(1208.) A. Senjavinensis, Bess. 

 Kotzebue Sound. (Beechy.~) 



(1209.) A. biennis, Willd. 



This species has its home in the west where it is very abundant in 

 the valleys of all the rivers and s'mall streams. Of late it has been 

 reported from all the eastern provinces, and is rapidly spreading by 

 means of the railways to every part of the country. From Hudson 

 Bay to the McKenzie River. (Richardson.} Dry interior of British 

 Columbia. (Dawson.) 



(1210.) A. frigida, Willd. Pasture Sage Brush. 



A. frigida, Willd. Var. Gmelinana, Bess. Hook. Fl. L, 321. 

 Very abundant on dry exposed hills and river banks from Manitoba 

 westward to the Rocky Mountains, and northwards to Peace River. 

 West and south of the Cypress Hills this species is very common and 

 makes up with Eurotia lanata much of the winter cattle feed in those 

 districts. At Cornwall's, in the interior of British Columbia, where 

 there is scarcely a blade of grass this plant produces abundance of 

 herbage and is invaluable as a winter food plant. Both in British 

 Columbia and east of the rockies, in the grazing country, this plant will 

 yet be highly prized for its heat producing qualities during the coldest 

 winter weather. Its northern limit as far as known to me is the 

 northern bank of Peace River in Lat. 58. Mackenzie River. (McGill 

 Coll. Herb.)
