HOOKER’S WILLOW. 
SALIX Hookekiana. (Barratt, MSS); ramis valde robustis 
pubescenlibus, junioribus dense tomentoso-lanatis, foliis 
late obovatis fere sabrotundatis rigidiusculis serratis mar- 
gine plants supra [adultis) nudiusculis subtus tomentoso- 
lanatis, stipulis [ semicordatis'] , amentis cylindraceis cras- 
sis, squamis longe densissime lanatis, ovariis longe stipi- 
tatis lanceolatis glaberrimis, stylo breviusculo, stigmatis 
lobis integris. Hook. Flor. Bor. Am., vol. 2. p. 145. t. 180. 
This small tree, nearly allied to S. cinerea , we found 
of common occurrence in the lower part of the territory 
of Oregon towards the sea, particularly frequent on the 
margins of ponds and in wet places near the outlet of 
the Wahlamet, where it attained the height of eight or 
ten feet. It was also found in the territory of Hudson’s 
Bay, near the Grand Rapids of the Saskatchewan, by 
Douglas. The leaves are remarkably protean in their 
form, sometimes wholly soft and villous on both sides, 
more commonly so beneath, the nature of the pubes- 
cence also varying till it at times resembles in appear- 
ance and to the touch the most brilliant velvet; the old 
leaves are generally obovate, smooth and shining above, 
often nearly so beneath, and then of a bluish-green or 
glaucous hue; they are, moreover, both acute and ob- 
tuse, sometimes even rounded at the extremity, and are 
generally among the largest, or at least widest, of Wil- 
low leaves. The stipules on some branches are very 
conspicuous, circular and serrated. The male aments are 
extremely pilose in an early stage, as in our S. conifera, 
to which this species makes some approach; the stamens 
are two to each scale. The capsule is ovate-lanceolate
