from mile 75 of Haines highway, just across the border. Overall distribution suggests if this species occurs in the region, it is most in the mountains of the northern border.
Crepis tectorum	Narrowleaf Hawksbeard	Introduced species. Has been reported (see AKEPIC data) in many locations throughout much of the region, especially on Prince of Wales and around Haines and Skagway.
Erigeron acris	Bitter Fleabane	Several collections from the northern mainland (in the vicinity of Gustavus and Haines/Skagway). Two additional collections from Hyder area. A single 2007 collection from Kosciusko Island is the only island record.
Erigeron compositus	Cut-leaved daisy	1979 collection from the Haines Highway is the only one from region in Arctos, with an additional one from just across the border near Atlin Lake.
Erigeron denalii	Denali fleabane	No collections of this species from Southeast Alaska in ARCTOS, though one collection said to be from Yukon appears to be georeferenced just on the Alaska side of the border between Yakutat Bay and Icy Bay.
Erigeron glacialis	Subalpine Fleabane	Treated as a subspecies of Sub-alpine Daisy (Erigeron peregrinus) in e-Flora BC, FNA considers a species. No collection records of this taxa in the state in ARCTOS, though a plant found in Sitka was initially identified as this species. https://archive.org/details/biostor-159535
Erigeron humilis	Alpine Fleabane	Perennial herb with purplish, hairy foliage and stems single white daisy-like flowers. Higher elevations, limestone outcrops, and recently deglaciated areas. Scattered collections, more from the northern part of the region. Not collected from Chichagof or Baranof Islands, though it has been reported from both.
Erigeron lonchophyllus	Spear-leaf fleabane	No collections in ARCTOS from Southeast Alaska, nor any indication of such from e-Flora BC, where nearest is from mile 86 of Haines highway.
Erigeron peregrinus	Sub-alpine Daisy	Pale to dark purple daisy common in meadows and rich fens from sea level to just above treeline. Many collections from throughout much of the region. What gaps are presumed to be from lack of collecting rather than non-occurrence. https://archive.org/details/biostor-159535
Erigeron purpuratus	Purple fleabane	No collections of this species from Southeast Alaska in ARCTOS. FNA lists this species as only occurring in Alaska and the Yukon. Status for Southeast Alaska is unclear, but it seems likely to occur only at the very margins, if at all. There has been some disagreement on the status of E. purpuratus. Some souces list it as a synonym of E. pallens, however G. L. Nesom and D. F. Murray (2004) support the seperation of the taxa.
Erigeron uniflorus	Northern Daisy	Not known from Southeast Alaska, it has been reported from BC near the Haines Highway not far from the border. The overall range of this species is more northern and continental. If this species does occur in the region, it is almost certainly limited to alpine regions of the mountains near the border.
Eurybia sibirica	Arctic aster	e-flora BC map indicates two ARCTOS collections from mountains along the north gulf coast. ARCTOS nomenclature appears to maybe consider this species synonymous with Sub-alpine Daisy (Erigeron peregrinus), since those also come up in the search for Eurybia sibirica.
Gnaphalium uliginosum	Slender Cudweed	Scattered collections or reports from throughout the region in towns or at old log transfer facilities. Appears that it is probably rare (with only a single data report in AKEPIC), so it is unclear to what extent this species is established in the region. AKEPIC also has G. palustre, but calls both species "low cudweed". There are several additional reports of this latter species in the data there, but no collections in ARCTOS, no reports anywhere close to Southeast Alaska on e-Flora BC maps, and FNA does not include this species for Alaska. May need some follow up.
Hieracium albiflorum	White-flowered Hawkweed	Only collections appear to be from upper Lynn Canal, upper Glacier Bay, and near Hyder. Occurrence apart from areas near the border is unclear, perhaps this far north it favors more continental influenced climates.
Hieracium aurantiacum	Orange Hawkweed	Introduced species with tendencies toward invasiveness. Collections in ARCTOS (from as early as 1960s) were made primarily along the road systems of several different communities in the region. AKEPIC data indicates reports widely distributed reports, especially in southern Southeast Alaska, mainly (but not exclusively) along roads or in other areas of human disturbance.
Hieracium caespitosum	Meadow Hawkweed	No collections of this species in ARCTOS, but reports from several communities (Juneau, Kake, Petersburg, Wrangell, Ketchikan) and on Prince of Wales in the AKEPIC database.
Hieracium lachenalii	Common Hawkweed	Several reports (in AKEPIC database) of this species from along the road system of Wrangell Island, as well as Zarembo Island. Apparently no reports from elsewhere in the region.
Hieracium pilosella	Mouse-ear Hawkweed	No collections in ARCTOS. Known from Prince of Wales Island where there is a single 2006 report (with plants pulled) included in AKEPIC database.
Hieracium triste	Wooly Hawkweed	Yellow ray-flowered composite with hairy stems and leaves common in open areas just above treeline. Occasionally found in meadows at lower elevations. Likely to be present throughout the region in appropriate habitat. Collections in ARCTOS from throughout much of the region, but with some gaps. Many from the Haines/Skagway area. FNA has lumped H. gracile with this species.
Hieracium umbellatum	Narrowleaf Hawkweed	No collections in ARCTOS. Reports included in AKEPIC database from several communities or other areas of human use, including Gustavus, Sitka, Petersbug, Wrangell, and Prince of Wales Island.
Hypochaeris radicata	Hairy Cat's Ears	An introduced species with the potential to be highly invasive. Collections from several communities in the region. Many reports in the AKEPIC database from the southern portion of the region, with fewer from communities in the north.
Lactuca biennis	Tall Blue Lettuce	Appears to be uncommon (or at least infrequently collected). Collected from only three locations all along Lynn Canal. Two were in upper beach meadow areas. Unclear how widespread this species is in the region.
Lapsana communis	Common Nipplewort	Two collections in ARCTOS, one from Ketchikan (1979) and two from Sitka (first in 1996). Many reports in AKEPIC database, mostly from communities, but also other areas of human activity (roads, logging camps, etc.). Seems to be more common in the southern part of the region.
Leucanthemum vulgare	Ox-eye Daisy	Introduced species that is common around towns. A few collections in ARCTOS, primarily from Sitka, Ketchikan, Haines, Skagway and Juneau. Many reports in the AKEPIC database from most communities, and also some other areas of human disturbance.
Madia glomerata	Tarweed	Collections from Haines and Skagway. Native to North America, the nearest other collections in e-Flora BC are a small number south and well inland of Southeast Alaska, with most collections being restricted to near the Canadian border with the lower-48. AKEPIC has it included on the non-native species list for Alaska (with a report from Haines).
Matricaria discoidea	Pineapple Weed	Although considered introduced by many sources, the FNA account indicates this species actually originates in northwestern North America and has spread from there. AKEPIC has it listed as an introduced species in the state. Only a few collections in ARCTOS (some under M. matricarioides). Many observations from throughout the region in the AKEPIC database. Occurrence away from areas of human disturbance is unclear.
Microseris borealis	Northern Microseris	A west coast endemic. Some patterns of occurrence unclear. For example, common in many Kruzof Island muskegs, but absent from muskegs along the Sitka road system, even though distance is not great. Well collected from southern outer islands, with a few more from southern inner islands. Two old collections from the Sitka area, and one more from the northern mainland along Icy Strait are the only others from the region (there are more from coastal areas north and west of the region). Probably under collected in part, but perhaps also prefers more hyper maritime climate?
Mycelis muralis	Wall-lettuce	A 2004 collection from the vicinity of Ketchikan is all that is in ARCTOS. Many reports of this species from the southern half of the region (not including Baranof Island) in the AKEPIC database.
Packera cymbalaria	Dwarf Arctic Ragwort	Despite occurring throughout much of the rest of Alaska (both interior, and more coastal areas at Kodiak Island and the Alaska Penninsula, in Southeast Alaska, this species is only known from the southern outer islands, where it's been collected on Prince of Wales (1979) and Coronation Island (1959). Perhaps this somewhat disjunct occurrence in southern Southeast Alaska (and Haida Gwaii) represents a refugial population that was separated from the main group during the last ice age?
Packera indecora	Elegant Groundsel	Five collections in ARCTOS, all from the northern part of the region. Two at Gustavus and two on the Yakutat Forelands. A 2012 collection at Hoonah is the only island record.
Packera ogotorukensis	Ogotoruk Creek Ragwort	Two collections from Southeast Alaska (Dall Island and Prince of Wales Island) are disjunct from the primary range of this species which is more northerly (including much of mainland Alaska). Is this species absent from much of Southeast Alaska, Rare, or overlooked and/or subject to misidentification?
Packera pauciflora	Rayless Alpine Butterweed	Based on ARCTOS records, the first collections of this species in the region appear to be two made in 1991 near Yakutat. Since that time there has been a third collection near Yakutat and an additional one from Glacier Bay. General range of these species seems to be more continental.
Packera paupercula	Balsam Groundsel	Two collections from the region in ARCTOS, one on the Chilkat Peninsula and another at Gustavus. (There are two additional collections from Prince of Wales Island that were previously identified as this species, but have reevaluated and given different names.) Overall distribution in the region is unclear.
Packera streptanthifolia	Rocky Mountain Groundsel	No collections in ARCTOS from Southeast Alaska. Collections there and on the e-flora BC maps suggest this species is primarily found on the landward side of the coastal mountains, and as such, is perhaps unlikely to be found in Southeast Alaska.
Packera subnuda	Queen Charlotte Butterweed	Collected from as far north as northern Prince of Wales and Coronation Island, it is also found on other southern outer islands. Endemic to area between northern end of Vancouver Island and southern Southeast Alaska.
Petasites frigidus	Arctic Sweet Coltsfoot	Presumed to occur throughout the region. Collections in ARCTOS are primarily from the mainland (but spanning south to north), with only a single collection from Coronation Island that is not on the mainland or a nearby island. Whether this is indicative of a preference for more continental influence resulting in a less common occurrence on outer islands is not clear.
Prenanthes alata	Western Rattlesnake-root	Fairly common plant of open areas. Found from sea level to subalpine meadows. Collections in ARCTOS from throughout (except Glacier Bay), including most of the major islands.
Saussurea americana	American Saw-wort	Only nine scattered collections in ARCTOS, with all but two from the year 2000 or later. Collected from Prince of Wales Island, Baranof Island, and Chichagof Island, as well as mainland collections near Juneau and the mountains between Lynn Canal and Glacier Bay. Only a few reports from British Columbia indicated on e-flora BC maps. It's unclear whether this species has been overlooked, or is simply uncommon (with more deliberate efforts to collect it when found in recent years).
Senecio jacobaea	Tansy Ragwort	May be spreading in the region, or perhaps had been overlooked. Most reports in AKEPIC from disturbed areas in southern Southeast Alaska. Additional collections in ARCTOS from Kruzof Island and Admiralty Island.
Senecio lugens	Black-tipped Ragwort	ARCTOS collections from the region are all from Prince of Wales Island, Dall Island, or Kosciusko Island. It appears that most (maybe all) of the collections are from limestone/karst areas. Overall the distribution of this species is more inland. There are some collections in the e-Flora BC maps from just over the border in the northern part of the region.
Senecio pseudoarnica	Seaside Ragwort	Collections in ARCTOS mostly from the northern outer part of the region, with a pair at Yakutat, two more on northern Chichagof Island, another two in Sitka Sound, and the only other one from down on Revillagigedo Island. Southeast Alaska is near the southern extent of this species range on the west coast of North America. There are collections from northern Haida Gwaii.
Senecio sheldonensis	Mt. Sheldon Groundsel	Not reported from the region - there is an observation from near the Haines highway on the BC side of the border.
Senecio triangularis	Arrow-leaf Ragwort	Presumably throughout the region. Collections in ARCTOS span the region, though some of the major islands do not have any associated collections.
Senecio viscosus	Sticky Ragwort	Based on reports in AKEPIC, this introduced species appears to be relatively common near Skagway, where it has been for some time (there is an ARCTOS collection from 1968). Additionally, single reports from Haines (in 2007), and Sitka (2008).
Senecio vulgaris	Common Groundsel	There a few collections of this introduced species in ARCTOS. Data in AKEPIC indicates it is established in several communities throughout much of the region.
Solidago lepida	Canada Goldenrod	Presumably present throughout, there are collections in ARCTOS from most of the region (though some are under S. canadensis and not S. lepida), but not the extreme south.
Solidago multiradiata	Northern Goldenrod	Expected to occur throughout. Collections in ARCTOS spanning most of the region with notable gaps including Admiralty Island and the southern inside Islands and mainland.
Solidago simplex	Sticky Goldenrod	No collections in ARCTOS or on e-Flora BC maps from Southeast Alaska. There are records from the Alsek River and near the Haines Highway not far from the border, so this species may occur at the margins in Southeast Alaska.
Sonchus arvensis	Field Sowthistle	This introduced species has been found in several communities throughout Southeast Alaska. It has also been found on northern Admiralty Island (at what are probably popular recreation sites for Juneau residents).
Sonchus asper	Spiny Sowthistle	Introduced species so far known from the southern part of the region. Collections in ARCTOS from Sitka and Wrangell, additional reports in AKEPIC from Kake, several locations across Prince of Wales Island, Ketchikan, and Metlakatla (though not from Wrangell or Sitka).
Sonchus oleraceus	Common Sowthistle	Introduced species reported (AKEPIC database) from a few communities in the southern half of the region including Sitka, Wrangell, Kake, Ketchikan, and Metlakatla.
Symphyotrichum boreale	Northern bog aster	The primary range of this species appears to be east of the coastal mountains. There is a single collection in ARCTOS identified as this species from Prince of Wales Island. There is a 2015 collection from Haines in the PNW Herbaria Consortium database.
Symphyotrichum foliaceum	Alpine Leafybract Aster	The Flora of North America treatments indicates that Symphyotrichum foliaceum var. foliaceum occurs in Southeast Alaska. There no mapped collections in ARCTOS identified (though some collections that are called Douglas Aster (Symphyotrichum subspicatum) are included under a search for S. foliaceum). The FNA treatment of S. subspicatum indicates that species "passes into" this one in Southeast Alaska.
Symphyotrichum subspicatum	Douglas Aster	Collections from throughout the region (mostly under Aster subspicatus). FNA indicates this species "passes into" Alpine Leafybract Aster (Symphyotrichum foliaceum) in Southeast Alaska.
Tanacetum bipinnatum	Common Tansy	Only known from north beach at Shelikof on Kruzof Island, where it has been collected in 2003 and 2013.
Tanacetum vulgare	Common Tansy	Introduced species. Only a few collections in ARCTOS, but (usually multiple) records from most communities in the region indicated in the AKEPIC database.
Taraxacum alaskanum	Alaska Dandelion	Collections of this species in ARCTOS from several islands (Hecata Island, Cornation Island, Baranof Island,Chichagof Island, and Admiralty Island as well as the northern mainland (from Juneau north).
Taraxacum ceratophorum	Horned Dandelion	A few collections in ARCTOS from Southeast Alaska including two from southern outer islands, one from the northern gulf coast, and two from the vicinity of Skagway.
Taraxacum officinale	Dandelion	Widespread throughout much of the region. Most common near towns and at locations with regular human impact, this species has also become naturalized in some remote locations, including shorelines, and stream-side sand and gravel bars.
Taraxacum scopulorum	Alpine Dandelion	The taxonomy seems a little tricky to tease out, but FNA account implies this species does not occur in Southeast Alaska. Could be plants previously identified as this species are Alaska Dandelion (Taraxacum alaskanum). Collections from Southeast Alaska in ARCTOS that come up in a search for this species are either called T. kamtschaticum which in the FNA account is synonymized uner T. alaskanum or T. alaskanum.
Tephroseris frigida	Arctic Groundsel	Apparently no collections of this species from the region, there are reports from northern British Columbia not far from the border. The overall range of this species is primarily north of Southeast Alaska, and if this species occurs in the region, it is likely only at the very northern margin.
Tephroseris lindstroemii	Northern Groundsel	No collections from Southeast Alaska, but there are three records mapped on e-Flora BC which are 25-30 miles from the border near the British Columbia border with Yukon along the Haines Highway.
Tephroseris palustris	Marsh Fleabane	No collections from Southeast Alaska. The nearest appears to be a single report from Atlin Lake in British Columbia.

Balsaminaceae (Jewelweed: 2 species)

Scientific Name	Common Name	Summary
Impatiens glandulifera	Ornamental Jewelweed	Reported primarily from Haines and Juneau, though there is a single report in the AKEPIC from Sitka as well.
Impatiens noli-tangere	Western Touch-me-not	Rare annual herb of meadows, beaches and open forests. A few collections mapped in ARCTOS, mostly on the mainland or near islands from Wrangell north (including Glacier Bay). A single 1950s collection from Kruzof Island is the only one in the western part of the region.

