DRUMMOND WILLOW 



Salix dmmmondiana Barratt 



In the Canadian Rockies, as late summer arrives, this willow is 

 clothed in its most beautiful garb. Each branch is adorned with loose 

 masses of fluffy cotton, consisting of the seeds and the adhering 

 plumes. These masses are blown far and wide by the wind, and if the 

 plants happen to grow near streams, a windrow of cotton often ac- 

 cumulates along their moist margins. Later this is caught by the water 

 and carried far down stream. 



Drummond willow has a narrow range, being confined to Alberta 

 and British Columbia. 



The sketch was made from a specimen that grew at Sheep Creek 

 seventy-five miles by trail from Lake Louise, Alberta, at an altitude 

 of 6,000 feet
