Hab. From Hudson's Bay to the Prairies of the Rocky Mountains, and to Fort Franklin on the Saskat- 

 chawan. Dr Richardson. Drummond. Boiiglas. Head waters of the Coluaibia. Douglas. — Copious 

 specimens of this plant show that it is. like other Willows, subject to much variation, and the appearance of 

 the young and old foliage, and young and old female catkins, are very different. The colour of the bark is 

 sometimes pale-yellow or deep-brown, sometimes almost black. The lax female catkins, the long, narrow, 

 silky germens, and above ail the great length of the stipes, are its best distinguishing features. Dr Barratt 

 finds the same species about Middletown, Pennsylvania, and it is probably not uncommon in the United States, 

 It is the largest of the " Cinere^" group, being sometimes ten feet high.

(The species of this group constitute large spreading shrubs and small trees, and are the first to put forth 

 their catkins in the spring.)

Hab. Lake Winipeg and Saskatchawan. Dr Richardson. Douglas, Newfoundland. Miss Brenton,— 

 ^. Norway House Fort. Dr JJ^c^arcf son.— Branches with female catkins and young foliage, from the Saskat- 

 chawan, are marked as truly S. discolor o^ WillJenow, by Dr Barratt_; and one or two specimens with older 

 foliage, gathered at another period, and in another part of the country, are supposed to be the old fohago. The 

 Newfoundland specimens exactly accord with United States specimens sent me by Dr Barratt. Our var. ^. 

 has, besides the characters above alluded to, a less silky germen, and it may perhaps constitute anew species.

Hab. Fort Franklin on the Mackenzie River. Dr Richardson.—Thii appears to be a very distinct 

 species, remarkable for the great length o.f the style. It is to be regretted that very few specimens were 



procured of it.
