 land {Mr. Cormackj Sir Alexander Cochrane) to the alpine Prairies of the Rocky Mountains. DntmmoncL 

 —li. Fort Vancouver, on the Columbia.— My var. /3. entirely a^n-ees M'ith ^vllat is <'ulti\ated in our i^rardcns 

 as the G. macrophyllum, and sufficiently so A^iththe description of authors; hut I do not find that it differi> 

 from the G. strictum, (which is indeed a most variable plant,) except in size.

Hab. Canada. Michaux, Pursh, Lake Huron. Dr. Todd. — I have not myself seen specimens from 



any other pai-t of the British Possessions tlian Lake Iltuon ; hut this is a frequent plant in the United States. 



The G. album, of which 1 have fine specimens from Dr. ToiTey, cannot be distinguished from G. Virginianum; 



the leaves are frequently trifoliolate and pinnate from the same root. Professor Bigelow obsor%'es that there 



> are intermediate states between the two species.