Betulaceae (Birch: 7 species)

Scientific Name	Common Name	Summary
Alnus incana	Thinleaf Alder	Only two (georeferenced) collections in ARCTOS from Southeast Alaska, one from Juneau, another from Haines. FNA distribution maps has this species occurring only east of the coast range in the vicinity of Southeast Alaska.
Alnus rubra	Red Alder	Deciduous tree common in riparian areas and disturbed areas at low elevations. Scattered collections in ARCTOS, mostly from the mainland and inner islands, but also Baranof, Chichagof and Coronation Islands.No collections from Prince of Wales and associated outer islands, nor the northern gulf coast. Presumably it occurs throughout most of the region, though northern Southeast Alaska is considered the northern limit of its range.
Alnus viridis	Sitka Alder	Common deciduous tree-like shrub frequently found along shorelines and colonizing avalanche chutes or mud slide areas. Also found at treeline. Collections from throughout much of the region, with a few gaps (none from Admiralty Island, for example). FNA suggests ssp crispa does not occur in the region, but rather the very similar ssp fruticosa occurs in the northern part of the region (approx. Juneau/Glacier Bay north). From FNA account for ssp fruticosa: "This primarily subarctic Asian subspecies has long been mistaken in western North America for Alnus viridis subsp. crispa, which it closely resembles, or for subsp. sinuata (J. J. Furlow 1983b). It can be separated from the former by its larger and more coarsely toothed leaves, and from the latter by its much thicker, mostly single-toothed leaf blades."
Betula glandulosa	Resin birch	FNA map implies range of this species overlaps with Southeast Alaska along the east side of Lynn Canal. Three georeferenced collections of this species from Southeast Alaska in ARCTOS are two from near Haines and one on Chichagof Island. From FNA: "Plants intermediate between Betula glandulosa and B . nana subsp. exilis make up a continuum of forms linking the typical forms of Betula nana and B . glandulosa in parts of Alaska where the ranges of these species overlap. "
Betula nana	Dwarf birch	FNA map indicates this species range includes the northern mainland of Southeast Alaska. It appears there may not be any (wild) collections that have been determined as this species from Southeast Alaska. ARCTOS includes B. glandulosa in the search results for B. nana.
Betula neoalaskana	Alaska Paper Birch	Not collected from the region, the range given in FNA approaches most closely along the southern border of Yukon Territory. If this species does occur, it is likely only at the margins.
Betula papyrifera	Western Paper Birch	Collections in ARCTOS from Hyder, Juneau, and upper Lynn Canal.

Boraginaceae (Borage: 15 species)

Scientific Name	Common Name	Summary
Amsinckia lycopsoides	Tarweed Fiddleneck	Although included in the preliminary checklist, there are no collections nor any reports of this species in Southeast Alaska, nor in AKEPIC.
Amsinckia menziesii	Menzies' Fiddleneck	Collections in ARCTOS from Skagway (most recently from 1968). No AKEPIC reports of this species from the region, though there are some in that database from the southern Yukon.
Cryptantha torreyana	Torrey's cryptantha	A single 1968 collection from Skagway in ARCTOS. No additional reports of this species from AKEPIC, nor are there any other reports north of extreme southern British Columbia, suggesting this introduced species may not be established in the region.
Lappula occidentalis	Stickseed	A single collection from Mile 14 of Haines highway is the only one in ARCTOS.
Mertensia maritima	Oysterleaf	Collections in ARCTOS from the northern half the region (from southern Admiralty Island), mostly on inside waters (except also at Yakutat). This species is known to occur on the outside on Kruzof Island as was on Haida Gwaii, so it seems likely this species occurs throughout the region.
Mertensia paniculata	Tall Bluebell	There do not appear to be any collections of this species from the region, though it has been reported (collected?) near the border along the Haines Highway as well as at White Pass. Overall distribution seems to be continental.
Myosotis asiatica	Asian forget-me-not	Collections in ARTCOS are called M. alpestris. Only a few collections from the region, including from Ketchikan, Kupreanof Island, three from Chichagof Island (near Freshwater Bay and Tenakee), Auke Bay, and from the mainland mountains outside of Haines. All but the Freshwater Bay and Haines collections are from prior to 1990. Should double check taxonomy. M. asiatica vs. M. alpestris, e-Flora BC appears to treat M. alpestris as a synonym of M. asiatica.
Myosotis laxa	Bay Forget-me-not	No collections from Southeast Alaska, but e-Flora BC has a record from Stewart, British Columbia just across the border from Hyder. It is also known from Haida Gwaii. If this species occurs in Southeast Alaska, it is almost certainly limited to the southernmost part of the region.
Myosotis scorpioides	Forget-me-not	Collections in ARCTOS as well as reports in AKEPIC from many of the communities throughout the region.
Myosotis sylvatica	Woodland Forget-me-not	Although several collections records show up in ARCTOS in a search for this species, none seem to be currently labeled as M. sylvatica. There are reports from Sitka, Hoonah, and Gustavus of this species in AKEPIC.
Plagiobothrys figuratus	Fragrant Popcorn-flower	Although listed in the preliminary checklist, there are no records of this species from the region in ARCTOS. There are also not any reports indicated on e-Flora BC maps, nor in the AKEPIC database.
Plagiobothrys orientalis	Oriental Popcorn-flower	A single collection from 2000 near Skagway is the only record of this species from Southeast Alaska in ARCTOS. This is apparently a disjunct record from the more expected range that stretches westward from Kodiak Island. This species is included on the rare species list for Alaska.
Plagiobothrys scouleri	Scouler's Popcorn-flower	A single collection from 1968 near Skagway is the only record of this species from Southeast Alaska in ARCTOS. There are no additional reports indicated in e-Flora BC maps, nor AKEPIC database. Taxonomy needs clarification, the ARCTOS collection was relabeled P. cognatus, but currently that appears to be a synonym of P. hispidulus.
Symphytum asperum	Prickly Comfrey	Probably not established, this species has only been reported from Sitka (1994).
Symphytum officinale	Common Comfrey	No collections in ARCTOS, but reports from several communities around Southeast Alaska in AKEPIC. Presumably primarily occurs as escaped garden plant, unclear if it has become established anywhere without help.

Brassicaceae (Mustard: 69 species)

Scientific Name	Common Name	Summary
Alliaria petiolata	Garlic Mustard	So far known only from Juneau, where there has been an infestation documented in the downtown area from 2002 to 2013 (at least) based on data in AKEPIC.
Aphragmus eschscholtzianus	Aleutian Cress	Not yet reported; a single report from British Columbia in the small area northwest of Haines. If this species occurs, it is likely to be only at the far northern margins of Southeast Alaska.
Arabidopsis lyrata	Lyrate Rockcress	Collected from much of the region, except for there appears to be no (georeferenced) collections in ARCTOS from the far southern inner islands and mainland.
Arabis eschscholtziana	Eschscholtz's Hairy Rockcress	Several georeferenced collections identified as this species in ARCTOS, but all are from the mainland. Either this species, or Hairy Rockcress (Arabis pycnocarpa) do occur on at least some islands, but additional investigation is needed.
Arabis nuttallii	Nuttalls Rockcress	Not reported from the region, though there are scattered records from near the border in British Columbia, including along the Alsek River in the north and at Stewart (near Hyder) in the south. If this species does make it into Southeast Alaska, it is probably only at the margins.
Arabis pycnocarpa	Hairy Rockcress	A single collection in ARCTOS from the Chilkat Peninsula near Haines. See also Eschscholtz's Hairy Rockcress (Arabis eschscholtziana)
Barbarea orthoceras	American Yellowrocket	As of 2015, nearly 30 collections from throughout much of the region are cataloged in ARCTOS. Probably present throughout, though perhaps never abundant.
Barbarea verna	Early Yellowrocket	Although FNA indicates this introduced species is known from Alaska, there are no collection records in ARCTOS. E-flora BC has a single record from the Taku River very near the border.
Boechera divaricarpa	Uplifting Suncress	Only two collections from the region in ARCTOS, one near Skagway, the other near Haines. Given the overall range of this species, it appears to favor continental type climate.
Boechera lemmonii	Lemmon's suncress	No collection from the region. There is a single collection from nunataks in British Columbia not far from the border.
Boechera retrofracta	Holboell rockcress	A single collection from near Skagway in 2000 is the only collection in ARCTOS. It is labeled as Arabis hoelbellii, but FNA indicates that species is only present in Greenland in North America. E-flora BC has a collection from the Stikine river near the border, as well.
Boechera stricta	Straight-up Suncress	Only two georeferenced collections in ARCTOS from the region, one outside of Haines, the other on the southern tip of Admiralty Island. Additional reports in e-Flora BC from just across the northern border along the highways outside of Haines and Skagway.
Brassica juncea	India Mustard	Although it was included in the preliminary checklist, there are no collections (ARCTOS) nor recent reports (AKEPIC) of this introduced species.
Brassica rapa	Field Mustard	Only a couple of collections in ARCTOS, but AKEPIC records indicate this species has been found in several communities, and is apparently wide-spread along the beaches in Seymour Canal.
Braya humilis	Dwarf Northern Rockcress	There appears to be two collections from the region. One from limestone on Chichagof Island and a second the Alsek River not far from the border.
Cakile edentula	Sea Rocket	Uncommon plant of sandy beaches. Several collections along the outer coast from south Baranof Island north to Yakutat. Additional collections from near Haines, southern Admiralty Island, and the mainland south of Ketchikan.
Cakile maritima	European Sea Rocket	So far known from a single collection from Haines in 2000 and a 2019 photographic record from Kruzof Island. May be moving north and becoming more common in the future. (See the West coast Cakile project )
Camelina sativa	Gold of Pleasure	Introduced plant reported from the Sitka area in the preliminary checklist, though there are no recent observations of this species (AKEPIC) from the region. FNA says "R. L. McGregor (1985) indicated that Camelina sativa is no longer established in North America; we tend to agree because we have not seen any collections made within the past 40 years."
Capsella bursa-pastoris	Shepherd's Purse	Small herb with distinctive heart-shaped fruits found in disturbed areas. Only two georeferenced collections in ARCTOS from the region (one from 1946), but many reports from communities and other areas of significant impact (logging roads/camps) in AKEPIC.
Cardamine angulata	Seaside Bittercress	This species is a Pacific Northwest Coast endemic known primarily from northern California to Washington. In British Columbia it has been reported only on the far southern coast of Vancouver Island and on Haida Gwaii. So far in Southeast Alaska it has been found near Craig on the southern outer coast.
Cardamine bellidifolia	Alpine Bittercress	Most collections are from the northern mainland along from alpine or glacier associated areas. The only island collections are from Baranof Island and Chichagof Island. A single collection from the southern mainland, but given the overall range of this species, it probably occurs throughout in suitable habitat.
Cardamine breweri	Brewer's Bittercress	There are no collections in ARCTOS nor indicated on e-Flora BC of this species from Alasa. However, it was included on the preliminary checklist for Southeast Alaska, as well as in Hall's treatment. Not included in Hulten, but is listed in Anderson.
Cardamine nymanii	Northern Field Bittercress	Formerly C. pratensis ssp angustifolia. There are no collections in ARCTOS (as C. p. angustifolia) from near Southeast Alaska (with many from more northern and western regions). E-flora BC maps have a few records from northern BC, the nearest to our region being at southern Atlin Lake. There are collections of Cuckoo Flower (Cardamine pratensis) - which FNA doesn't indicate occurs in Alaska - from near Yakutat and just across the border from Haines - but the subspecies was not indicated.
Cardamine occidentalis	Western Bittercress	Although Alaska is included in the range of this species in the FNA treatment and it was also included in the preliminary checklist, there are no collections of this species in ARCTOS, nor any indicated on the e-Flora BC maps from anywhere near the region. This a plant later identified as this species was photographed (but not turned into a permanent collection) along the former upper Blue Lake mud flat.
Cardamine oligosperma	Little Western Bittercress	It is unclear whether this species occurs in the region. The range given in FNA includes British Columbia, but not Alaska. Hall's treatment suggests she is referring to the former kamtschatica variety, now known as Umbel Bittercress (Cardamine umbellata) in FNA treatment. Collection records in ARCTOS that show up in a search for this species all are currently identified as C. umbellata. However, e-Flora BC map includes records from through out the province (though it apperas C. umbellata is maintained as C. o. kamtschatica in those records).
Cardamine pensylvanica	Pennsylvania Bittercress	Abundance is unclear. Only two collections in ARCTOS - both from southern mainland (as C. pennsylvanica). It has been suggested the collections may be mis-identified C. flexuosa see note here: https://www.inaturalist.org/observations/9221363
Cardamine pratensis	Cuckoo Flower	Range in FNA treatment indicates this species is primarily from the northeast part of North America though it is also found in British Columbia in the west (though stated range does not include Alaska). FNA also suggests most (if not all) populations of this species are introduced from Europe. Alaska records may be of a former subspecies that is now called Northern Field Bittercress (Cardamine nymanii). ARCTOS has collections (not identified to subspecies) from near Yakutat (including one just across the border in Yukon Territory).
Cardamine umbellata	Umbel Bittercress	Many collections from throughout the region.
Cochlearia groenlandica	Scurvygrass	Only eight collection in ARCTOS, one from Sitka sound, the others from the north end of Prince of Wales Island and nearby associated islands. Probably occurs throughout the region in rocky coastal habitats.
Cochlearia sessilifolia	Annual Scurvygrass	So far only reported from South Central Alaska, and not known to occur in Southeast Alaska. (Only known from Alaska.)
Descurainia incana	Mountain Tansymustard	No collections of this species in ARCTOS from Southeast Alaska, but e-Flora BC has one mapped at Whitepass along the border. Given the overall distribution of this species, if it occurs in the region, it is probably only at the extreme northeast margins.
Descurainia pinnata	Western tansey mustard	There appear to be no records from Alaska of this species. FNA does not include Alaska in the range of any of the subspecies. This species does occur in British Columbia and up to Whitehorse, but there do not appear to be any collections from near the border, and it seems unlikely this species occurs within the region.
Descurainia sophia	Herb sophia	Although it is implied to have been found in the region on the Preliminary checklist, there are no collection records in ARCTOS from Southeast Alaska, nor does the e-Flora BC map include any records from nearby (though it has been found in northern BC). AKEPIC does not have any records in its database either. It seems unlikely that this species is currently established in Southeast Alaska.
Descurainia sophioides	Northern Tansy Mustard	A single 2002 collection from near White Pass. Collection records would imply this is near the southern limit of the normal range for this species.
Draba aurea	Golden Rockcress	The overall collection record of this species (from ARCTOS and e-Flora BC) suggest the range of this species is primarily on the inland side of the coast mountains as well as into the rocky mountains. There are not any collections in ARCTOS from Southeast Alaska of this species (though there are 4 records that show up in a search, but all are currently identified as Northern rockcress (Draba borealis)).
Draba borealis	Northern rockcress	A handful of collections from the region are in ARCTOS, with most near the northern border, but one from Coronation Island as well.
Draba cana	Cushion Draba	A single collection from mountains north of Glacier Bay and west of Haines is the only record from Southeast Alaska in ARCTOS.
Draba cinerea	Gray-leaved Draba	A single collection in ARCTOS from the mountains north Glacier Bay and west of Haines. This appears to be at the southern edge of its range.
Draba corymbosa	Flat-top Draba	D. eschscholtzii was included in the preliminary checklist, though it seems this name may be misapplied to plants in North America (see discussion at pan arctic flora site). It is not entirely clear what the best alternative may be, however D. corymbosa seems plausible. In any case, there appear to be no documented collections of this species from the region at present, though there are three records from the Haines triangle region of British Columbia included in maps on e-Flora BC.
Draba crassifolia	Snowbed Draba	Four collections in ARCTOS, all from mountains on the mainland, three from Juneau north, and one from the Cleveland Peninsula.
Draba glabella	Rock Whitlow-grass	This species has been collected from White Pass near Skagway, Greens Creek area on Admiralty Island, and from above Rust Lake on Chichagof Island. The latter appear to the the southernmost records of this species in western North America.
Draba grandis	North Pacific Rockcress	Only four collections georeferenced in ARCTOS, all from the outer coast. PacNW herbarium records show a collection from Kashevarof Island (it was described as common), the only one away from the outer coast. (Patchy, rare or absent on inside waters?)
Draba incerta	Yellowstone Draba	Overall range of this species appears to favor the east side of the coast range, but there are two collections of this species in ARCTOS from northern Prince of Wales Island.
Draba juvenilis	Long-stalked Draba	Three collections from the region in ARCTOS, two on limestone areas of Chichagof Island, and one from the Juneau Icefield. Southeast Alaska is at the southern margin of the overall range of this species.
Draba lonchocarpa	Lance-pod draba	A dozen collections from the region in ARCTOS, most from the northeastern mainland, but also from Baranof Island, Hecata Island, and Prince of Wales Island, and one collection from the south central mainland. Habitat in Southeast Alaska appears to be limited to the alpine.
Draba nemorosa	Woodland Draba	No collections from the region. The nearest reports appear to be from the interior beyond the coast mountain range. It seems unlikely this species occurs in Southeast Alaska.
Draba nivalis	Snow draba	Although it was included on the preliminary checklist, there are no records of this species from the region that are georeferenced in ARCTOS, nor any that show up on e-Flora BC map. The overall range of this species is almost entirely north and/or west of Southeast Alaska. One observation on iNaturalist identified as this [1] ID notes from FNA treatment: Draba nivalis is most often confused with D. lonchocarpa, and C. L. Hitchcock (1941) reduced the latter to a variety (var. elongata) of D. nivalis. A critical comparison reveals that there are enough differences to warrant their recognition as distinct species. Draba nivalis is distinguished by having non-ciliate leaf bases, basal leaf blades pubescent with trichomes 0.05-0.15 mm, stems and pedicels that are always pubescent, and fruits that are elliptic to narrowly elliptic-oblong, plane, and 3.5-9 mm. By contrast, D. lonchocarpa has ciliate leaf bases, basal leaf blades pubescent with trichomes 0.15-0.5 mm, stems and pedicels that are glabrous or sparsely pubescent, and fruits that are linear to lanceolate or oblong, slightly twisted or plane, and 6-15(-18) mm. Except for Alaska, D. nivalis does not grow in the continental United States, whereas D. lonchocarpa grows in nearly all Mountain and Pacific states.
Draba oligosperma	Few-seeded draba	There are not collections indicated in ARCTOS, nor on e-flora BC maps from the region. Overall range of this species appears to be primarily in the Rocky Mountains, with the nearest collections to Southeast Alaska in the southern Yukon Territories. It seems unlikely this species occurs in our region.
Draba praealta	Tall Whitlow-grass	A single collection in ARCTOS from Takhin Ridge in the mountains between Glacier Bay and Haines. FNA author doesn't consider this species well-substantiated in the Alaska.
Draba ruaxes	Rainier draba	There appear to be no collections from Southeast Alaska, but there is one from Yukon Territory right along the border north of Yakutat.
Draba stenoloba	Alaska draba	Several collections in ARCTOS from the region, with most from the area north of Lynn Canal. Additional collections on the mainland from the area north of Yakutat and one from the mainland east of Wrangell suggest this species may show up at least occasionally in the coast mountains of the mainland throughout. A single collection from Admiralty Island is the only island record in the region.
Erysimum cheiranthoides	Wormseed	Overall distribution of this species is unclear. There are a handful of collections, mostly from northern Lynn Canal, but also one from Chichagof Island at/near Todd Cannery site. Oldest collection is from Haines in 1949. Also present in Sitka. Although FNA indicates this is an introduced species it does not seem to be tracked in AKEPIC database.
Erysimum inconspicuum	Shy Wallflower	There do not appear to be any collections from the region. The distribution of this species seems to indicate a preference for a more continental climate, and is perhaps unlikely to occur in Southeast Alaska.
Hesperis matronalis	Sweet-rocket	Few actual collections, but there are reports from several communities in the AKEPIC database. This species is not infrequently grown as an ornamental plant, and it may be that many of the observations are from intentional plantings.
Lepidium densiflorum	Common Pepperweed	Although included on the preliminary checklist and in Hall's treatment, there are no collections in ARCTOS, nor a reports of this species in the AKEPIC database.
Lepidium virginicum	Wild Peppergrass	Although included in the preliminary checklist, there are no collections in ARCTOS, nor any in the AKEPIC database, so it seems unlikely that this species is currently present in the region.
Parrya nudicaulis	Nakedstem Wallflower	Although included in Hall's treatment, there are not any records from Southeast Alaska in ARCTOS, and the overall distribution of collections of this species would suggest it's unlikely to occur in Southeast Alaska except possibly at the northern margins.
Physaria arctica	Arctic Bladderpod	No collections or reports from Southeast Alaska, but there are two records on e-Flora BC maps from the Tatshenshini River in the Haines triangle of British Columbia. If this species occurs in the region, it is probably only at the margins.
Raphanus sativus	Garden Radish	No collection records from the region in ARCTOS. Nor any reports in AKEPIC database. A plant thought to be this species has been seen at Pirate's Cove near Sitka.
Rorippa curvipes	Bluntleaf Yellowcress	Although listed in the preliminary checklist, the FNA does not consider this species to occur in Alaska, and there are no collections especially near to Southeast Alaska. It appears that it's primary range probably goes as far north as the southern half of British Columbia.
Rorippa curvisiliqua	Western Yellowcress	Only two collections from Southeast Alaska, one at Hyder and another at Glacier Bay. Also a collection along the Haines Highway on the BC side of the border.
Rorippa palustris	Marsh Yellowcress	More than a dozen collections scattered throughout the region, with significant gaps.
Sinapis alba	Charlock Mustard	A single record in AKEPIC from the Klawock Airport in 2004. Reported to have 50% canopy cover in a .1 acre area, it was also noted that species was uncertain.
Sinapis arvensis	Charlock	Although included on the preliminary checklist, there appears to be no collection records of this species from the region, nor any records from AKEPIC.
Sisymbrium altissimum	Tall Tumble Mustard	Collections in ARCTOS from Juneau, Haines, and Skagway. None are georeferenced, all from prior to 1940. Only a single recent report from Klukwan in 2007 from AKEPIC database. This species may not be established in the region.
Sisymbrium officinale	Hedge Mustard	A 2009 collection from Hoonah is the only recent one in ARCTOS (though there may be others from the early 1900s). Only one recent report in AKEPIC, from Prince of Wales Island. AKEPIC also reports a 1916 citation from Anderson of this species occurring in Sitka. It is unclear whether this species is currently established in the region.
Subularia aquatica	Awlwort	Only four collections in ARCTOS, one from near Ketchikan, another from the Stikine River, one on Kruzof Island near Sitka, and last near Yakutat.
Thlaspi arvense	Field Pennycress	Four collections in ARCTOS, from Juneau, near Haines, and Skagway. An additional (2006) record from Kake and three (2007) from Haines in AKEPIC. Seems likely to be established in the Haines area, elsewhere is unclear.
Turritis glabra	Tower Rockcress	Several old collections in ARCTOS from Haines area, and one 1941 collection from Kake. AKEPIC includes several reports from Haines area cites one historical collection (1929) from Sitka. Given the records, it seems like this species is established in the Haines area, but perhaps not elsewhere.

