Lysichiton camtschatcense (l.) Schott. Western Skunk 
Cabbage. 
About bogs and stream margins in the forest this plant occurs 
abundantly. In many localities it attains a large size, the leaves 
measuring 3 to 5 feet in length. (No. 35.) 
Veratrum viride Ait. Green Hellebore. 
Oceuwrs in the same situations as the skunk cabbage, but much 
less generally distributed. (No. 59.) 
Iris setosa Pall. Iris. 
One of the littoral plants, usually found associated with 
rye-erass, yarrow, ete., on gravelly deposits near the mouths of 
streams. (No. 21.) 
Salix, spp. 
At least three species of willow occur in the region. An 
arborescent form was found growing along the margins of large 
streams in company with Populus at Cordova Bay, Port Nell 
Juan, Hinchinbrook, and Montague islands. A shrubby species 
a few feet in height grew in masses about the margins of swamps 
and stream deltas at Cordova Bay and Port Nell Juan. A third 
form, a foot to eighteen inches in height, occurred on the mar- 
coins of ponds at Port Nell Juan associated with Myrica gale. 
Populus trichocarpa T. & G. Black Cottonwood. 
Poplars were found growing at the mouths of large streams 
and fringing forests at Cordova Bay, Port Nell Juan, and Valdez 
Inlet. About Valdez Inlet this tree oceurs also on side-hills with 
alders and seattered spruce. (No. 58; determined by Professor 
H. M. Hall.) 
Myrica gale Li. Sweet Gale. 
One of the most characteristic tundra shrubs. It occurs 
throughout the whole region, usually forming thickets about the 
edges of ponds and as a seattered growth in the tundra generally. 
(Nos. 8, 48.) 
Alnus sitchensis (Regel) Sargent. (A. alnobetula var. B. 
fruticosa (Rupr.) Winkl.) Shrubby Alder. 
One of the most abundant tree-like growths. It occurs along 
all stream courses, usually throughout their whole length. It 
is the first tree to take possession of the deforested areas on hill- 
sides. About timber-line heavy thickets of alder form a char-
