Had. Woody country, from the Saskatchavvan to the extreme Arctic regions, and from Labrador to the 

 more elevated of the Rocky Mountains. Unalaschka, Chamiss'o. Kotzebue's Sound. Lay and Collie. — In 

 size and foliage, few plants are more variable than this; yet none of our specimens have leaves so broad 

 or so obtuse as those of A. moniana ^vhich I possess from the south of Europe, of which, neverthe- 

 less, Mr. Brown, justly I think, esteems it a variety. Some of the specimens from the woody country are 

 tv\o and two and a half feet high, very leafy: while the more alpine and arctic individuals measure from 

 four to five inches, with only a pair or two of leaves. 



2. A. DiolUs ; caule elato folioso, foliis oblongis obtusis molliter pubescentibus oblique 

 venosis denticulatisj floribus 1-3. 



Hab. Alpine rivulets of the Rocky Mountains. Drummond. — In the shape of its foliage, this species has 

 much affinity with the A. montaiia, especially the Europaeau variety; but the stem is leafy (with four or 

 five pairs) all the way up; and the leaves are very flaccid and soft, with lax down. The flowers are re- 

 markably large, and of a full orange yellow, in the dry state. 



3. A, Menziesii ; caule elato, foliis cordatis glubris grosse serratis basi atteiiuatis, inferi- 

 oribus longe petiolatis, superioribus sessilibus, panicula.subtriflora. (Tab. CXI.)

Hab. Alpine woods of the Rocky Mountains, on the east side, Dnimmo?id ; and on the west side, in 

 mountain woods between the Kettle Falls and Spokan River, and in the Blue Mountains. Dout/las.— This 

 appears quite distinct from the preceding, and is very constant in the shape and petiolation of its leaves.