Cabombaceae ( 1 species)

Scientific Name	Common Name	Summary
Brasenia schreberi	Watershield	Aquatic perennial herb with oval to elliptic floating leaves and purplish solitary flowers Only collected from Gravina Island and Duke Island in the extreme southern part of the region. Apparently nearest other reports are from southern British Columbia.

Callitrichaceae (Water-starwort: 3 species)

Scientific Name	Common Name	Summary
Callitriche hermaphroditica	Northern Water-starwort	A single collection from near Disenchantment Bay outside of Yakutat is the only record from the region.
Callitriche heterophylla	Two-headed Water-starwort	Four collections from the southern half of the region. Overall distribution of this species suggests it should be expected throughout. It is unclear whether this species is mostly overlooked (uncollected), or relatively uncommon with only scattered occurrences.
Callitriche palustris	Spring Water-starwort	Probably occurs throughout. Several collections from throughout much of the region. Apparently no collections from southern outer islands, nor northern Lynn Canal.

Campanulaceae (Harebell: 5 species)

Scientific Name	Common Name	Summary
Campanula lasiocarpa	Mountain Harebell	Uncommon plant of subalpine meadows extending to above the treeline. All but two georeferenced collections of this species come from the northern mainland, including the mountains around Lynn Canal from Juneau north, and the mountains in the vicinity of Yakutat. Island records from northern Admiralty and from Baranof Island. There appear to be few collection records from coastal areas south of the region. It is unclear whether this species occurs (or should be expected) in the southern part of the region.
Campanula rotundifolia	Common Harebell	Common blue-flowered herb of open areas including beaches, river banks, meadows, and cliffs. Many collections in ARCTOS from throughout the region.
Campanula scouleri	Scouler's Harebell	Apparently no collections from the region. E-flora BC map shows no collections north of southern-most coastal British Columbia. It is included in both the preliminary checklist and in Hall's 2010 treatment, but actual distribution (or even presence) in the region probably needs further documentation.
Campanula uniflora	Arctic Harebell	Only two collections of this species in ARCTOS, both from Admiralty Island near the Greens Creek Mine. Primary range appears to be more from arctic/alpine tundra (including much of Alaska, but also the Rocky Mountains).
Lobelia dortmanna	Water Lobelia	Only two collections, both from the very southern end of the region. These are the furthest north of this species on the west coast of North America.

Caprifoliaceae (Honeysuckle: 3 species)

Scientific Name	Common Name	Summary
Linnaea borealis	Twinflower	Inconspicuous trailing perennial common in scrubby forests and muskeg edges. Many collections from throughout much of the region. Probably fairly common throughout in appropriate habitat.
Lonicera involucrata	Bearberry honeysuckle	Although reported to occur in the northern part of the region, all the collections are from the middle of Prince of Wales Island south.
Symphoricarpos albus	Snowberry	Four georeferenced collections in ARCTOS, all from the vicinity of Haines. Introduced as an ornamental in some communities.

Caryophyllaceae (Pink: 40 species)

Scientific Name	Common Name	Summary
Agrostemma githago	Common Corncockle	Although the preliminary checklist includes this species as introduced in the Sitka area, there are no records in ARCTOS, nor any reports in AKEPIC. It is not considered established in British Columbia. It seems unlikely to be established in Southeast Alaska.
Cerastium arvense	Field Chickweed	Collections primarily from the vicinity of upper Lynn Canal. However, a handful of collections from outer islands, Baranof, northern Prince of Wales, and Coronation.
Cerastium beeringianum	Bering Chickweed	Several collections from the northern Lynn Canal and Gulf Coast, but also some from the southern part of the region, including on islands. (However, not all of those appear to have been verified, and that may be advisable given the difficulty of this genus.)
Cerastium fischerianum	Fischer's Chickweed	A single (non-georeferenced) collection from Juneau vicinity is the only one in Arctos from the region. Overall distribution of this species in Norther America appears to be primarily from Kodiak Island westward. There are a couple of BC records from Haida Gwaii and Vancouver Island, so this species could be expected to occur at least occasionally, probably mostly in alpine habitats.
Cerastium fontanum	Big Chickweed	Introduced species that appears to be widespread throughout the region in disturbed areas (including logging roads) with collections in ARCTOS and additional records in AKEPIC.
Cerastium glomeratum	Mouse-ear Chickweed	Distribution in the region is somewhat unclear. Only a small number of collections and/or reports. Most introduced weedy species appear to be Big Chickweed (Cerastium fontanum) rather than this species (based on collection records).
Honckenya peploides	Beach Greens	Common plant of the upper beach on rocky shores. Collections from throughout the region, with the primary gap being much of the southern outer islands.
Minuartia biflora	Mountain Sandwort	Four collection records in ARCTOS - three from the northern mainland (vicinity of Lynn Canal) and one from Prince of Wales Island. All collections from alpine areas.
Minuartia elegans	Elegant sandwort	So far only records are from Baranof Island on Bear Mountain (and possibly Starrigavan Ridge) near Sitka. Except for along the Bering Sea, this has been reported mostly from continental side of the mountains, but there are at least a couple of ocean side records from British Columbia and Washington (though FNA account suggests those may be a different species), as well as a couple from Kodiak Island.
Minuartia macrocarpa	Large-fruited Sandwort	A single collection from the Taiya River outside of Skagway. This appears to be one of the (south) eastern-most records in North America.
Minuartia obtusiloba	Alpine sandwort	Included in the preliminary checklist. It is not clear if there are any collections from the region, though there are several from very close to it along the northern margins. There may need to be some review of this species and Mountain Sandwort (Minuartia biflora)
Minuartia rossii	Ross's sandwort	Although included on the preliminary checklist, there are no documented collections of this species from the region in ARCTOS, nor any indicated from British Columbia (it is not included in e-Flora BC). The nearest collections appear to be room the Yukon and Wrangell-St. Elias area of the main part of Alaska.
Minuartia rubella	Reddish sandwort	Several collections from the region. Distribution of collections suggest this species probably occurs throughout much of the region, though perhaps in limited and/or under sampled habitats.
Minuartia stricta	Rock sandwort	Although reported on the preliminary checklist, there do not appear to be any collections from the region.
Moehringia lateriflora	Blunt-leaved Sandwort	Quite a few collections from the northern part of the region. Based on collection records, this species would seem to be non-coastal in western North America south of where it occurs in Southeast Alaska (north and west of the region it has frequently been collected in coastal areas). Southern-most collections in the region are from norther Chichagof Island, but it has also been found on northern Kruzof Island.
Sagina maxima	Beach Pearlwort	Common small herb of the splash zone along rocky shorelines. Probably occurs throughout, though collections are primarily from the southern half of the region (with one from the Yakutat area as well).
Sagina nivalis	Snow Pearlwort	A few collections from the northern mainland, including the gulf coast, Glacier Bay, and White Pass. A collection from British Columbia near Hyder suggests this species may occur in the coastal mountains elsewhere in the region as well.
Sagina procumbens	Bird's Eye Pearlwort	Introduced species with only three collections in ARCTOS (including one from 1939). Many reports, primarily from near Sitka and the eastern half of Chichagof Islands, in AKEPIC database.
Sagina saginoides	Arctic Pearlwort	Several collections from the northern mainland. There are records from Haida Gwaii, so perhaps this species may be found on islands in Southeast Alaska at some point.
Silene acaulis	Moss Campion	Collections scattered throughout much of the region. Apparently no (recent, georeferenced) collections from several of the major islands, including Admiralty, Baranof, and Chichagof.
Silene involucrata	Arctic catchflly	Apparently no recent (georeferenced) collections from the region. There may be older collections in ARCTOS that have not been georeferenced. ssp. involucrata seems to be the expected one for this region.
Silene menziesii	Menzies' Campion	No recent (georeferenced) collections from Southeast Alaska. Two older collections from from Skagway (1934) and Juneau (1925).
Silene noctiflora	Night-flowering Catchfly	There seem to be no recent reports. Reported by Anderson in 1918 publication on plant of Southeast Alaska.
Silene soczavana	Boreal Catchfly	Collections from Baranof Island and Dall Island. Taxonomy of this species and the related Apetalous Catchfly (Silene uralensis) may not yet be settled.
Silene uralensis	Apetalous Catchfly	Collections from West Chichagof, Northern Admiralty Island, and northern Prince of Wales Island. See also Boreal Catchfly (Silene soczavana) (some of the collections for S. uralensis may need to be reviewed to see if they are S. soczavana)
Spergula arvensis	Corn Spurry	Only two collections in ARCTOS (from Ketchikan and Haines), but many reports in AKEPIC database from Juneau and Haines areas.
Spergularia canadensis	Canada Sand-spurry	Collections from across the region (though apparently none from Baranof Island, where it does occur).
Spergularia rubra	Red Sandspurry	A single collection from Haines in ARCTOS. Several reports in AKEPIC database from the Haines area as well as Juneau.
Stellaria alaskana	Alaska Starwort	Included in the preliminary checklist and Hall's 2010 treatment, but there are no collection records from the region in ARCTOS. This species is not known to occur in British Columbia, so additional documentation of its occurrence in Southeast Alaska may be warranted.
Stellaria borealis	Boreal Starwort	Collections from throughout the region with both subspecies (borealis and sitchana) represented.
Stellaria calycantha	Northern Starwort	Several collections scattered throughout the region with some gaps (no collections from the northern islands, for example). Presumably occurs throughout, though perhaps not as commonly as Boreal Starwort (Stellaria borealis), which was formerly considered a subspecies of this.
Stellaria crassifolia	Fleshy Starwort	Apparently one collection of this species from the region at the Stikine River mouth. Overall distribution of collections tends towards more inland and/or northerly locations, so its occurrence in Southeast Alaska may be marginal.
Stellaria crispa	Curled Starwort	Scattered collections throughout the region, but with gaps. Apparently no collections from Chichagof Island, Admiralty Island, nor the southern outer islands.
Stellaria humifusa	Saltmarsh Starwort	Collections from throughout the region.
Stellaria longifolia	Long-leaved Starwort	Only a handful of collections from the region identified as this species in ARCTOS. All are from the northern part.
Stellaria longipes	Long-stalked Starwort	Collections from the northern half of the region. Conspicuously absent in the southern part. Although collected many times from interior British Columbia, there is only a single (1914) collection from the coastal areas north of Vancouver Island.
Stellaria media	Common Chickweed	Only a few collections in ARCTOS, but may reports from throughout the region in AKEPIC database. It is unclear to what extent this species is present away from regular human disturbance.
Stellaria ruscifolia	Prickly-leaved Starwort	Included in the preliminary checklist as well as Hall's 2010, the FNA treatment for this species shows Southeast Alaska included in the distribution of this species. However, there are no collections in ARCTOS of this species from Southeast Alaska.
Vaccaria hispanica	Cow Soapwort	Only two records, both old, from the region. A 1929 collection in ARCTOS frm Juneau, and a citation (found in AKEPIC database) of a 1916 publication by Anderson indicating it had been found in Sitka. Probably no longer occurs in the region.
Wilhelmsia physodes	Merckia	Included in the Preliminary checklist and in Hall's 2010 treatment, but there are no records from British Columbia, nor are there any georeferenced records from Southeast Alaska. (There are a quite a few records in ARCTOS without any geolocation data, and it is possible that an older collection or two from Southeast Alaska is among them.) The nearest collection records appear to be from well into the Yukon Territory or near Prince William Sound.

