abundant in British Columbia and regions adjacent. It is 
represented in the Canadian Survey collection by all the 
numbers following: 427, in open places near Victoria, Van- 
couver Island, May, 1893, Macoun; 11287, gravelly hill- 
sides, Goldstream, Vancouver Island, 20 May, 1887, Macoun; 
11284, in open woods, Agassiz, British Columbia, 8 May, 
1889, Macoun; 11289, dry woods and banks, Blackwater 
River, B. C., 10 June, 1875, Macoun ; 5219, on grassy banks, 
Spray Avenue, Banff, 30 June, 1891, Macoun; 11281, in dry 
gravelly soil, Crows’ Nest Pass (East of the Lake), 8 July, 1883, 
Dawson.
