 reflesed stipules, readily distinguish this species, I am not acquainted with the male catkins.

Hab. Moist woods and prairies of the Saskatchawan. Dntmmond.—^. Lake Winipeg and the Saskat- 

 chawan. Br mchardson.—y. Great Slave Lake and the Mackenzie River. Dr Richardson.— ^o variable 

 are the leaves of this plant in point of size, shape, and texture, that all kinds may be seen between lanceolate 

 and almost exactly cordate. It is only fair to observe, that Dr Barratt is disposed to consider the ^. and y. 

 good species ; but I really do not possess sufficient materials to give satisfactory characters. The branches 

 vary from bright yellow to deep brown.-Another state probably of this plant is found by Mr Douglas oa 

 the Columbia River with quite entire leaves.