Chenopodiaceae (Goosefoot: 7 species)

Scientific Name	Common Name	Summary
Atriplex gmelinii	Gmelin's Saltbrush	On beaches, Locally abundant to absent. Collections in ARCTOS from throughout much of the region.
Atriplex patula	Spearscale	It appears there may be some confusion between this species and Gmelin's Saltbrush (Atriplex gmelinii). Based on the FNA account, it would seem this species should not be expected in salt rich areas (i.e., beaches) while A. gmelinii is restricted to such locations. There are a few collections in ARCTOS identified as this species (though all of those are from beach habitats, and maybe have been named with a broader understanding of A. patula than used in FNA) and two reports in AKEPIC (though those appear to be on shorelines, so may need reconsideration).
Chenopodium album	Lamb's Quarters	Although there are reports in the AKEPIC database from a few places around the region, the only collections in ARCTOS are from the north end of Lynn Canal (Haines and Skagway). This species is similar to Gmelin's Saltbrush (Atriplex gmelinii), so it would be nice to verify observations reported from the beach habitats of that species.
Chenopodium capitatum	Strawberry spinach	Annual weedy herb with slightly fleshy arrow-shaped leaves and dense red clusters of fruit. A single (georeferenced) collection in ARCTOS from Andrew Island in the Stikine River. Apparently not included in AKEPIC.
Salicornia depressa	Beach Asparagus	There are several collections that resolve to this species in ARCTOS, however at least some of those may actually be Beach Asparagus (Sarcocornia perennis). FNA distribution map has this species occurring throughout coastal BC and again on the east side of Cook Inlet, but absent in Southeast Alaska. It seems like this species does occur in the region, but more investigation is need to clearly resolve the question.
Sarcocornia perennis	Beach Asparagus	Only one collection identified as this species in ARCTOS, though more as Salicornia virginica, which presumably are of this species. Taxonomy of this group is apparently a little confusing. FNA has 'all Salicornia spp as annuals, with Sarcocornia spp being perennial.
Suaeda calceoliformis	Sea blite	Only one collection in ARCTOS identified as this species. Additional collections identified as S. maritima may also be this species, as the FNA treatment indicates that species is not known from the Pacific Coast of North America. Given the relatively few collections from the region as well from coastal BC, this species is probably not common in Southeast Alaska.

Clusiaceae (Mangosteen: 1 species)

Scientific Name	Common Name	Summary
Hypericum perforatum	Common St. John's-wort	Reported mostly from the southern half of the region, but also in Hoonah. A few collections in ARCTOS, with many additional records in the AKEPIC database.

Cornaceae (Dogwood: 4 species)

Scientific Name	Common Name	Summary
Cornus canadensis	Bunchberry	Common in forests, forest edges, and some open areas. There are many collections in ARCTOS identified as this species. However, strictly speaking, it may be that at least some of the are Western Cordilleran Bunchberry (Cornus unalaschkensis), the hybrid between this species and Bog Bunchberry (Cornus suecica). In the Sitka area, it seems there are very few plants with flower petals that do not have purple on them to at least a certain extent, and it may be similar in other parts of the region.
Cornus sericea	Red-osier Dogwood	Collections in ARCTOS from throughout much of the region away from the outer coast. There are no collections from the gulf coast, nor the west side of the outer islands. (One partial exception is a collection from the north half of Prince of Wales Island.)
Cornus suecica	Bog Bunchberry	Fairly Common perennial herb in muskegs. Several collections scattered from throughout the region identified as this species in ARCTOS (also some additional ones identified as intermediate between this species and Cornus canadensis). Apparently Southeast Alaska is near the southern limit of this species in western North America, as there appears to be only a single collection from coastal British Columbia (where it is a listed species).
Cornus unalaschkensis	Western Cordilleran Bunchberry	Probably Fairly Common. Collections from through out much of the region (including some identified as hybrids between this species and Bunchberry (Cornus canadensis)).

Crassulaceae (Stonecrop: 5 species)

Scientific Name	Common Name	Summary
Crassula aquatica	Water Pygmyweed	So far known only a collection at Chief Shakes Hotsprings along the Stikine River
Rhodiola integrifolia	Ledge Stonecrop	Presumably found throughout the region. Collections in ARCTOS from throughout much of Southeast, though with the exception of a collection from southwest Chichagof Island, there is a gap between the southern half of the region and south of Juneau.
Sedum divergens	Pacific Stonecrop	Southeast Alaska appears to be near the northern extent of the range of this species. Collections from near Haines (two at mile 10 of Haines highway from 1967 and 1981) and one from Takhin Ridge (2000). Other nearby collections include from near Disentchantment Bay, and from across the border near the Stikine River.
Sedum lanceolatum	Spear-leaved Stonecrop	There appear to be no collections from the region in ARCTOS. The overall range of this species appears to be primarily continental, and there are collections from just across the border along the northern mainland.
Sedum oreganum	Oregon Stonecrop	Collected from Baranof Lake (1963, still present in 2011), with an additional collection on the Canadian side of the border along the highway out of Haines. In 2012 a population was found on rocks above high tide at Whitewater Bay on Admiralty Island (E. Anderson via K. LaBounty). Additional records from near Haines (date unknown), two on Southern Admiralty (listed as 1937 and 1942), and Hyder (1940) are shown on the species occurrence map at AKNHP. (The latter three may be 3 collections in ARCTOS that have not been georeferenced.)

Diapensiaceae ( 1 species)

Scientific Name	Common Name	Summary
Diapensia obovata	Diapensia	No georeferenced collections in ARCTOS (though there are quite a few collections not georeferenced, and it may be that one or more of those is from Southeast Alaska). I single point on the e-Flora BC map for a collection from Lynn Canal.

Droseraceae (Sundew: 3 species)

Scientific Name	Common Name	Summary
Drosera anglica	Long-leaf Sundew	Small, insectivorous perennial infrequently found in bogs and meadows. Collections span the region, though most are in the southern half on the inside and mainland.
Drosera rotundifolia	Round-leaf Sundew	Common, but easily overlooked insectivorous perennial of muskegs Collections from throughout the region.
Drosera x obovata	Sundew Hybrid	This hybrid between Round-leaf Sundew (Drosera rotundifolia) and Long-leaf Sundew (Drosera anglica) has been reported to occur in Southeast Alaska, though there appear to be no collections in ARCTOS.

Elaeagnaceae (Oleaster: 1 species)

Scientific Name	Common Name	Summary
Shepherdia canadensis	Soapberry	Several collections in ARCTOS, though all are from the northern mainland part of the region (but not the gulf coast).

Ericaceae (Heather: 35 species)

Scientific Name	Common Name	Summary
Andromeda polifolia	Bog Rosemary	Bog Rosemary is a small easily overlooked evergreen perennial found in bogs. Plants typically consist of a few slender stems, so are most noticeable when the pink urn-shaped flowers are blooming. Like many bog plants, the leaves contain a variety of toxins and should not be consumed . Scattered collections (15 georeferenced) from across the region. Probably under collected relative to its abundance.
Arctostaphylos uva-ursi	Kinnikinnick	A few scattered collections in ARCTOS, mostly from the northern mainland, but also near Hyder, on eastern Baranof Island, and from Coronation Island. (There may be additional records that have not been georeferenced).
Arctous alpinus	Alpine Bearberry	Included in Hall's 2010 treatment, but apparently no records from Southeast Alaska (or anywhere close) in ARCTOS. However, Hall does not include Red-fruit Bearberry (Arctous rubra), which has been collected from the region. (A. rubra appears to formerly have been considered a subspecies of this species.)
Arctous rubra	Red-fruit Bearberry	Only a handful of georeferenced collections from the region in ARCTOS (there are many records without georeferencing, and some may be from the region). Collections from the northern mainland, as well as Prince of Wales and Chichagof Island.
Cassiope lycopodioides	Club-moss Mountain-heather	Probably uncommon small evergreen trailing shrub. Several collections in ARCTOS, but most from the northern mainland near Juneau with three more from the southern mainland and Revillagigedo Island.
Cassiope mertensiana	White Mountain Heather	Common mat-forming evergreen heather found in the low alpine near and above treeline. Over 30 collections in ARCTOS, most from the mainland (excluding the northern gulf coast) and inner islands. Also collected on Baranof Island and a single collection in the St. Elias mountains near the border along the Alsek River.
Cassiope tetragona	White Arctic Mountain Heather	Several collections in ARCTOS from the northern mainland (mostly either north or east of Lynn Canal).
Chimaphila umbellata	Pipsissewa	Collections in ARCTOS primarily from the vicinity of Haines, but also collections from Beardsley Islands in Glacier Bay, Gull Island in Lynn Canal, along the Taku River, and near Hyder.
Elliottia pyroliflora	Copperbush	Deciduous shrub with glossy,yellow green leaves and showy copper-colored flowers common near treeline, uncommon at lower elevations. Collections from throughout the region.
Empetrum nigrum	Crowberry	Common evergreen shrub with needle shaped leaves found in muskegs and open subalpine areas at or just above treeline and on rocks at the shore line. Collections in ARCTOS from throughout the region.
Gaultheria shallon	Salal	Several collections in ARCTOS, most at or south of a line from Etolin Island to Coronation Island. Two collections from Baranof Island in the vicinity of Goddard Hot Springs.
Harrimanella stelleriana	Alaska Mountain Heather	Small evergreen shrub common in subalpine to lower alpine meadows and heath, less common in lower elevation muskeg and open forest. Collections from throughout the region, though there are gaps including Chichagof Island and Admiralty Island.
Kalmia microphylla	Bog Laurel	Collections in ARCTOS from throughout the region, but under Kalmia polifolia (which, as of June 2016, has apparently not been considered a synonym of K. microphylla in the ARCTOS taxonomy).
Kalmia procumbens	Alpine Azalea	Also known as Loiseleuria procumbens in many references Collections in ARCTOS from across the region.
Menziesia ferruginea	Rusty Menziesia	Collections in ARCTOS span the region, but there are gaps (such as Chichagof Island and Admiralty Island) where this species certainly occurs.
Moneses uniflora	Single Delight	Collections in ARCTOS from across the region.
Monotropa hypopitys	American Pinesap	Uncommon to Fairly Common species of forested areas from low to middle elevations. Abundance seems to vary by year. Scattered collections mostly from the eastern mainland and inner islands, but also from Baranof and Chichagof Islands.
Monotropa uniflora	Indian-pipe	A single collection (Hyder, 1939) in ARCTOS. Collections from BC near Southeast Alaska are east of the coast range, while coastal collections are no further north than the southern half of Vancouver Island.
Orthilia secunda	One-sided Wintergreen	A good number of collections in ARCTOS, but mostly from the northern half of the region. Also a few from the southern mainland. It is unclear whether this is due to the distribution of the species, or uneven collecting efforts.
Phyllodoce empetriformis	Pink Mountain-heather	Few collections from the region in ARCTOS or on e-Flora BC map, all from near the northern border with British Columbia outside of Haines and Skagway. One additional report from Etolin Island. Over all distribution of this species appears to reach its northern and western extent in the southern Yukon Territory, with occurrence in the northern part of its range primarily on the continental side of the coast range.
Phyllodoce glanduliflora	Yellow Mountain Heather	Fairly common needle-leaved small shrub found from low to upper elevations. Collections in ARCTOS from throughout the region.
Pyrola asarifolia	Liverleaf Wintergreen	Several collections in ARCTOS spanning north to south, but primarily limited to the mainland. Exceptions include two collections from the east side of Chichagof Island and one collection from Mitkof Island.
Pyrola chlorantha	Green-flowered Wintergreen	Apparently only a few collections in ARCTOS identified as this species (though many more identified as Pyrola minor show up in a search for this name). Collections from Chichagof Island, Glacier Bay, and upper Lynn Canal.
Pyrola minor	Lesser Wintergreen	ARCTOS records indicate scattered collections along the outer coast, quite a few additional collections from the vicinity of Juneau and upper Lynn Canal. A single collection from northern Admiralty Island is the only one on the inner islands. Just two collections from the mainland south of Juneau, both in the vicinity of Hyder.
Rhododendron camtschaticum	Kamchatka Rhododendron	Only three collections in ARCTOS, all from the northwestern part of the region (from Yakobi Island to Yakutat). Additional reports from Mt. Edgecumbe (2009, photo) and northern Chichagof Island (near Elfin Cove). Hall reports this species is present in the mountains above Juneau.
Rhododendron groenlandicum	Labrador Tea	Small evergreen shrub with aromatic leaves and white flowers found in most muskegs. Georeferenced collecctions in ARCTOS primarily from the southern half of the region and in the Juneau vicinity. A few scattered collections elsewhere in the region.
Rhododendron tomentosum	Narrow-leaf Labrador tea	This species appears to reach its southern extent (on the east side of its range) in the very northern part of the region. There appear to be very few collections, all from the upper end of Lynn Canal. (A search in ARCTOS includes many collections currently identified as Rhododendron groenlandicum, which may have previously been thought to be this species.)
Vaccinium alaskaense	Alaska Blueberry	Treated as a synonym of V. ovalifolium in the Flora of North America, there seems to be a distinct difference between the plants thought of as this species and those of V. ovalifolium in the Sitka area, at least. This species tends to bloom later (after leaves are out) have much flowers which are distinctly less elongate, and fruit that is noticably darker (with a different flavor). Further investigations, including some genetic work, are on-going. ARCTOS collection records primarily from the southern half of the region and in the immediate vicinity of Juneau.
Vaccinium cespitosum	Dwarf Blueberry	ARCTOS collection records scattered across the region.
Vaccinium membranaceum	Thinleaf Huckleberry	Not reported from Southeast Alaska, though there are collections from British Columbia not far from the border. This species appears to primarily occur in inland locations in the northern part of its range (though it is coastal in southern BC).
Vaccinium ovalifolium	Early Blueberry	Collections in ARCTOS from throughout the region, though not as many from outer islands and the gulf coast, and apparently none from Admiralty Island.
Vaccinium oxycoccos	Bog Cranberry	Collections in ARCTOS from across the region.
Vaccinium parvifolium	Red Huckleberry	Fairly common deciduous shrub in much of southeastern Alaska. The berries are enjoyed by both people and other animals. Most collections in ARCTOS from southern half of the region (including Sitka), but also several from Juneau and at least one from Gustavus.
Vaccinium uliginosum	Bog Blueberry	Fairly common dwarf deciduous blueberry found in bogs and alpine tundra Collections in ARCTOS from throughout the region.
Vaccinium vitis-idaea	Lingonberry	A Fairly Common dwarf evergreen shrub found in bogs, open forests and the highest portions of uplift meadows. Collections in ARCTOS from throughout the region.

