|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.
|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.
|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.|
|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 (does it occur along shorelines of 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.|
|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.|
|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.|
|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.|
|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.|
|Scientific Name||Common Name||Summary|
|Aconitum delphiniifolium||Monkshood||Uncommon perennial herb most often found in subalpine meadows, but also along creeksides, and rarely forest openings. Deeply lobed palmate leaves and showy helmet-shaped blue to purple flowers make this poisonous plant quite distinctive.
Collections from cross the region in ARCTOS, though records appear to be lacking from the central mainland and inner islands (it's possible there are addition non-georeferenced records fromm those areas).|

|Anemone richardsonii||Yellow Anemone||Yellow-flowered plant of meadows and mountains.
Collections in ARCTOS from the northern inside mainland and northeast Chichagof 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).|

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.)|

|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.|
|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 .|
|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.

|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.|

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 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

|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 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.|

|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.|

|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.|

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.|

|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.|

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.|

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.|
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).|

|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.|

|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 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.|
