PRAIRIE PENTSTEMON 



Pentstemon erianthera Pursh 



Prairie pentstemon is one of a large genus of plants, embracing 

 about one hundred and forty species, all of which are natives of North 

 America. Wherever present they are likely to be found in great 

 numbers, especially in the West, where they are very conspicuous. This 

 species grows in small clumps on dry hillsides. Its large flowers are 

 wonderfully varied in coloration, ranging from blue, through various 

 shades of dull purple, to pale pink. They belong in the Figwort Family. 



The prairie pentstemon may be found from Nevada, Nebraska, and 

 North Dakota to British Columbia and Washington. 



The specimen sketched was obtained near Sinclair Hot Springs, in 

 the Columbia River Valley, British Columbia, at an elevation of ^,500 

 feet.