Fabaceae (Pea: 45 species)

Scientific Name	Common Name	Summary
Astragalus agrestis	Purple Milk Vetch	Although included in the preliminary checklist, there do not appear to be any collections from especially near Southeast Alaska. The nearest indicated on e-Flora BC maps are in the vicinity of the alcan highway in southern Yukon.
Astragalus alpinus	Alpine Milk-vetch	Most (georeferenced) collections in ARCTOS are from the northern mainland. Two collections from Baranof Island (Bear Mountain and Blue Lake), plus one from northern Prince of Wales Island.
Astragalus americanus	American Milkvetch	Probably does not occur in the region, but collection is shown on the e-Flora BC map from the Stikine River near the border (it may be this is a location such "Stikine River" with a very wide circle, as there are no other records from particularly near the border.)
Astragalus bodinii	Bodin's Milk-vetch	Although included on the preliminary checklist, there do not seem to be any collections from Southeast Alaska in ARCTOS, nor is this species reported from British Columbia. Hulten does include part of Southeast Alaska in the presumed range (based on collections, though it is unclear where they may be currently).
Astragalus eucosmus	Elegant Milk-vetch	Included on the preliminary checklist as well as in Hall's 2010 treatment, there do not appear to be any collections from particularly close to Southeast Alaska. The overall range of this species appears to be very continental (especially at latitudes encompassing this region).
Astragalus nutzotinensis	Nutzotin milk-vetch	Included on the preliminary checklist, but there do not appear to be any collections in ARCTOS nor indicated on the e-Flora BC map from the region. There are several collections from the Haines Triangle of British Columbia, however.
Astragalus robbinsii	Harold's Milk-vetch	A few collections (mostly as A. harringtonii) in ARCTOS, from Chichagof Island, Yakutat area, Glacier Bay, and Dall Island.
Astragalus umbellatus	Tundra milk vetch	No georeferenced collections in ARCTOS from the region, there are collections very near the border outside of Haines on the British Columbia side.
Cytisus scoparius	Scots Broom	Unclear to what extent this species has escaped cultivation in Southeast Alaska. Records in AKEPIC primarly from Prince of Wales Island, but also from other southern Southeast Alaskan communities as well as Sitka, Petersburg, and Hoonah.
Hedysarum alpinum	Alpine Sweet-vetch	Several collections in ARCTOS from the northern mainland part of the region.
Hedysarum boreale	Northern Sweet-vetch	ARCTOS Collections from near Haines and one from the lower Alsek river about 1 mile west of the border.
Lathyrus japonicus	Beach Pea	Sprawling perennial with purple pea flowers found above the tide line on many beaches Collections in ARCTOS from throughout much of the region, but only one (georeferenced) collection from the southern portion, and none from the southern outer islands. (Collections appear to be infrequent through much of BC before becoming common again in coastal Washington and Oregon.)
Lathyrus ochroleucus	Cream pea	A single (not georeferenced) collection from Hyder in ARCTOS (see link below) originally identified as L. venosus (and included in Hulten as such), but later changed to L. ochroleucus. The overall range of this species appears to be well east of the coast range, so it is unclear what to make of the Hyder collection.
Lathyrus palustris	Marsh Pea	Collections in ARCTOS throughout from north to south, mostly from the mainland or near by islands. A single collection from Baranof Island.
Lotus corniculatus	Bird's-foot Trefoil	A number of records in AKEPIC, mostly from islands in the vicinity of the Stikine River delta, but also from Prince of Wales. In addition, ARCTOS has a collection from Hoonah.
Lupinus arcticus	Arctic lupine	Apparently no collections of this species from Southeast Alaska in ARCTOS. Hulten includes a collection record from Juneau and maps the species as occurring in the northeastern part of the region. (It is presumably Hulten's map that led to the inclusion of this species in subsequent treatments.) There are collections from the BC side of the border. If this species occurs it is either overlooked due to similarity to the common Nootka Lupine (Lupinus nootkatensis), or only occurs at the margins of the region.
Lupinus kuschei	Yukon Lupine	Collections in the Haines triangle of BC not far from the border, but so far not known from Southeast Alaska. (If it does occur, it would most likely be along the Alsek River, where it has been found a few miles east of the border.)
Lupinus lepidus	Pacific lupine	Included in the preliminary checklist, probably on the basis of a mapped occurrence from the extreme southeastern part of the region included in Hulten's Flora of Alaska. Mapped records from BC all appear to be from very near the southern border, which suggests Hulten's record may have been a mistake.
Lupinus nootkatensis	Nootka Lupine	Large herb with blue pea flowers and roundish deeply lobed leaves found along roadsides, and in estuary and upper elevation meadows. Collections in ARCTOS from around the region.
Lupinus polyphyllus	Large-leaf lupine	A few collections in ARCTOS from the southern part of the region, and the very northern part of the region. Many additional reports in AKEPIC database, mostly from the same areas.
Medicago lupulina	Black Medick	Few collections in ARCTOS (though on from 1958 in Sitka). AKEPIC has many reports, mostly from Prince of Wales Island, but also Sitka, Ketchikan, Juneau, and Kake.
Medicago minima	Alfalfa	In AKEPIC database, four 2004 records from Prince of Wales Island. The observer suggested it may have been part of seed mix. Not considered established in British Columbia, it is probably also not established in Southeast Alaska.
Medicago polymorpha	Burr Clover	Apparently no recent records. AKEPIC notes this species was reported in Anderson's 1918 "Plants of southeastern Alaska" as "Common weed in Sitka."
Medicago sativa	Alfalfa	A single 1926 collection from Juneau in ARCTOS, and two reports from near Klawock (2005, 2006) in AKEPIC. It is unclear whether this species is established is in the region.
Melilotus alba	White Sweetclover	Reports in AKEPIC database from Haines, Skagway, Juneau, Hoonah, Kake, the Stikine River area, Prince of Wales, and Metlakatla.
Melilotus officinalis	Yellow Sweetclover	Records in AKEPIC database from Prince of Wales Island, Petersburg, Juneau, and Haines.
Oxytropis borealis	Boreal Locoweed	Included on the preliminary checklist based on map in Hulten. However, there are no records from the region, with the nearest being just north of the Yukon border. It probably does not occur in Southeast Alaska.
Oxytropis campestris	Field Locoweed	Small light yellow flowered legume of gravel bars and rocky areas at upper elevations Collections in ARCTOS from throughout much of the region, though more concentrated along northern mainland.
Oxytropis deflexa	Nodding Locoweed	No georeferenced collections in ARCTOS from the region, though there is an e-Flora BC collection mapped from near the border on Alsek Lake. Hulten has a collection mapped from the border area north of Skagway. Given the overall distribution of this species, it is likelly to occur only at the northern margins of Southeast Alaska, if at all.
Oxytropis huddelsonii	Huddelson's Locoweed	Apparently no collections from Southeast Alaska, there are several records from the Haines triangle of British Columbia, though non especially near the border.
Oxytropis maydelliana	Maydell's Locoweed	Apparently no collections from the region in ARCTOS, but Hulten indicates a collection from near the border along the Taku River. E-flora BC has a couple of collections mapped from the Haines triangle.
Oxytropis nigrescens	Blackish Oxytrope	Apparently no collections from Southeast Alaska, but this species has been found very near the border from nunataks in the Juneau Icefield on the Canadian side.
Oxytropis scammaniana	Scamman's Oxytrope	No collections in ARCTOS from the region, and only a single record mapped on e-Flora BC in British Columbia adjacent to the border with Yukon Territories. Hulten indicates an isolated collection from the area of the Juneau ice field.
Oxytropis splendens	Showy Locoweed	A single record from the Haines triangle indicated on the e-Flora BC maps is the only one particularly close to Southeast Alaska.
Trifolium aureum	Field Clover	Reported in AKEPIC database from Kupreanof and Prince of Wales Islands. One collection from Kupreanof Island in ARCTOS.
Trifolium campestre	Field Clover	Reported as being introduced to Juneau (check Hulten?) - no records of this species in AKEPIC. (check T. aureum)
Trifolium dubium	Suckling Clover	Four scattered reports in AKEPIC database, one from 1941 in Juneau, others from False Island (1997), Prince of Wales Island (2005), and Kosciusko Island (2007).
Trifolium hybridum	Alsike Clover	Only a couple of collections in ARCTOS, but many reports in the AKEPIC database from across most of the region.
Trifolium pratense	Red Clover	Introduced species with many records in AKEPIC from human impacted areas throughout the region.
Trifolium repens	White Clover	Intoduced species with reports in AKEPIC database for throughout the region almost wherever there has been significant human habitation or impact over the past 100 years.
Trifolium wormskioldii	Coast Clover	Included in the preliminary checklist, Hall's 2010 treatment - presumably both based on a single record Hulten has mapped from what appears to be Annette Island. There are no collections in ARCTOS. E-flora BC has mapped records from Haida Gwaii, which appear to be the nearest reports (other than Hulten) to Southeast Alaska.
Vicia americana	American Vetch	Apparently three collections in ARCTOS from Southeast Alaska, two from the mainland (Taku River, and Hyder, not georeferenced), plus one from Coronation Island.
Vicia cracca	Bird Vetch	One collection from Hyder in ARCTOS. A handful of reports in AKEPIC database from Prince of Wales, Hyder, Juneau, and Skagway.
Vicia nigricans	Giant Vetch	Collections in ARCTOS from as far north as Douglas Island (not all of them georeferenced).
Vicia sativa	Garden Vetch	Only report from early 1900s in Sitka. This species is probably not established in the region.

Gentianella propinqua	Four-parted Dwarf Gentian	Collections in ARCTOS from the northern mainland, Chichagof Island, and Coronation Island.
Gentianella tenella	Slender gentian	No georeferenced records in ARCTOS from the region. Hulten indicates an isolated occurrence in the vicinity of Juneau. A photo record from Bear Mountain on Baranof Island is the only other record [3]
Lomatogonium rotatum	Marsh Felwort	Collections in ARCTOS from northern Admiralty Island and on either side of Lynn Canal.
Swertia perennis	Bog Swertia	Collections in ARCTOS mostly from the outer islands and the vicinity of Glacier Bay, but also a few near Juneau.

Geraniaceae (Geranium: 6 species)

Scientific Name	Common Name	Summary
Erodium cicutarium	Red-stem Stork-bill	This species is considered one with invasive tendencies. Only reported from Juneau, with old collections (from 1920s) and one collection from 2004 in ARCTOS. No other records in AKEPIC.
Geranium bicknellii	Bicknell's Cranebill	A single collection in ARCTOS from Juneau. AKEPIC includes this species in the introduced plants database, though e-Flora BC indicates it is native in British Columbia.
Geranium carolinianum	Carolina Cranebill	A single collection in ARCTOS from Juneau with no recent records. This species is probably not established in Southeast Alaska.
Geranium erianthum	Northern Stork-bill	Fairly Common perennial herb on well-drained meadows from the beach to subalpine. Georeferenced collections in ARCTOS are mostly from the northern mainland, but also from Baranof, Coronation, and Prince of Wales Islands.
Geranium robertianum	Herb Robert	Few collections in ARCTOS, but reports from several communities in the region in AKEPIC database.
Geranium sanguineum	Bloody Geranium	Two collections in ARCTOS (1936 and 1948) from the Pioneer Home Garden in Sitka (where it had apparently been moved from its initial location at Sawmill Cove). No other reports in AKEPIC.

Grossulariaceae (Currant: 7 species)

Scientific Name	Common Name	Summary
Ribes bracteosum	Stink Currant	Collections from throughout the region, though few on the northern mainland. PacNW endemic
Ribes glandulosum	Skunk Currant	Four collections in ARCTOS from 2011 and 2012, two in Taku Inlet, one from the Juneau Icefield, and one from Dall Island. Yakobi Island record reported by Hall does not appear to be in ARCTOS or PacNW herbaria database. Additional records along the Stikine River just across the border.
Ribes hudsonianum	Northern Black Currant	Although a number of Trailing Black Currant (Ribes laxiflorum) collections show up in an ARCTOS search for this taxon, it appears the only collections identified as this species from the region are near Skagway and Hyder.
Ribes lacustre	Prickly Currant	Collections in ARCTOS from across much of the region, though they tend to be clustered a bit. Whether this reflects the distribution, or is merely an artifact of effort, is not clear.
Ribes laxiflorum	Trailing Black Currant	Collections in ARCTOS from throughout the region (though none georeferenced from Chichagof Island, where it no doubt occurs).
Ribes oxyacanthoides	Canada Gooseberry	Seems unlikely to occur, nearest records are from well inland in British Columbia.
Ribes triste	Red Swamp Currant	Two Georeferenced collections in ARCTOS from upper Lynn Canal (Takhin Valley, and at Dyea).

Haloragaceae (Water Milfoil: 4 species)

Scientific Name	Common Name	Summary
Myriophyllum alterniflorum	Alternate-flowered Water-milfoil	Although included by Hall in her 2010 treatment, there are no records from Alaska in ARCTOS. On the other hand, the FNA map does show Alaska in the range (but not Yukon Territory nor British Columbia). Most of the overall range appears well away from Alaska, so whether this species occurs in the region is unclear. It's possible Hall's note was intended to refer to Alternate-flowered Water-milfoil (Myriophyllum farwellii), which is known from few widely disjunct locations in Alaska.
Myriophyllum farwellii	Alternate-flowered Water-milfoil	Collection from Lake Eva on Baranof Island
Myriophyllum sibiricum	Shortspike Watermilfoil	Only four collections in ARCTOS from the region, all from the northern parts, including Chichagof Island, Haines, Juneau, and Glacier Bay (this one not georeferenced).
Myriophyllum verticillatum	Whorl-leaf Water-milfoil	Only a handful of collections in ARCTOS, from near Yakutat, Haines (not georeferenced), and the Stikine River mouth.

Hippuridaceae (Mare’s Tail: 3 species)

Scientific Name	Common Name	Summary
Hippuris montana	Mountain Mare's-tail	Inconspicuous species of wet subalpine and lower alpine meadows. Probably Fairly Common. A few scattered collections in ARCTOS from throughout the region.
Hippuris tetraphylla	Four-leaf Mare's-tail	Only four collections in ARCTOS, three from the vicinity of the Stikine River mouth, the other from Chichagof Island.
Hippuris vulgaris	Common Mare's-tail	Collections in ARCTOS from scattered throughout the region.

Hydrophyllaceae (Waterleaf: 6 species)

Scientific Name	Common Name	Summary
Nemophila menziesii	Baby Blue Eyes	No collections in ARCTOS, and no records from AKEPIC, so this species may not be established in the region.
Phacelia franklinii	Franklin's Phacelia	Apparently no geoferenced collections in ARCTOS, but Hulten includes a dot from the vicinity of Skagway in the occurrence map for this species.
Phacelia mollis	Soft Phacelia	A single collection in ARCTOS from Haines (1949).
Phacelia sericea	Silky Phacelia	Four collections in ARCTOS, apparently all from near the same location 14 miles up the Haines Highway. No other records within hundreds of miles (with the greater part of this species' distribution much to the south, but a few occurrences north in the Yukon and eastern Alaska.)
Romanzoffia sitchensis	Sitka Mist-maiden	Collections in ARCTOS from throughout the region.
Romanzoffia unalaschcensis	Unalaska Mistmaiden	Only three collections in ARCTOS from the region, all from the outer coast.

Lamiaceae (Mint: 16 species)

Scientific Name	Common Name	Summary
Clinopodium douglasii	Yerba Buena	Included on the preliminary checklist based on an early report from Juneau. That appears to be the only record of this species in the state.
Dracocephalum parviflorum	Dragonhead	Included in the preliminary checklist, but no collections in ARCTOS from anywhere close to Southeast Alaska. This species appears to be distributed primarily well inland.
Galeopsis bifida	Split-lip Hemp-nettle	Collections in ARCTOS and reports in AKEPIC database from multiple communities in the region.
Galeopsis tetrahit	Brittle-stem Hemp-nettle	A handful of collections in ARCTOS with many records from several communities throughout the region.

Lycopus uniflorus	Northern Bugleweed	Several collections from the southern half of the region (Stikine River and Prince of Wales Island south), with a single collection from northern Chichagof Island.
Marrubium vulgare	Horehound	A single 1927 collection from Juneau which notes that it was introduced with sheep manure. No further records in AKEPIC, so this species was presumably never established.
Mentha arvensis	Field Mint	Scattered collections from the mainland (north to south) and the southern islands. No collections from the major central and northern islands.
Mentha spicata	Spearmint	A single 1979 collection in ARCTOS from Goddard Hot Springs (near Sitka). An old (first half of 1900s) report from Juneau and a 2014 report from northern Prince of Wales Island in AKEPIC.
Mentha x piperita	Peppermint	A single early (<1918) report noted in AKEPIC database from Juneau. Probably not established in the region outside of where it has been planted.s

Scientific Name	Common Name	Summary
Pinguicula villosa	Hairy Butterwort	Only four collections in ARCTOS, two from Sitka (1958 and 2004), one from Douglas Island (1962), and one from Revillagigedo Island (1963).
Pinguicula vulgaris	Common Butterwort	30+ Collection in ARCTOS from throughout the region (though some gaps - such as no georeferenced collections from Admiralty Island).
Utricularia intermedia	Flat-leaf Bladderwort	A few scattered collections in ARCTOS spanning the region.
Utricularia macrorhiza	Common Bladderwort	Apparently no collections in ARCTOS from the region, though Hulten has marks near Haines and Annette Island.
Utricularia minor	Lesser Bladderwort	Only a few collections, all from the Stikine River south on the mainland or near islands.

Linaceae (Flax: 1 species)

Scientific Name	Common Name	Summary
Linum lewisii	Blue Flax	Hall includes L. perenne it in her 2010 treatment (which is otherwise almost exclusively native species). L. lewisii has been considered a subspecies of this Eurasian species, so we presume this is the one she was referring to. In either case, there are no records from Southeast Alaska in ARCTOS.

Malvaceae ( 1 species)

Scientific Name	Common Name	Summary
Sidalcea hendersonii	Henderson's Checker-mallow	A single collection from near Pt. Howard (west of Juneau) in 2003 is apparently the only record of this species north of Vancouver Island in southern BC. Origination status is unknown. Subsequent visits to the site did not turn up additional plants (Kitty LaBounty pers. comm), so it should not be considered established in the region.

Menyanthaceae (Buckbean: 2 species)

Scientific Name	Common Name	Summary
Menyanthes trifoliata	Buckbean	Collections in ARCTOS from across the region (though only one after 1993).
Nephrophyllidium crista-galli	Deer Cabbage	Common ground cover of upper elevation open areas with succulent kidney-shaped leaves. Also found somewhat less abundantly in some lower elevation muskegs. Collections from throughout the region.

Myricaceae (Bayberry: 1 species)

Scientific Name	Common Name	Summary

Nymphaeaceae (Water Lily: 3 species)

Scientific Name	Common Name	Summary
Nuphar polysepala	Yellow Pond-lily	Common aquatic plant of shallow lake margins and bog ponds with round floating leaves and large showy yellow flowers. A few collections spanning the full region, though significant gaps (presumably due to lack of collecting effort rather than absence).
Nymphaea odorata	Fragrant Waterlily	Known from a single pond in Indian River valley. There is evidence to suggest that its presence is due to a planting by E. W. Merrill in the early 1900s.
Nymphaea tetragona	Pygmy Waterlily	Only two collections from the region in ARCTOS, both from the southern portion on islands near the mainland.

