Scientific NameCommon NameSummary
Populus balsamiferaBalsam PoplarUnclear 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 tremuloidesQuaking AspenJust two collections mapped from the region in ARCTOS,one from outside of Haines and the other outside of Skagway.
Populus trichocarpaBlack CottonwoodCollections in ARCTOS from the across all but the far southern mainland. Also from Chichagof and Baranof Islands.
Salix alaxensisFeltleaf WillowUnderside of leaves with a dense white or creamy felt Collections in ARCTOS from the mainland and islands near the Stikine River mouth.
Salix arbusculoidesLittletree WillowMid sized shrub or tree with narrowly elliptic leaves and leaf-like stipules Reported to occur in the region, there are no georeferenced collections of this species in ARCTOS or on the eFlora BC map.
Salix arcticaArctic WillowDwarf shrub with erect or trailing branches Collections in ARCTOS from across the region.
Salix barclayiBarclay's WillowShrubs to 6ft tall, leaf out and flowering co-occur Collections in ARCTOS primarily from the mainland and smaller islands of the Stikine River delta. Also a collection from Chichagof Island.
Salix barrattianaBarratt's WillowUpright shrub to 2ft with often vertical leaves grey with long hairs No collections in ARCTOS mapped from the region, though Hulten includes a dot on the map near Skagway. Overall distribution of collections suggests this species is more continental, and if it occurs at all, it is probably only at the margins.
Salix bebbianaBebb WillowLarge 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 commutataUndergreen WillowDensely 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 fuscescensAlaska Bog WillowLow 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 glaucaGrayleaf WillowHighly 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 hookerianaCoastal WillowShort 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 interiorNarrow-leaf WillowMid 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 lasiandraPacific WillowSome 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 myrtillifoliaLow Blueberry WillowLow spreading shrub to 2ft, plants spreading by layering Two collections mapped in ARCTOS from near the border outside of Skagway.
Salix niphocladaBarrenground WillowLow 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 planifoliaDiamondleaf WillowLow to tall shrubs with precocious catkins Collections in ARCTOS mapped from Haines and Skagway to the northern border of the region.
Salix polarisPolar WillowDwarf shrub of moist late snowfields and scree slopes Single collections mapped in ARCTOS from southern mainland and Coronation island with additional collections from the northern mainland in mountains around Lynn Canal.
Salix prolixaMackenzie's WillowMedium 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 pseudomonticolaFalse Mountain WillowNo collections in ARCTOS from the region, though Hulten includes a dot on the border northeast of Juneau (Taku River?).
Salix pulchraTea-leaved WillowLow 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 reticulataNetleaf WillowDwarf 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 richardsoniiRichardson's WillowLow 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 rotundifoliaLeast WillowDwarf 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 scoulerianaScouler's WillowTall 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 setchellianaSetchell's WillowDwarf shrub endemic to Alaska, the Yukon and extreme northwestern British Columbia Several collections in ARCTOS from the Yakutat forelands.
Salix sitchensisSitka WillowMid sized shrub to tree with subprecious to coetaneous catkins. Leaves have distinctive silky hairs on undersurface Collections in ARCTOS from across the region, though relatively few on the southern outer islands.
Salix stoloniferaCreeping WillowDwarf shrub with above or below ground trailing branches Collections mapped in ARCTOS from across the region, though apparently none from northern outer islands.
