 on the Mackenzie River. Dr Richardson. — Leaves from two to four or nearly five inches long-. Mature 

 female catkins very large, I regret not to have perfect specimens of this plant. Indeed I should not have 

 ventured to introduce it, were it not that Dp Barratt considers it to be the same as S. villosa of D. Don, in

Hab. North West America, on the Columbia. Dr Scolder, Fort Vancouver. Tolmie.—^Ark dark- 

 brown, almost black in the older specimens. Young leaves silky on both sides : adult ones (rarely exceeding 

 an inch in length) nearly glabrous above, beautifully silky beneath. Catkins an inch and a half long, droop- 

 ing : the silky germens are much concealed by the large dark-coloured scales.

Hab. Near the Grand Rapids of the Saskatchawan, rare. Douglas. N. W. Coast of America. Scouler. 

 — A stout but low growing shrub, with very thick straight branches. The male catkins look like a dense 

 cylindrical mass of wool, which entirely conceals the scales, the stamens only being protruded beyond the 

 wool. The leaves are 2-3 inches long, one inch to an inch and a half wide, clothed with greyish woolly 

 down beneath. Pistils perfectly glabrous, even its stipes ; and the lobes of the stigma are always entire.

Hab. Kotzebue's Sound. Beechey, Fort Norman and Fort Franklin on the Mackenzie River. Dr

 handsome Salix, which were all Dr Arnott and myself were acquainted with from Kotzebue's Sound, we 

 have fully described in the Flora above quoted. In the present collection are fine flowering and fruiting
