longer-peduncled and more slender aments, the longer yellowish scales, 
the more slender and pointed capsules and the entire stigmas. From 
S. phylicifolia distinguished by the pubescence of the much longer 
leaves, the shorter capsules, and the entire stigmas.

Tall shrub or small tree, up to 4 m. high; branchlets thick, densely 
canescent-tomentose, with persistent tomentum: leaves ovate, broadly 
elliptic or obovate, very cinereous-tomentose beneath with persistent 
tomentum: aments similar to those of the typical form of the species.—

In typical S. rostrata Richardson (S. Bebbiana Sargent) the new 
branchlets are pubescent at tip, but the pubescence is early deciduous; 
and the leaves, varying from ovate-oblong to oblanceolate, lose much 
of their pubescence in age, becoming glabrate or only sparsely pubes- 
cent but obviously veiny beneath. In the common Rocky Mountain 
representative of the species, S. rostrata, var. perrostrata, n. comb.,= 
S. perrostrata Rydberg, Bull. N. Y. Bot. Gard. ii. 163 (1901), the leaves 
are less rugose or almost plane and glabrate in age, and the branchlets 
glabrous or quickly glabrate. And in the largest extreme of the spe- 
cies, var. luxurians Fernald, Ruopora, ix. 223 (1907), with the large 
capsules (9-12 mm. long) on pedicels 5-8.5 mm. long, the branchlets 
are as pubescent as in var. capreifolia, but the very large leaves are 
sparingly pubescent or glabrescent and as little rugose as in var. per- 
rostrata. The var. capreifolia presents the most extreme develop- 
ment of pubescence in the species and may prove to be the same as 
S. vagans, 1. S. rostrata, forma latifolia Anderss., Mon. Sal. 88 (1865) 
described from Vancouver Island, while var. perrostrata shows the 
opposite tendency. In its foliage var. capreifolia so closely simulates
