YELLOW PENTSTEMON 



Pentstemon confertus Douglas 



Yellow pentstemon is a graceful member of the Figwort Family. 

 In congenial surroundings it is very plentiful, although inconspicu- 

 ous on account of the pale coloring of its flowers, which are grouped 

 in several whorls along the stem. Altitude affects the plant greatly; 

 in the lower valleys it may grow to a height of two feet, but at a 

 high elevation the stem is only a few inches tall. Yellow flowers are 

 rare among the pentstemons, which are represented in the Rocky 

 Mountains by a number of species, most of them with white or purple 

 blossoms. 



This pentstemon extends from Wyoming to California, and north- 

 ward to Alberta and British Columbia. 



The plant sketched grew in the valley of Cataract Creek near Hec- 

 tor, British Columbia, at an altitude of 6,000 feet.
