COLUMBIA CLEMATIS 



Clematis columbiana (Nuttall) Torrey and Gray 



FRUIT OF PLATE 99 



The fruits of the Columbia clematis, although not so conspicuous 

 as the flowers, are quite as beautiful. The silky tails attached to the 

 "seeds" of the loose heads become feather-like as they ripen. The soft 

 shades of green grow paler and finally turn silvery gray, when the ripe 

 fruits are loosened from the parent stem and carried away by the wind. 



Columbia clematis extends from Utah and Colorado northward to 

 Alberta and British Columbia. 



The specimen sketched was found in August in the Horse Thief 

 Valley, Selkirk Mountains, British Columbia, twenty miles west of 

 Athelmere, at an altitude of 3,500 feet.
