ANDERSON in 1867 published S. arguita* S. pallescens hiriis- 
guama, based on a specimen collected by BourGEAU at Lake Win- 
nipeg and having short aments on short peduncles, scales densely 
white pilose except at tips, and narrow, sharply serrate leaves. 
Throughout its range S. serissima has short aments and pilose 
scales, but not narrow and sharply serrate leaves. The three 
Manitoba specimens cited do have such leaves, and it is quite 
possible that they represent this form. ‘The leaves are not quite 
fully developed, and it seems hardly desirable to designate them 
as belonging to it without more and older material. On no. 70264 
the under surfaces of the leaves show scarcely any traces of glauces- 
cence. The leaves of all three are discolored in drying, however, 
which tends to obscure this character. 
On flowering specimens from Manitoba (Macoun and Herriot 
70262) and Alberta (Sanson 304, 309, 2167), a peculiar appearance 
has been observed. The capsules, nearly or quite full sized, but 
not mature, are minutely roughened or papillate, and the surface, 
viewed by reflected light, has a striking and deceptive resemblance 
to a fine lustrous puberulence.