Onagraceae (Evening-primrose: 12 species)

Epilobium anagallidifolium	Alpine Willowherb	Collections in ARCTOS scattered across the region, though apparently none (that are georeferenced) from the northern islands. The taxonomy of this species is unclear - ARCTOS considers Epilobium alpinum a synonym, while The Plant List does not.
Epilobium ciliatum	Glandular Willow-herb	Collections in ARCTOS from throughout the region.
Epilobium davuricum	Northern Swamp Willowherb	A single collection from the St. Elias mountains between Yakutat Bay and Icy Bay.
Epilobium hornemannii	Hornemann's Willow-herb	Scattered collection in ARCTOS from across the region. Fewer on the outside islands.

Orobanchaceae (Broomrape: 22 species)

Scientific Name	Common Name	Summary
Boschniakia hookeri	Vancouver groundcone	Closest records mapped in e-Flora BC are from southern Haida Gwaii.
Boschniakia rossica	Northern Ground-cone	Fairly Common parasitic plant associated with Sitka alder. Southeast Alaska may represent the southern extent of the range of this species west of the coast range. Collections in ARCTOS throughout much of the region, except the far southern parts. (No collections from further south along the coast in BC are indicated in e-flora BC.)
Castilleja hyperborea	Northern paintbrush	No collection in ARCTOS from the region. There are several collections from the Haines triangle area of British Columbia, the overall distribution of this species makes it seem unlikely to occur on the coastal side of the coast mountains.
Castilleja miniata	Giant Red Paintbrush	Many collections from the region in ARCTOS. (Seems to be absent from Sitka Sound and the west side of Baranof Island.)
Castilleja pallida	Green Paintbrush	Included in Hall's 2010 treatment, there are apparently no collections in ARCTOS from the region - Hulten has C. caudata from southwestern Yukon Territory north.
Castilleja parviflora	Mountain Paintbrush	Common perennial herb with showy magenta bracts found in subalpine and alpine meadows at or above treeline. Collections in ARCTOS mostly from the northern mainland but also some scattered throughout the rest of the region.
Castilleja tenuis	Hairy Indian Paintbrush	Reported from Skagway in the first half of the 1900s. No more recent reports of this introduced species - it is presumed to not be established. It is native to British Columbia, but limited to the far southern portion.
Castilleja unalaschcensis	Alaska Paintbrush	Perennial herb with simple, linear leaves and showy yellow bracts that is common in well drained meadows from sea level to the treeline. Many collections in ARCTOS, especially from the outer coast and the northern mainland. Pacific Northwest (southern BC to closest Aleutian Islands) endemic.
Euphrasia mollis	Subalpine Eyebright	Small plant which is easy to overlook. It may be more common than currently thought. Several collections in ARCTOS from the northern mainland and outer islands.
Euphrasia nemorosa	Common Eyebright	Collections in ARCTOS and reports in AKEPIC database, primarily from upper Lynn Canal and the southern half of the region. Also from Juneau and Yakutat.
Euphrasia subarctica	Arctic Eyebright	A handful of collections in ARCTOS, mostly from the northern mainland (with several in the database as E. disjuncta). A single record from Chichagof Island.
Pedicularis capitata	Capitate Lousewort	Three collections in ARCTOS between upper end of Lynn Canal and the Canadian border.
Pedicularis labradorica	Labrador Lousewort	No georeferenced collections in ARCTOS from the region. Eflora BC has collections indicated from just across the border along the Haines Highway.
Pedicularis lanata	Wooly Lousewort	There are few collections/reports of this species from the region; most (all?) from the southern islands (Dall Island, Revillagigedo Island, and Prince of Wales Island). Given the relatively isolate occurrence of this species on the southern Southeast Alaska islands and Haida Gwaii (as opposed to much more continental distribution in the rest of BC - with the nearest other coastal collection well to the north at the Malaspina forelands), it may be worth investigating whether this coastal population shows genetic evidence of isolation during the last ice age.
Pedicularis langsdorfii	Langsdorf's Lousewort	No collections georeferenced in ARCTOS from the region. There are several collections from the Haines Triangle of BC mapped on the e-Flora BC atlas.
Pedicularis macrodonta	Muskeg Lousewort	Only one collection in ARCTOS of this species. It has been considered a subspecies of Small-flowered Lousewort (Pedicularis parviflora) and it may be that some collections labeled under that name are of this species.
Pedicularis oederi	Oeder's Lousewort	Scattered (georeferenced) records from across the region in ARCTOS. Additiona collections from the region may be in the non-georeferenced records.
Pedicularis ornithorhyncha	Duck's Bill Lousewort	Collections in ARCTOS are all from the southern inside islands and mainland or Baranof Island. Apparently reaches the northern extent of its range in Southeast Alaska. Pacific Northwest Coast endemic.
Pedicularis parviflora	Small-flowered Lousewort	Collections in ARCTOS primarily from the northern half of the region. It appears this species may reach its southernmost extent on the west coast of North America in Southeast Alaska.
Pedicularis sudetica	Sudet Lousewort	Collections in ARCTOS from Juneau area and near Skagway, plus several in the vicinity of Yakutat.
Pedicularis verticillata	Whorled Lousewort	Collections in ARCTOS are mostly from the west side of the outermost islands. There are also collections from near Juneau and Skagway. This species appears to reach its southern extent along the west coast on Haida Gwaii. Possible refugial candidate (with primary population present in the north and recolonizing southward from there)?
Rhinanthus minor	Rattlebox	Most georeferenced collections in ARCTOS from the northern half of the region. One collection from Prince of Wales is the only from the south of the Sitka area.

Papaveraceae (Poppy: 7 species)

Papaver lapponicum	Lapland Poppy	Collection from the Haines triangle in BC. Given the overall distribution of this species, if it occurs, it is probably only at the very margins.
Papaver macounii	Macoun's Poppy	No georeferenced collections in ARCTOS from the region. The FNA map suggests this species range southeastern boundary sweeps down from southern Yukon territory to the Alaskan coast near Prince William Sound.
Papaver mcconnellii	McConnell's Poppy	Three 2004 collections from Chichagof Island in ARCTOS are the only records of this species in the region. They were collected from areas with limestone and represent significant range extensions.
Papaver radicatum	Alpine Poppy	A single collection from Baranof Island is all that is georeferenced in ARCTOS under this species. Additional records from just across the border in British Columbia are indicated on the eFlora BC map. There is a Bear Mountain (Baranof Island) Papaver collection not identified to species. See also McConnell's Poppy (Papaver mcconnellii)

Found on stable gravel bars and mountain rills, until recently known primarily from several watersheds on Baranof Island and near Hyder in Southeast Alaska with a single collection from Admiralty Island. In 2013 it a single plant was found along Rust Lake Creek on Chichagof Island and "hundreds of individuals" were at Lake Stanton(?) near Farragut Bay (per K. Dillman via K. LaBounty). Over half the collections from the region in ARCTOS are from Baranof Island, but there are also collections from Chichagof, Admiralty Island, and the mainland at Taku Inlet, Stanton Lake (central part of mainland), and from the vicinity of Hyder.

Primulaceae (Primrose: 9 species)

Scientific Name	Common Name	Summary
Androsace lehmanniana	Sweet-flowered fairy-candelabra	Four collections in ARCTOS, all from the southern outer islands. The Southeast Alaska records appear to be hundreds of miles from any others. Is this evidence of a population that survived in a glacial refugia during the last ice age?
Androsace septentrionalis	Pygmyflower rockjasmine	No collections of this species in ARCTOS from the region. Hulten indicates collections form near the northern border (though resolution of the map is insufficient to tell which side they are on).
Dodecatheon frigidum	Northern shooting star	Less than a handful of collections georeferenced in ARCTOS from the northern mainland (mountains at the north end of Lynn Canal), plus one (1959) outlying record from Woronkofski Island alpine.
Dodecatheon jeffreyi	Tall Mountain Shooting-star	Perennial herb with sweet smelling flowers frequent in bogs at mid to upper elevations and fen-like muskegs at lower elevations. Collections in ARCTOS from across much of the region, though most are from the outer coast.Collections also from the southern inner islands and Juneau.

Has also been found at higher elevation meadows around Juneau, Takhin ridge west of Haines, and at least once on NW Chichagof Island. (Associated with calcareous at upland sites?) Collections in ARCTOS from throughout the region.
Primula cuneifolia	Wedge-leaf Primrose	Small herb of dry subalpine tundra that is easily overlooked when not in bloom.

Primula egaliksensis	Greenland Primrose	Collections in ARCTOS from northern mainland including Taku Inlet, Haines, Gustavus, and Yakutat.
Primula incana	Silvery Primrose	Apparently no collections of this species from the region in ARCTOS. FNA indicates Alaskan records of P. stricta (an eastern NA species) should be P. incana, P. avilensis, or P. borealis. P. incana is the only one with records from anywhere close to Southeast Alaska (southern Yukon, and interior BC). Hulten has a record of P. stricta from near the border (difficult to say which side) between Haines and Skagway.
Primula pumila	Arctic Primrose	Only three collections from the region in ARCTOS, all west Chichagof Island (Whitestripe Lake and Rust Lake). Also known from Starrigavan Ridge on Baranof Island.

Aquilegia brevistyla	Blue Columbine	FNA Range map indicates that this species barely gets into southeast. No collections in ARCTOS of this species. Hulten indicates a collection record from the vicinity of Skagway. The overall distribution of this species seems distinctly continental.
Aquilegia flavescens	Yellow Columbine	A single collection in ARCTOS from a tributary creek of the lower Taku River. This observation appears to be well outside the expected range for this species.
Aquilegia formosa	Columbine	Fairly common plant of open places, including beach meadows, road sides, gravel bars, and subalpine meadows. Collections in ARCTOS from across the region.
Caltha leptosepala	Mountain Marsh-marigold	Uncommon plant of wet subalpine or alpine meadows. Collections in ARCTOS from across the region (with some gaps).
Caltha natans	Floating Marsh-marigold	Although Hall included this species in her treatment, the FNA range map does not show it occurring near Southeast Alaska. There are no (georeferenced) records of this species in ARCTOS from within a couple of hundred miles of the region.
Caltha palustris	Yellow Marsh-marigold	Collections in ARCTOS from across the region, though mostly from the northern mainland and southern inside areas. No (georeferenced) collections from Admiralty or Baranof Islands, and only one each from Prince of Wales and Chichagof Islands.
Coptis aspleniifolia	Fern-leaf Goldthread	Locally abundant wintergreen herb of open forest areas. Flowers are present relatively early, and are easy to overlook. Leaves are not always present at the time of blooming. Collections (georferenced) in ARCTOS from much of the region, though none from the gulf coast nor from Prince of Wales Island. Pacific Northwest coastal endemic (southern BC to Southcentral Alaska).
Coptis trifolia	Three-leaf Goldthread	Common small herb with shiny tri-partite leaves found in muskegs. Collections in ARCTOS from across the region, though few from the outside islands.
Delphinium glaucum	Glaucous Larkspur	Two (georeferenced) collections in ARCTOS, both from the mainland between Haines and the border with Canada.
Pulsatilla patens	Pasque flower	No reports of this species collections in ARCTOS from the region, though e-Flora BC maps indicate records from not far across the border north and east of Lynn Canal.
Ranunculus abortivus	Littleleaf Buttercup	A single 1940 collection (on two sheets) made in/around Juneau is the only record from the region in ARCTOS. Given the lack of subsequent records, and the primary range (Rocky Mountains and east though there is a disjunct population on the Kenai Peninsula) this species may not be established in the region.
Ranunculus acris	Tall Buttercup	Apparently only a few collections from the region (ARCTOS), there are many reports from communities across the region in AKEPIC database.
Ranunculus aquatilis	Water Crowfoot	Collections in ARCTOS from southern Southeast Alaska, Chichagof Island, one collection from northern Baranof Island, one collection from upper Lynn Canal, and collections from the Yakutat area.
Ranunculus cooleyae	Cooley's Buttercup	Most common buttercup in subalpine/alpine meadows. Though most sources do not indicate it, this species is also found less commonly at lower elevations. The pattern of distribution at lower elevations is not entirely clear, but it seems fast moving streams - perhaps restricted to locations where cold and/or snowy winters are the norm. Collections from across the region in ARCTOS, though only from the far southern mainland in the southern half. Pacific Northwest Endemic (primarily coastal)
Ranunculus cymbalaria	Shore Buttercup	Scattered collections in ARCTOS from across the region, with the only collections from the outer coast in the area of Yakutat. (A single collection from Sitkoh Bay on the east side of Chichagof Island is the only one from the outer islands.)

Ranunculus gelidus	Wetslope Buttercup	All though included on the preliminary checklist and included in Hall's 2010 treatment, there appear to be no collections in ARCTOS from the region. The closes collections indicated in eFlora BC are from the continental side of the coast range.
Ranunculus gmelinii	Small Yellow Water-buttercup	A single collection in ARCTOS from Farm Island in lower part of the Stikine River.
Ranunculus hyperboreus	Arctic Buttercup	A single (georeferenced) collection in ARCTOS from the region at White Pass outside of Skagway. E-flora BC indicates a collection from BC near the border along the Haines highway.
Ranunculus lapponicus	Lapland Buttercup	No collections in ARCTOS from the region, but Hulten indicates a record from near White Pass (though it may be in BC).
Ranunculus macounii	Macoun's Buttercup	Only two collections in ARCTOS from the region, one on Prince of Wales, one from the Taku River.
Ranunculus nivalis	Snow Buttercup	Primarily a species from the interior side of the coast range. Collections in ARCTOS from near the border north of Skagway, as well as Chichagof Island, Dall Island, and on the Bradfield Peninsula. sepals have reddish hairs
Ranunculus occidentalis	Western Buttercup	varieties in the region? per FNA, perhaps brevistylis/occidentalis and nelsonii? Plants with many extra petals have been found on Kruzof Island, but subspecies hexasepalus said to be restricted to Haida Gwaii. Collections in ARCTOS from across the region. Though few collections from Prince of Wales and the northern gulf coast. Check beak of achenes (even immature); this species should have curved beaks
Ranunculus orthorhynchus	Straight-beak Buttercup	A few collections in ARCTOS, most from the southern part of the region, with one from the Juneau area. FNA distribution map indicates the northern edge of the range of this species is expected to be in Southeast Alaska.
Ranunculus pacificus	Pacific Buttercup	Endemic to Southeast Alaska. Collections in ARCTOS from Yakutat south to northern Prince of Wales Island and Noyes Island (including inside locations as well). Beaks of achenes should be straight
Ranunculus pedatifidus	Northern Buttercup	Included in the preliminary checklist, there are no collections of this species from the region in ARCTOS. The nearest collection indicated in eFlora BC is near Carcross in Canada, north of Skagway.
Ranunculus pensylvanicus	Pennsylvania Buttercup	Included in the preliminary checklist based on a report from Ketchikan and from Juneau in Hulten. FNA distribution map includes much of Southeast Alaska, but there are no collections from the region (nor anywhere especially close) in ARCTOS.
Ranunculus pygmaeus	Pygmy Buttercup	A single georeferenced collection in ARCTOS from the region in the vicinity of White Pass. One (as yet unconfirmed) report (with photo) from Baranof Island.
Ranunculus repens	Creeping Buttercup	Collections in ARCTOS and/or reports in AKEPIC from across the region where there has been significant human impact.

Thalictrum occidentale	Western Meadowrue	FNA map indicates much of Southeast Alaska is included in the range, though collections in ARCTOS are all from Prince of Wales Island or from Hyder. Species to check for evidence of persistence in refugia during past ice age?
Thalictrum sparsiflorum	Few-flowered Meadowrue	Collections in ARCTOS from the mainland, primarily from Juneau northward, but also one from the Stikine River mouth.
Thalictrum venulosum	Veiny Meadowrue	No collections in ARCTOS, but FNA map indicates range could include areas north of Skagway in the vicinity of White Pass.

