summit of the neiglibouring ^Eount Verstovla, in the year 1827." As Co- 

 villesays, it "is a characteristic plant of the Sitkan floral district extenjhig 

 from the southernmost limit of Alaska northward and westward along the 

 coast to Cook Inlet and the eastern end of Kadiak Island.'* South of Sitka 

 it is a ''very common plant at the coast" J. K. (Henry) of British Columbia, 

 from where I have also seen specimens from the Yale and Kootenay Districts. 

 In the United States it has been found in western Washington and western 

 Oregon, but also in southeastern Oregon (Bhie Mountains) and eastern 

 Washington (Wallowa and Steins Mts.), in Idalio (Elk River, Clear County), 

 and Montana (Belton, Flathead County). The species is readily distin- 

 guished by the satiny pubsscence of the lower surface of its mostly more or 

 less obovate leaves. Sometimes specimens of a pubescent form of S. Scoul- 

 eriana with ^vhich I shall deal in a later article, have been taken for *S. sit- 

 chenshy but the villose pubescence of these forms is very different as also 

 usually is the shape (more ellijitic) of their leaves. 



Andersson (1867) ^jroposed two varieties of S. sitcherhsis: '^ — comjc^fa; 

 foliis angustioribus; amentis ob capsulas crassissimas et breves subscssiles 

 valde dcnsifloris," and '' — - denudata; foliis subtus demum glabratis tenui- 

 bus." The types of both were collected by Lyall along the lower Frazer 

 River. There is before me a specimen of LyalFs from this region collected 

 in 18.59 (in., f. ; N.). The sheet on wliich it is mounted bears a label '' Salix 

 sitchensis Bong, congcsia Ands." in Andersson's own handwriting. On the 

 label is \\Titten by another hand '* Lower Fraser River, C. B. Wood, 1839," 

 and it is referred to a piece with rather old female amcnts. I do not know 

 of a collector C. B. Wood. All the pieces, In my opinion, represent typical 

 S. sitchensis, Anotlier specimen of LyalFs, lower Frazer River, Sumass, 

 swamps, April 20, 18o7, does not agree with either variety. Whether var. 

 denudata really belongs to S. sitchensis remains doubtful, especially as An- 

 dersson (in 1808) states that the leaves of it are **iis S. silesiacae v. S. 

 cinercae hand absimilibus." There are specimens collected by Coville & 

 Kearney (Xo. 44-2) and B. E. Fernow, on June 5, 1899, at Fort Wrangell, 

 southeastern Alaska, which Coville regards (Herb. W.) as *^ probably a 

 denudate " S. sitchensis. Fernow's plant in Herb. Cor. is mixed with S. 

 Barclayij and without mature leaves, flowers or fruits it is impossible to 

 decide whether it is a hybrid or a variety of S. sitchensis. Andersson's third 

 var. ajanensis (18G8), which he (18(57) first published as a quasi subspecies 

 as 5. sitchensis *5. ajanensis, came from northeastern Asia, and is unknown 

 to me.
