41. Penstemon comarrhenus A. Gray. 
Penstemon comarrhenus A. Gray, Proc. Amer. Acad. 12: 81. 1876 ‘‘Common in 
Utah, especially southward, coll. by Gordon, E. W. Emerson, Mrs. Thompson, Siler 
and recently by L. F. Ward.”’ According to a memorandum by Mr. J. F. Macbride 
the specimen of Gordon, of which but a fragment is in the Gray Herbarium, is P. 
strictus Benth. This fails to answer the original description of P. comarrhenus. Of the 
remaining specimens cited, that of Ward was evidently particularly studied, and, 
as this fully answers the description, it may be considered as the type. Isotype 
seen in herbarium of Columbia University at the New York Botanical Garden. 
Rocky or gravelly sagebrush slopes, at altitudes of 1,400 to 2,600 (3,000) meters 
Upper Sonoran and Submontane zones; flowering from late June to early August. 
Mesas in Colorado drainage and westward, western Colorado and central Utah.
