Notes on the Flora of Canada. 



JAMES M. MACOUN- 



During the season of 1890 a considerable number of plants 

 were discovered in various parts of Canada that were either 

 new to the Dominion or were of sufficiently rare occurrence 

 to be worthy of note. Except when otherwise mentioned all 

 the plants in this list were collected by Prof. Macoun and 

 myself in British Columbia. The asterisk (*) after the name 

 of a plant signifies that it had not before been found in 

 Canada. 



I. Thalictrum Fendleri ENGELM.* — Very abundant in low 

 grounds at Kicking Horse Lake, Rocky Mts.
