Hab. North -West coast of America. A, MenzieSy Esq,— The only specimens 1 have ever seen of this 

 plant are from my valued friend Mr. Menzies. In habit it quite agrees with the preceding species, but it is 

 entirely destitute of the white tomentum on the unilerilde of the leaves and older brauches, which are 

 wholly glabrous : the latter are glossy, deep purplish-browu.

 rocky banks of the Spokau, Flathead, Salmon, and M*Gillivray Rivers, in tlie interior. Mr. Menzies^ DouylaSy 

 Dr. Scouler. — The leaves are more or less hairy, and more or less pale, but never so white as to be " niveo- 

 tomentosa" or to justify the name of " discolor" being given to the plant, as fiir as our specimens are ronremetl ; 

 but in the S. discolor of Dr. Torrey, according to a sample in my Herbarium, the leaves are snowy white 

 wiih hail's on the underside.

Hab. Moist woods, near the source of the Columbia, Dnuimand, Mouth of the Columbia, and at 

 Puget Sound. Dovglas, Dr. Scouler.— Mr, Dougbts is disposed to consider this plant distinct from the S, 

 Aruncus of the United States and of Europe; but I confess I can see no difference.
