WOOLLY ARNICA 



Arnica tomentosa Macoun 



Woolly arnica is one of many species of this genus, which belongs 

 to the Aster Family. It is a graceful perennial with large bright yel- 

 low flower heads produced at the ends of the stems. Like other parts 

 of the plant the leaves are conspicuously woolly, hence the appropri- 

 ateness of the name given to it. We found this arnica growing high 

 on the mountainside where it maintained a precarious foot-hold in 

 shallow soil in crevices of limestone rocks. 



This species has a narrow range, occurring only in Alberta and 

 British Columbia. 



The plant illustrated was gathered in the valley of the Siffleur 

 River, British Columbia, at an altitude of 5,000 feet.