Rosaceae (Rose: 56 species)

Scientific Name	Common Name	Summary
Alchemilla glabra	Smooth Lady's-mantle	Collection in ARCTOS from Neka Bay near Hoonah (1979) is listed as this species. FNA treatment indicates this species occurs in Alaska. The 1979 collection is also included under Hairy Lady's Mantle (Alchemilla monticola) and A. subcrenata in the eFlora BC mapping. Possibly because the collection was originally identified as A. vulgaris, which is considered a synonym of both of those species as well. (See FNA account for Alchemilla). The FNA distribution information for each of those species does not include Alaska, though A. monticola has an additional report from Sitkine River in AKEPIC database (other records there are under Alchemilla mollis)
Alchemilla monticola	Hairy Lady's Mantle	In ARCTOS no collections currently named as this species, though 1979 Neka Bay collection is there as Smooth Lady's-mantle (Alchemilla glabra) Reports in AKEPIC from Stikine River mouth (2002) and Neka Bay (1979), Chichagof Island, near an abandoned cabin (presumably referable to the ARCTOS collection). FNA distribution information for this species does not include Alaska.
Amelanchier alnifolia	Saskatoon serviceberry	A few scattered collections from the eastern part of the region, including Hyder, Etolin Island, Wrangell Island, Admiralty Island, Chichagof Island, and upper Lynn Canal.
Aruncus dioicus	Goat's Beard	Common roadside plant with pinnately compound toothed leaves and white plume-like flowers. Also found along streams, meadows, and forest edges. Collections in ARCTOS spanning the region, though there are gaps such as the southern outer islands and Chichagof Island.
Comarum palustre	Purple Marshlocks	Uncommon species of lake edges. Scattered collections in ARCTOS from across the region. (Many collections of this species in ARCTOS are not georeferenced, and there may be additional collections from the region among them.)
Crataegus douglasii	Black Hawthorn	A single 1939 collection identified as suspecies suksdorfii is the only one in ARCTOS. A collection from Juneau area originally labeled as this species was later identified as Pacific Crabapple (Malus fusca). FNA treats C. d. suksdorfii as C. gaylussacia and in the range information does not list Southeast Alaska, but does say it occurs in the vicinity of Anchorage. FNA range information for C. douglasii indicates it occurs in 'panhandle of Alaska' Given the lack of collections and apparently conflicting information, it's not clear which species should be expected in the region, nor the extent to which they occur.
Dasiphora fruticosa	Shrubby Cinquefoil	Only two mapped collections in ARCTOS from the region. One from the border area along the Alsek River, the other near the border at White Pass (Skagway).
Dryas alaskensis	Alaska Mountain-avens	A few collections mapped in ARCTOS from the northern part of the region from near Haines and Skagway to the border. Taxonomy is a little unclear for collections from the region, consider also Hooker's Mountain-avens (Dryas hookeriana). D. octopetala is now considered to be restricted to Greenland [4].
Dryas drummondii	Drummond's Mountain-avens	Most georeferenced collections in ARCTOS from upper Glacier Bay and upper Lynn Canal. Also collections from southern outer islands (Coronation Island, northern Prince of Wales Island, and Dall Island). A single collection from near Hoonah. Candidate for refugial relict in the south?
Dryas hookeriana	Hooker's Mountain-avens	A few collections mapped in ARCTOS from the northern part of the region from near Haines and Skagway to the border. Taxonomy is a little unclear for collections from the region (consider also Alaska Mountain-avens (Dryas alaskensis). D. octopetala is now considered to be restricted to Greenland.

Potentilla gracilis	Slender Cinquefoil	Collections in ARCTOS from near Haines, Skagway, and Juneau.
Potentilla hippiana	Wooly Cinquefoil	No collections in ARCTOS of this species. Alaska is not included in range of this species in FNA account. Hulten has dots from Stikine and Alaska Range, but indicates no specimens were looked at prior to publication.
Potentilla hookeriana	Hooker's Cinquefoil	The FNA treatment of this species does not have it occurring in Alaska. Prior records that had been treated as this species are considered by the FNA authors to be Snow Cinquefoil (Potentilla arenosa).
Potentilla nana	Arctic Cinquefoil	A single collection from Revillagigedo Island identified as this species in ARCTOS. Additional records show up in a search for this species, but with the name P. hyparctica. See FNA account for discussion of how this species relates to P. hyparctica.

Scientific Name	Common Name	Summary
Galium aparine	Cleavers	Common along many beaches. Collections in ARCTOS from across the region.
Galium boreale	Northern bedstraw	No mapped collections in ARCTOS from the region, e-Flora BC has two records from very close to the Alaskan border outside of Haines and Skagway. If it occurs in the region, it is probably only at the margins.

Galium trifidum	Small Bedstraw	Collections in ARCTOS from across the region.
Galium triflorum	Sweet-scented Bedstraw	Collections in ARCTOS from across the region.

Salicaceae (Willow: 29 species)

Scientific Name	Common Name	Summary
Populus balsamifera	Balsam Poplar	Unclear whether this species occurs in Southeast Alaska. ARCTOS herbarium records are all of Populus balsamifera ssp. trichocarpa (Populus trichocarpa) and it seems plausible that this species is restricted to interior regions of BC into Yukon and Alaska - not reaching the coast before South Central Alaska.
Populus tremuloides	Quaking Aspen	Just two collections mapped from the region in ARCTOS,one from outside of Haines and the other outside of Skagway.
Populus trichocarpa	Black Cottonwood	Collections in ARCTOS from the across all but the far southern mainland. Also from Chichagof and Baranof Islands.

Salix arbusculoides	Littletree Willow	Mid sized shrub or tree with narrowly elliptic leaves and leaf-like stipules Reported to occur in the region, there are no georeferenced collections of this species in ARCTOS or on the eFlora BC map.
Salix arctica	Arctic Willow	Dwarf shrub with erect or trailing branches Collections in ARCTOS from across the region.
Salix barclayi	Barclay's Willow	Shrubs to 6ft tall, leaf out and flowering co-occur Collections in ARCTOS primarily from the mainland and smaller islands of the Stikine River delta. Also a collection from Chichagof Island.
Salix barrattiana	Barratt's Willow	Upright shrub to 2ft with often vertical leaves grey with long hairs No collections in ARCTOS mapped from the region, though Hulten includes a dot on the map near Skagway. Overall distribution of collections suggests this species is more continental, and if it occurs at all, it is probably only at the margins.
Salix bebbiana	Bebb Willow	Large shrub or small tree frequently with diamond pattern on the trunks. A single collection from the Stikine delta mapped in ARCTOS from the region.
Salix commutata	Undergreen Willow	Densely branching shrub between 3-6ft tall Collections in ARCTOS from the Glacier Bay north and west on the mainland. One collection from the BC side of the border near Hyder.
Salix fuscescens	Alaska Bog Willow	Low shrub with trailing stems No collections within the region mapped in ARCTOS. Nor any particularly close. Reported in the Preliminary Checklist and Hall's 2010 treatment as being found on Chichagof Island, Hulten does not show this species occurring in the region. It is unclear on what basis this species was included on prior lists.
Salix glauca	Grayleaf Willow	Highly variable short to tall shrub Collections in ARCTOS from Yakutat Forelands and St. Elias mountains, also from near the border outside of Skagway. Many collections on the Canadian side near the border from the Taku River north.
Salix hookeriana	Coastal Willow	Short to mid sized shrub Collections in ARCTOS from the Yakutat Forelands are the only ones from the region. (This species is also found on Haida Gwaii.)
Salix interior	Narrow-leaf Willow	Mid sized shrubs to trees found on sand bars. Spreads clonally by root shoots. Three collections in ARCTOS from the Stikine River and delta, each identified as S. interior on the sheet, but listed as S. exigua ssp interior in ARCTOS taxonomy.
Salix lasiandra	Pacific Willow	Some disagreement in taxonomy - the FNA account for S. lucida recognizes S. lasiandra as a separate species, though ARCTOS and e-Flora BC treat it as within S. lucida. Collections mapped in ARCTOS from mainland near Hyder, Stikin River, and northern Lynn Canal.
Salix myrtillifolia	Low Blueberry Willow	Low spreading shrub to 2ft, plants spreading by layering Two collections mapped in ARCTOS from near the border outside of Skagway.
Salix niphoclada	Barrenground Willow	Low to mid sized shrub No collections in ARCTOS mapped from the region. Distribution of records shown on e-Flora BC map suggests this species does not occur on the ocean side of the Coast Range in this region.
Salix planifolia	Diamondleaf Willow	Low to tall shrubs with precocious catkins Collections in ARCTOS mapped from Haines and Skagway to the northern border of the region.
Salix polaris	Polar Willow	Dwarf shrub of moist late snowfields and scree slopes Single collections mapped in ARCTOS from southern mainland and Coronation island with additional collections from the northern mainland in mountains around Lynn Canal.
Salix prolixa	Mackenzie's Willow	Medium to tall shrubs A single mapped collection in ARCTOS from Sergief Island near the Stikine River mouth. This collection seems to be an outlier from the overall distribution of this species (more southern overall, but more interior in the north)
Salix pseudomonticola	False Mountain Willow	No collections in ARCTOS from the region, though Hulten includes a dot on the border northeast of Juneau (Taku River?).
Salix pulchra	Tea-leaved Willow	Low to tall shrubs with linear leaf-like stipules and precocious flowering No mapped collections of this species from the region in ARCTOS. Closely related to Diamondleaf Willow (Salix planifolia) - see FNA notes on that species for more about where this one may be expected to occur.
Salix reticulata	Netleaf Willow	Dwarf shrub with distinct reticulate leaves Collections from ARCTOS across much of the region. Gaps may be due to lack of effort in preferred mountain habitats. Possible refugial species (cf. Haida Gwaii population and southern outer islands)?
Salix richardsonii	Richardson's Willow	Low to tall shrubs with precocious catkins A single collection mapped in ARCTOS from the margins of the region on the Malaspina Forelands. Overall distribution of this species seems to be more northerly and continental.
Salix rotundifolia	Least Willow	Dwarf shrub with erect stems No mapped collections in ARCTOS from the region. Nearest records shown are from southwest Yukon Territory. Not treated in e-Flora BC, though Hulten's map includes a dot near White Pass.
Salix scouleriana	Scouler's Willow	Tall shrubs or trees Scattered collections in ARCTOS from across the region. Distribution of collections seems to suggest this species could occur throughout the region, though there wide areas where it has not been collected.
Salix setchelliana	Setchell's Willow	Dwarf shrub endemic to Alaska, the Yukon and extreme northwestern British Columbia Several collections in ARCTOS from the Yakutat forelands.
Salix sitchensis	Sitka Willow	Mid sized shrub to tree with subprecious to coetaneous catkins. Leaves have distinctive silky hairs on undersurface Collections in ARCTOS from across the region, though relatively few on the southern outer islands.

Micranthes hieracifolia	Hawkweed-leaved Saxifrage	A 1937 collection from Mt. Roberts is the only one mapped in ARCTOS from the region. The nearest other collection appears to be from the mountains of Southwestern Yukon.
Micranthes lyallii	Red-stem Saxifrage	Collections mapped in ARCTOS spanning the region, but significant gaps, including Baranof and Admiralty Islands, and the mainland between Cleveland Peninsula and Skagway.
Micranthes nelsoniana	Heart-leaf Saxifrage	Collections in ARCTOS from across the region, though concentrated in the southern half, and the northern mainland.
Micranthes nivalis	Alpine Saxifrage	Three collections in ARCTOS, one from Admiralty Island, one from the mainland near Wrangell, and another near Haines.
Micranthes occidentalis	Western Saxifrage	Two collections in ARCTOS, one from the Taiya river near Haines, the other from Revillagigedo Island.

Micranthes reflexa	Reflexed Saxifrage	A single collection from Mendenhall Glacier is the only one in ARCTOS from the region. This species' overall distribution appears to primarily restricted to the continental side of the coast mountains.
Micranthes tolmiei	Tolmie's Saxifrage	Several collections in ARCTOS from the eastern part of the region (mainland and near islands) as far north as Juneau area.
Mitella nuda	Naked Mitrewort	No collections in ARCTOS from the region. Hulten has a single record mapped near Skagway. Records mapped in e-Flora BC are all from the continental side of the Coast Range at latitudes corresponding to Southeast Alaska.
Mitella pentandra	Alpine Mitrewort	Collections in ARCTOS from across the region
Mitella trifida	Three-tooth Mitrewort	The only record of this species from the region appears to be a 1979 collection from near Haines. This collection is hundreds of miles from the nearest other record mapped on e-Flora BC (well to the south and east, inland from Prince Rupert). Collection notes indicates many plants. Verification of the collection id is probably warranted given the outlying nature of this record.
Saxifraga adscendens	Wedge-leaved Saxifrage	A few scattered collections from the region mapped in ARCTOS including Prince of Wales Island, Hecata Island, Chichagof Island and the mainland near Haines. Associated with limestone sites in the region?

Saxifraga oppositifolia	Purple Mountain Saxifrage	Collections mapped in ARCTOS from southern islands and the mainland from Juneau north.
Saxifraga rivularis	Weak Saxifrage	Taxonomic review needed. It appears this species probably does not occur in the region as such - it appears plants that had been called this from the region are now called Pygmy Saxifrage (Saxifraga hyperborea). FNA indicates only one subspecies of this species occurs in Alaska, and it appears to be one from the arctic.
Saxifraga serpyllifolia	Thyme-leaved Saxifrage	No mapped collections in ARCTOS from the region. Hulten's map includes dots near the Taku River and White Pass that appear to be from within Southeast Alaska.
Saxifraga tricuspidata	Three-toothed Saxifrage	Collections in ARCTOS mapped from the northern mainland as far south as Juneau.

Most easily distinguished from Rosy Twistedstalk (S. lanceolatus) and Small Twistedstalk (S. streptopoides) by large size and branching stems. Collections from throughout the region.
Streptopus lanceolatus	Rosy Twistedstalk	Common herb often found on the forest floor, especially near edges where there is only moderate shading, from low to elevations to treeline. Distinguished most easily from other Clasping twistedstalks (S. amplexifolius) and Small Twistedstalk (Streptopus streptopoides) by rosy colored flowers and intermediate size without branching stems. Collections appear to be from Juneau and south in the region. Southeast Alaska may represent the northwestern most edge of the range.

Scientific Name	Common Name	Summary
Anticlea elegans	Mountain Death Camas	Three collection sights in ARCTOS from the northern mainland.
Veratrum viride	Corn Lily	Collections from across the region, though with significant gaps (perhaps due to the size of plant, it has not be collected everywhere it is found).

Orchidaceae (Orchids: 27 species)

Scientific Name	Common Name	Summary
Amerorchis rotundifolia	Roundleaf Orchid	This species has not been collected in Southeast Alaska, though there are several collections on the BC side of the border between Skagway and Whitehorse (see e-flora BC link below). However based on the collection records through out BC and Alaska, it appears this species is typically found on the landward side of the coastal mountains, so it may not occur anywhere in Southeast Alaska.
Calypso bulbosa	Fairy Slipper	Based on collections and reports, this species seems to be found almost entirely in spruce forests near shorelines, primarily on small islands (though it is abundant in locations on Kruzof Island near Sitka). One collection inland from Haines is an exception. These are presumed to be var. occidentalis though the FNA distribution map does not have this species occurring much in our region. Do our restricted coastal populations possibly show genetic evidence of separation from the rest of the species throughout the bulk of its range? A few scattered collections from the region - primarily from the islands.
Coeloglossum viride	Long-bracted Bog-orchid	A few collections, most from the northern mainland, though also collected on Chichagof Island and the central mainland. Associated with limestone?
Corallorhiza maculata	Spotted Coralroot	ARCTOS has several collection records from Southeast Alaska, though none from after 1993, most of these are likely to be C. mertensiana (formerly a subspecies of C. maculata. The distribution map in FNA suggests this species does not occur in our region, however there have been collections from the Haines area confirmed to be C. maculata.
Corallorhiza mertensiana	Mertens' Coralroot	Locally abundant and widespread in forested areas. Collections in ARCTOS mostly from the southern 2/3 of the region, but also from Haines. Probably all the collections in ARCTOS as Corallorhia maculata would now be considered this species.
Corallorhiza trifida	Northern Coral-root	Collections in ARCTOS from northern Chichagof Island and the northern mainland. Has also occurred on Baranof Island.
Cypripedium montanum	Mountain Lady's Slipper	Collections in ARCTOS from the northern mainland and one from Etolin Island. The Southeast Alaska records appear fairly disjunct from the bulk of the range - candidate for a refugial species?
Cypripedium parviflorum	Greater Yellow Lady's Slipper	No collections from the region in ARCTOS. Hulten has records near Haines and Skagway. E-flora BC has a record from Bennett Lake on the BC side of the border.
Cypripedium passerinum	Northern Lady's-slipper	Collected from near Haines in 1970 and again in 1979 (same location).
Goodyera oblongifolia	Rattlesnake Plantain	Evergreen orchid found in uplifted beach forests. The white central stripe and netting of the leaves is unmistakable. A few collections in ARCTOS, all from Sitka or north. Southeast Alaska appears to be where this species reaches its northern limits. It is reported found on Haida Gwaii, so could be presumed to occur in the southern part of the region.
Malaxis monophyllos	White Adder's-mouth	Collections in ARCTOS spanning the region (with some gaps).
Malaxis paludosa	Bog Adder's-mouth	Only a handful of collections from the region, from eastern Chichagof, also near Juneau, and from Wrangell Island. PacNW herbarium consortium has a couple of additional collections from northern Prince of Wales Island.

