related to the Foxglove of the garden, though few of the American 
species are as yet cultivated. The flowers of the Pink Beard-tongue 
are rose-purple or pink and grow on stiff stems 1-2 ft. high. They may 
be found on dry plains, foothills, hills and mountains at 5000-9000 ft. 
and bloom in early summer.

flowers, though sometimes pale yellowish or whitish ones occur. They 
are ornamented with darker longitudinal stripes and bloom in midsum-

altitudes the stems are dwarfed and attain no more than 4 in. in height, 
while ordinarily they grow to 3 ft.

and in the mountains at 4000-10000 it.

hillsides and mountains at 5000-9000 ft. The stems are usually quite 
tall, 2-6 ft., and the flowers bloom in early summer. This Pentstemon
