Notes on Some Interesting British Columbian 



Plants. 



By Edith M. Farr. 



The plants on which the following observations are made 

 were collected in the Canadian Rocky Mountains and Sel- 

 kirks during the summers of 1903-04. The flora of these 

 mountains is comparatively unknown and suggests many 

 interesting questions. Although many of the plants seem 

 at first sight to be like the eastern forms, a more careful 

 examination often reveals marked differences, so that one 

 is led to think that possibly many species west of the Con- 

 tinental Divide may vary from the typical eastern forms. 

 At present there is no handbook which covers this special 

 region, but I hope to continue my studies during another 

 summer in the field to such an extent as to warrant the 

 issuing of a Flora containing descriptions and illustrations 

 of at least the more conspicuous plants to be seen at Banff, 

 Lake Louise, Field, Emerald Lake, the Yoho Valley and 

 Glacier, these being the principal places of resort along the 

 line of the Canadian Pacific Railway. 



I wish here to acknowledge my indebtedness to Prof. J. M. 

 Macfarlane for the microscopical details mentioned in the 

 accompanying notes.

 slender, glabrous, simple. Roots filiform, three to four from 

 each node of the filiform rhizome. Leaves, four to eight,
