 (Hook. Arct. PI.} On the western prairie region and in British Colum- 

 bia a form which, in some respects, approaches A. alpina is very com- 

 mon. It seems to be the A. dioica of Eaton in King's Report of the 

 40th parallel, but is not the A. dioica of the English botanists. It is prob- 

 ably the prairie form of A. alpina, which indeed a late communication 

 from Dr. Gray would indicate. Our plant may be the var. parvifolia, 

 Ton*. & Gray, which is not referred to by late writers.
