Salicaceae
From Natural History of Southeast Alaska
Family: Salicaceae
Group: Vascular Plant, Species
Scientific Name | Common Name | Summary |
---|---|---|
Populus balsamifera | Balsam Poplar | Unclear whether this species occurs in Southeast Alaska. ARCTOS herbarium records are all of Populus balsamifera ssp. trichocarpa (Populus trichocarpa) and it seems plausible that this species is restricted to interior regions of BC into Yukon and Alaska - not reaching the coast before South Central Alaska. |
Populus tremuloides | Quaking Aspen | Just two collections mapped from the region in ARCTOS,one from outside of Haines and the other outside of Skagway. |
Populus trichocarpa | Black Cottonwood | Collections in ARCTOS from the across all but the far southern mainland. Also from Chichagof and Baranof Islands. |
Salix alaxensis | Feltleaf Willow | Underside of leaves with a dense white or creamy felt Collections in ARCTOS from the mainland and islands near the Stikine River mouth. |
Salix arbusculoides | Littletree Willow | Mid sized shrub or tree with narrowly elliptic leaves and leaf-like stipules Reported to occur in the region, there are no georeferenced collections of this species in ARCTOS or on the eFlora BC map. |
Salix arctica | Arctic Willow | Dwarf shrub with erect or trailing branches Collections in ARCTOS from across the region. |
Salix barclayi | Barclay's Willow | Shrubs to 6ft tall, leaf out and flowering co-occur Collections in ARCTOS primarily from the mainland and smaller islands of the Stikine River delta. Also a collection from Chichagof Island. |
Salix barrattiana | Barratt's Willow | Upright shrub to 2ft with often vertical leaves grey with long hairs No collections in ARCTOS mapped from the region, though Hulten includes a dot on the map near Skagway. Overall distribution of collections suggests this species is more continental, and if it occurs at all, it is probably only at the margins. |
Salix bebbiana | Bebb Willow | Large shrub or small tree frequently with diamond pattern on the trunks. A single collection from the Stikine delta mapped in ARCTOS from the region. |
Salix commutata | Undergreen Willow | Densely branching shrub between 3-6ft tall Collections in ARCTOS from the Glacier Bay north and west on the mainland. One collection from the BC side of the border near Hyder. |
Salix fuscescens | Alaska Bog Willow | Low shrub with trailing stems No collections within the region mapped in ARCTOS. Nor any particularly close. Reported in the Preliminary Checklist and Hall's 2010 treatment as being found on Chichagof Island, Hulten does not show this species occurring in the region. It is unclear on what basis this species was included on prior lists. |
Salix glauca | Grayleaf Willow | Highly variable short to tall shrub Collections in ARCTOS from Yakutat Forelands and St. Elias mountains, also from near the border outside of Skagway. Many collections on the Canadian side near the border from the Taku River north. |
Salix hookeriana | Coastal Willow | Short to mid sized shrub Collections in ARCTOS from the Yakutat Forelands are the only ones from the region. (This species is also found on Haida Gwaii.) |
Salix interior | Narrow-leaf Willow | Mid sized shrubs to trees found on sand bars. Spreads clonally by root shoots. Three collections in ARCTOS from the Stikine River and delta, each identified as S. interior on the sheet, but listed as S. exigua ssp interior in ARCTOS taxonomy. |
Salix lasiandra | Pacific Willow | Some disagreement in taxonomy - the FNA account for S. lucida recognizes S. lasiandra as a separate species, though ARCTOS and e-Flora BC treat it as within S. lucida. Collections mapped in ARCTOS from mainland near Hyder, Stikin River, and northern Lynn Canal. |
Salix myrtillifolia | Low Blueberry Willow | Low spreading shrub to 2ft, plants spreading by layering Two collections mapped in ARCTOS from near the border outside of Skagway. |
Salix niphoclada | Barrenground Willow | Low to mid sized shrub No collections in ARCTOS mapped from the region. Distribution of records shown on e-Flora BC map suggests this species does not occur on the ocean side of the Coast Range in this region. |
Salix planifolia | Diamondleaf Willow | Low to tall shrubs with precocious catkins Collections in ARCTOS mapped from Haines and Skagway to the northern border of the region. |
Salix polaris | Polar Willow | Dwarf shrub of moist late snowfields and scree slopes Single collections mapped in ARCTOS from southern mainland and Coronation island with additional collections from the northern mainland in mountains around Lynn Canal. |
Salix prolixa | Mackenzie's Willow | Medium to tall shrubs A single mapped collection in ARCTOS from Sergief Island near the Stikine River mouth. This collection seems to be an outlier from the overall distribution of this species (more southern overall, but more interior in the north) |
Salix pseudomonticola | False Mountain Willow | No collections in ARCTOS from the region, though Hulten includes a dot on the border northeast of Juneau (Taku River?). |
Salix pulchra | Tea-leaved Willow | Low to tall shrubs with linear leaf-like stipules and precocious flowering No mapped collections of this species from the region in ARCTOS. Closely related to Diamondleaf Willow (Salix planifolia) - see FNA notes on that species for more about where this one may be expected to occur. |
Salix reticulata | Netleaf Willow | Dwarf shrub with distinct reticulate leaves
Collections from ARCTOS across much of the region. Gaps may be due to lack of effort in preferred mountain habitats. Possible refugial species (cf. Haida Gwaii population and southern outer islands)? |
Salix richardsonii | Richardson's Willow | Low to tall shrubs with precocious catkins A single collection mapped in ARCTOS from the margins of the region on the Malaspina Forelands. Overall distribution of this species seems to be more northerly and continental. |
Salix rotundifolia | Least Willow | Dwarf shrub with erect stems No mapped collections in ARCTOS from the region. Nearest records shown are from southwest Yukon Territory. Not treated in e-Flora BC, though Hulten's map includes a dot near White Pass. |
Salix scouleriana | Scouler's Willow | Tall shrubs or trees Scattered collections in ARCTOS from across the region. Distribution of collections seems to suggest this species could occur throughout the region, though there wide areas where it has not been collected. |
Salix setchelliana | Setchell's Willow | Dwarf shrub endemic to Alaska, the Yukon and extreme northwestern British Columbia Several collections in ARCTOS from the Yakutat forelands. |
Salix sitchensis | Sitka Willow | Mid sized shrub to tree with subprecious to coetaneous catkins. Leaves have distinctive silky hairs on undersurface Collections in ARCTOS from across the region, though relatively few on the southern outer islands. |
Salix stolonifera | Creeping Willow | Dwarf shrub with above or below ground trailing branches Collections mapped in ARCTOS from across the region, though apparently none from northern outer islands. |
