SHORTSPUR COLUMBINE 



AquiUgta brevistyla Hooker 



Shortspur columbine is a rare member of the Crowfoot Family, 

 seldom found by mountain visitors. Its blue coloring is most beauti- 

 ful, and in marked contrast to that of the lemon columbine and red 

 columbine, both of which are familiar plants in the alpine valleys of 

 the Canadian Rockies. 



This species is found from Minnesota and South Dakota to Alberta 

 and Yukon. It is closely related to the European columbine (AquiUgia 

 vulgaris) so often cultivated in our gardens. 



The sketch was made from a specimen obtained in the valley of 

 Healy Creek, ten miles south of Banff, Alberta, Canada, at an altitude 

 of (:>f)oo feet.