Neottia convallarioides	Broad-lipped Twayblade	A handful of collections in ARCTOS, from Chichagof Island, Admiralty Island, near the Stikine River Mouth and on the Cleveland Peninsula. Candidate for refugial species? (reported from Southeast Alaska, but nearest other locations are southern BC and the Aleutians)
Neottia cordata	Heart-leaved Twayblade	Small two-leaved perennial orchid common in moderately to highly productive forests Collections from throughout the region
Piperia unalascensis	Alaska Bog-orchid	For collections in ARCTOS from the region - two from Takhin Ridge outside of Haines, one from Glacier Bay, and one from Red Bluff Bay on Baranof Island.
Platanthera aquilonis	Northern Green Bog Orchid	Three collections from the far northern mainland, in the vicinity of Haines, Yakutat, and in the St. Elias Mountains.
Platanthera chorisiana	Choris' Bog-orchid	Infrequently found small orchid of bogs. The two oval basal leaves and spurred flowers distinguish it from other bog orchids. Collections spanning much of the region, but not upper Lynn Canal, nor Prince of Wales and associated outer islands.
Platanthera dilatata	White Bog-orchid	Slender white flowered orchid found in beach meadows and rich fens. Many collections in ARCTOS spanning the region.
Platanthera ephemerantha	White-lip Rein Orchid	A handful of collections of this species in ARCTOS, from Prince of Wales, Kuiu, Kruzof Islands, and Glacier Bay.
Platanthera huronensis	Green Bog-orchid	Collection records suggest this species is found primarily in the northern part of Southeast Alaska.
Platanthera hyperborea	Northern Bog-orchid	There are a handful of collection in ARCTOS from the far northern mainland identified as this species. This species was included in both the preliminary checklist (as var. hyperborea) and in Hall's 2010 treatment (where she says it also includes P. convallariifolia). FNA suggests this species only occurs in Greenland, but notes it has been confused with Northern Green Bog Orchid (Platanthera aquilonis), and e-Flora BC redirects this species to P. aquilonis, so that seems like the most likely option for which species Muller's treatment referred to. Hall's 2010 treatment may be better referring to Green Bog-orchid (Platanthera huronensis), however.
Platanthera obtusata	Small Bog-orchid	A small whitish green flowered orchid found in forested beach fringe in northern southeast Alaska. Three collections in ARCTOS, all from the northern mainland, with the southernmost near the Endicott River.
Platanthera orbiculata	Pad-leaved Bog-orchid	Large rare orchid with a single pair of broadly oval basal leaves found in productive forests Four collections in ARCTOS from the southern third of the region.
Platanthera stricta	Slender Bog-orchid	Common greenish flowered orchid of bog-forest transitions and fens. Many collections from across the region.
Spiranthes romanzoffiana	Hooded Ladies-tresses	Collections spanning the region from south to north, but only one from the outer islands in ARCTOS.

Agrostis stolonifera	Creeping Bentgrass	Introduced grass of wasteplaces Collections or reports (in AKEPIC) from across the region, primarily associated with towns and road systems. Relatively few reports from the northern mainland.
Alopecurus aequalis	Short-awn Foxtail	Scattered collections from across most of the region.
Alopecurus geniculatus	Water Foxtail	Introduced in Southeast Alaska. May not be established in the region, only a couple of collections, and no other reports in AKEPIC (where it is listed as introduced).
Alopecurus pratensis	Meadow Foxtail	Introduced to Southeast Alaska. Collections from the northern mainland, but many reports in AKEPIC from many communities across the region, and Prince of Wales Island road system.
Anthoxanthum hirtum	Northern Sweetgrass	Collections from across much of the region, though apparently none from the southern outer islands.
Anthoxanthum monticola	Alpine Sweetgrass	Most collections from northern mainland, also collections from the far southern mainland. Apparently no island collection records.

Arctagrostis latifolia	Polargrass	A few collections, one from Stikine River mouth, three from above Greens Creek (Admiralty Island), and one from Dyea.
Arctophila fulva	Pendant Grass	Only collections in PacNW herbaria are from Yakutat.
Arrhenatherum elatius	Tall oatgrass	Few collections or reports from the region. Most recent (2007) from Hoonah road system, but also older reports from Sandy Bay, Prince of Wales Island, Mitkof Island, and Sitka. May not be established in the region.
Avena fatua	Wild Oat	Most recent report of this species was a collection made in Hoonah (1979). Probably not established in the region.
Beckmannia syzigachne	American sloughgrass	A single collection from Haines airport is the only one from the region in PacNW herbaria database.
Bromus aleutensis	Aleutian Brome	A 1939 collection from Hyder is the only one identified as this species in ARCTOS and showing up from the region. PacNW herbaria has no records from the, though shows numerous collections from BC (where this species does not appear to be recognized by e-Flora BC) and northwest Washington.
Bromus carinatus	California brome	Annual or biennial grass native from British Columbia south to California, introduced to the Yukon and northern southeast Alaska Apparently no collection records from Southeast Alaska, there are many records of this species from coastal British Columbia right up to the border with Southeast Alaska. When Bromus carinatus is searched in PacNW herbaria database, records that come up are B. sitchensis var. marginatus - so apparently that taxonomy treats this species as a variety of Alaska Brome (Bromus sitchensis).
Bromus ciliatus	Fringed brome	Perennial tufted grass with open nodding panicles A single collection from Glacier Bay is the only record from the region in herbaria database. Map in Field Guide to Alaska Grasses shows a record from Sitka.
Bromus commutatus	Meadow Brome	Grass Manual map does not show any records for the area. The only report appears to be an isolated record from the vicinity of Skagway included on Hulten's map for this species. Presumably not established in the region.
Bromus hordeaceus	Soft Brome	An old collection from Juneau (1940), and the Field Guide to Alaska Grasses includes a report from Hyder. No records in AKEPIC database from the region. This species is probably not established in the region.
Bromus inermis	Smooth Brome	A few scattered records (collections and AKEPIC reports) from towns or road systems in the region, most from the northern mainland.
Bromus pacificus	Pacific Brome	Collection records from southwest Chichagof Island and south (but none from the mainland) Pacific Northwest coast endemic that apparently reaches the northern extent of its range in Southeast Alaska.
Bromus richardsonii	Richardson Brome	It's unclear whether this occurs in the area (Grass Manual maps suggests no), or whether it's better called B. ciliatus (USDA-PLANTS says yes, and Grass Manual map suggests it's closer to here than B. richardsonii). Hulten indicates a report from the Stikine River, but there are no collections in PacNW herbaria database.
Bromus secalinus	Rye brome	Weedy annual grass with stongly flattened, awned spikelets A single 2007 report in AKEPIC from Haines. Anderson also included this species in a 1918 report (referenced in AKEPIC). May not be established in the region.
Bromus sitchensis	Alaska Brome	A few scattered collection from across much of the region, except none from the northern gulf coast.
Bromus tectorum	Cheatgrass	Three reports - Haines (1921), Juneau (2010), and Prince of Wales Island (1997). May not be established in the region.

Calamagrostis nutkaensis	Pacific Reedgrass	Common rhizomatous grass of estuary meadows and of Sitka spruce dominated headlands. Suprisingly few collections mostly from the far southern portion of the region. Also from Port Snettisham and Lisianski Inlet.
Calamagrostis purpurascens	Purple reedgrass	Perennial tufted grass with a spike-like panicle A single collection from Takhin Ridge outside of Haines is the only record from the region.
Calamagrostis stricta	Northern Reedgrass	A few scattered collections from northern half of the region. (Somewhat difficult to be sure due to taxonomic changes and/or subspecies not always showing up under species search.)
Cinna latifolia	Woodreed	Scattered collections, mostly from the northern mainland.
Dactylis glomerata	Orchard Grass	A few collections, but many reports in AKEPIC from across the region.
Danthonia intermedia	Timber Oatgrass	Collected on Mt. Bokan, Prince of Wale Island. Also reported from Juneau area and east side of Lynn Canal.
Danthonia spicata	Poverty Oatgrass	Collected on southern Prince of Wales Island.
Deschampsia cespitosa	Tufted Hairgrass	Many collections from across the region.
Deschampsia danthonioides	Annual hairgrass	Grass manual suggests it does not occur in Southeast Alaska. Hulten included dots at Juneau and near Yakutat, but apparently no other reports.
Deschampsia elongata	Slender Hairgrass	Grass manual does not indicate presence of this species in Southeast Alaska. Few collections, but many reports of this species in AKEPIC from Prince of Wales Island, eastern Chichagof Island, and near Petersburg.
Deschampsia flexuosa	Wavy Hairgrass	Grass manual map does not indicate records from Alaska. Hulten included a report from Sitka, which appears to be the only one from the region.
Elymus alaskanus	Alaskan Wheatgrass	The Field Guide to Alaska Grasses does not show this species occurring in Southeast Alaska. Most records in ARCTOS of this species are of ssp. latiglumis which e-Flora BC indicates is synonymous with Arctic Wheatgrass (Elymus violaceus), which the field guide treats as a valid species.
Elymus glaucus	Western Ryegrass	Scattered collections, mostly from the northern half of the region.
Elymus hirsutus	Northern Ryegrass	Scattered collections from across the region, mostly on the outer islands or outer coast.
Elymus repens	Quackgrass	Introduced A few collections, and many reports in AKEPIC from the northern half of the region.
Elymus sibiricus	Siberian wildrye	Introduced Apparently no collections from the region. Reports in AKEPIC from Juneau, Skagway, Haines, and Haines Highway.
Elymus trachycaulus	Slender Wheatgrass	Scattered collections from across the region, though more on the northern mainland.
Elymus violaceus	Arctic Wheatgrass	A few collections from the northern mainland.
Elymus x yukonensis	Yukon Wheatgrass	Current taxonomy is a little unclear, but there do not appear to be any records of this species from the region. Inclusion in preliminary checklist appears to be based on Hulten's map. The circle around reported locations includes the far northeastern part of the region (without any reports from the Alaska side of the border).
Festuca altaica	Rough fescue	Perennial tufted grass with open panicles and purplish-bronze spikelets found in open areas of upper elevations Collections near the border outside of Haines and Skagway, also from the Alsek River near the border.
Festuca brachyphylla	Alpine Fescue	Collections from across the region, but primarily from the mainland (especially the northern mainland).

Hordeum brachyantherum	Meadow Barley	Scattered collections from across the region.
Hordeum jubatum	Foxtail Barley	A few collections, most from the northern part of the region. This species is included in AKEPIC database, and may be introduced to the region. (It is thought to be native to at least part of the state, but has been spread beyond its native range by human activity.)
Hordeum vulgare	Barley	Though probably cultivated in historic times, it seems unlikely that this species has naturalized in the area. No collections from the region. A single (1918) report in AKEPIC from Juneau.
Leymus mollis	Dune Grass	Robust bluish grass often forming extensive colonies just above the high tide line Collections spanning the region, though apparently none from the southern outside islands.
Lolium multiflorum	Italian Ryegrass	A handful of collections from the region. AKEPIC database includes reports from several communities or sites of human disturbance, including Ketchikan, Wrangell, Petersburg, Sitka, Kake, and Juneau.
Lolium perenne	Perennial Ryegrass	A handful of collections along with many records in AKEPIC database from Gustavus and Juneau south.
Melica subulata	Alaska oniongrass	A handful of collections scattered along islands of the outer coast from as far north as Kruzof Island (which appears to be the northernmost record of this species - though it has also been reported from Unalaska).
Phalaris arundinacea	Reed Canarygrass	A few scattered collections from across the region. Many reports in AKEPIC from almost anywhere with roads or settlements.
Phalaris canariensis	Annual Canarygrass	A 1926 collection from Juneau in ARCTOS and a 2004 AKEPIC report from the Wrangell Ranger district are the only reports of this species from the region.

Poa alpina	Alpine Bluegrass	Tufted grass with wide basal leaves and fat spikelets found at high elevations and colder microsites. Collections from across much of the region, though none from the southern half (or more) of the mainland.
Poa annua	Annual Bluegrass	A few collections from across the region. Many reports in AKEPIC database from human impacted areas.
Poa arctica	Arctic Bluegrass	Collections primarily from the northern mainland and northern-most islands. Also collected near Hyder and on Revillagigedo Island.

Poa eminens	Large-flower Speargrass	Rhizomatous grass of beaches, tide flats and brackish meadows. The large compact inflorescence is distinctive. Collections from the northern two thirds of the region. Apparently this species reaches the southern and eastern edge of its normal range in the region (it is considered a very rare species in BC, with a small number of records).
Poa glauca	Glaucous Bluegrass	Collections from the Stikine River and between Haines/Skagway and the BC border.
Poa interior	Inland Bluegrass	Collections in ARCTOS from near Yakutat and on Chichagof Island. Field Guide to grasses indicates additional records from near Sitka and Juneau.

Poa macrantha	Seashore Bluegrass	Collected from Sea Lion Cove on Kruzof Island, and near Yakutat.
Poa macrocalyx	Large-glume Bluegrass	Has been reported from as far south as Khaz Peninsula on West Chichagof. This appears to be the southern-most reported occurrence in the eastern portion of the range.
Poa nemoralis	Wood Bluegrass	A single 1959 collection from the vicinity of Haines is the only one in ARCTOS of this species. See also Inland Bluegrass (Poa interior).
Poa palustris	Fowl Bluegrass	Collections from across the region.
Poa paucispicula	Alaska Bluegrass	Collections primarily from the northern part of the region, with one from northern Prince of Wales being the only collection south of Sitka in the region.(Also occurs on Haida Gwaii and Vancouver Island, so perhaps should be expected throughout the region.)
Poa pratensis	Kentucky Bluegrass	Collections from the northern half of the region, reports in AKEPIC from across the region in human impacted locations. (Native susbspecies primarily found in the north?)
Poa secunda	Pine Bluegrass	No collections from the region. Appears to be more continental (present on the interior side of the coast mountains in BC).
Poa stenantha	Northern Bluegrass	Collections in ARCTOS from across most of the region, but more from the northern half.
Poa trivialis	Rough Bluegrass	Few collections from the region. Reports in AKEPIC mostly from central and southern islands along road systems.
Podagrostis aequivalvis	Northern Bentgrass	Quite a few collections from across the region other than the Northern Gulf Coast. (Present further west, so should be expected?)
Podagrostis humilis	Alpine Bentgrass	Grass of wet meadows mostly in the alpine. A few scattered collections in ARCTOS from the region.
Polypogon monspeliensis	Rabbitfoot Grass	A single 1946 collection from Juneau is the only record from the region. Probably not established in the region.
Pseudoroegneria spicata	Bluebunch Wheatgrass	A single 1961 collection in ARCTOS from Ketchikan is the only report of this species from the region. Given overall distribution of this species, it may be worth revisiting this collection to verify ID.
Puccinellia distans	Weeping Alkaligrass	No collections from the region, though e-Flora BC includes one from White Pass just north of the border.
Puccinellia nutkaensis	Pacific Alkaligrass	Collections in ARCTOS from the length of the region, but only collected from the outer coast near Yakutat.
Puccinellia nuttalliana	Nuttall's Alkaligrass	Although included in the preliminary checklist and Hall's 2010 treatment, there appear to be no collections recorded from the region. E-flora BC includes a few well to interior side of the coast mountains.
Puccinellia phryganodes	Creeping Alkaligrass	No collections in ARCTOS from the region (one initially identified as this species was re-labled Puccinellia sp - specifically rejecting this one). Nearest collection appears to be from vicinity of Bering Glacier.
Puccinellia pumila	Dwarf Alkaligrass	Only a few collections from the region, but overall distribution suggests it could be expected throughout in appropriate habitat.
Schedonorus arundinaceus	Tall Fescue	A few collections from the northern part of the region in ARCTOS. Reports in AKEPIC from across much of the region, but not Lynn Canal, and few from Prince of Wales Island.
Schedonorus pratensis	Meadow Fescue	No collections in ARCTOS currently labeled as this species. Several reports in AKEPIC from NE Chichagof in logged area. (A collection from that area originally identified as this species is currently labeled Schedonorus arundinaceus.) Field Guide to Alaska Grasses indicates a record from Hyder as well.
Schizachne purpurascens	False Melic	No collections from the region. Nearest records are from the Canadian side of the coast range. Also known from South Central Alaska.
Torreyochloa pallida	Pale False Mannagrass	Collections in ARCTOS from across the region.

Trisetum spicatum	Downy Oatgrass	Collections from across the region.
Triticum aestivum	Bread wheat	A couple of collections in ARCTOS and a handful or reports in AKEPIC database. Unclear whether this species is established, or (seemingly more likely) if records are of non sustaining introductions.
Vahlodea atropurpurea	Mountain Hairgrass	Collections from throughout the region.

Potamogeton gramineus	Variable Pondweed	Scattered collections in ARCTOS spanning the region, but wide gaps (including none from northern outer islands).
Potamogeton natans	Floating Pondweed	Only two collections from the region in ARCTOS, one at Sitka the other on Revillagigedo Island.
Potamogeton perfoliatus	Clasping-leaf Pondweed	FNA indicates this species is not known to occur in Alaska (though Richardson's Pondweed (Potamogeton richardsonii) is said to be very similar, and has been considered a subspecies). The only collection from the region in ARCTOS has a note "=P. richardsonii", so it seems likely this species does not occur in the region unless P. richardsonii is included.
Potamogeton praelongus	White-stem Pondweed	Two collection locations have records in ARCTOS, Lake Eva on NE Baranof Island, and Bear Paw lake on E Chichagof Island.
Potamogeton pusillus	Small Pondweed	A single collection from Farm Island (Stikine River) is the only georeferenced collection of this species from the region in ARCTOS.

Stuckenia vaginata	Sheathed Pondweed	Hulten indicates a record in the vicinity of the Malaspina Glacier, though details are insufficient to tell whether it came from the Alaska side of the border. Apparently no other records from the region.
Zannichellia palustris	Horned Pondweed	Collections west of the region starting in the vicinity of the Bering Glacier, but apparently none from Southeast Alaska. Hall 2010 describes this species as common but often overlooked.

Ruppiaceae (Ditchgrass: 2 species)
