sheets in the herbarium of the Geological Survey of Canada. 

 This examination has forced me to the conclusion that we 

 have no true S. salicifolia in Canada. There are, however, 

 three or four well defined varieties or species of which the 

 most abundant in the east is S. salicifolia, var. lafifolia. Ait., 

 common from Nova Scotia to Lake Superior but not found in 

 the Northwest Territories. The form most nearly approach- 

 ing S. salicifolia is var. lanceolate^, Ait., represented in our 

 herbarium by specimens from Newfoundland west to Prince 

 Albert on the North Saskatchewan. Though the herbarium 

 material is ample no attempt will be made at present to char- 

 acterize the other forms as like some other genera of the 

 Rosacece, Spircea must be studied in the field. The part of the 

 plant which can most easily be made into a herbarium speci- 

 men is not always that most necessary for the proper deter- 

 mination of the species.
