was to be expected from what is known of the two most nearly allied species. 
S. hookeriana was first described as having ‘very smooth’ capsules, but subsequent 
observations have shown that they are more frequently tomentose, and a like varia- 
tion, though in less degree, prevails in the case of S. richardsonii ; but in neither is 
this variation so pronounced as to lessen the surprise with which we find the one 
species of the group heretofore most conspicuous for its silky vesture appearing, as 
in Mr. Tweedy’s specimens, so markedly glabrate. The leaves, and in fact the aments 
as well, bear a very close and deceptive resemblance to some forms of 8. barclayi; but 
the aments are closely sessile, terminal as well as lateral, the styles longer and the 
stigmas bifid; the leaves alone could scarcely be distinguished one from the other.”’ 
The type specimens have been deposited in the United States National, the Gray, 
and the Kew herbariums.

‘Alpine form. This might with propriety, from the description alone, be referred 
to 8. glauca alpina Anders, DC. Prodr. xvi, pt. 2, 281, but the author cites S. glauca 
macrocarpa Ledeb., as a synonym and apparently with the illustration given in 
Ledebour’s Flora Rossica, fig. ¢, tab. 468, Our plant has little in common as a special-
