34. Penstemon cyananthus Hook. 
Penstemon cyananthus Hook. in Curtis’s Bot. Mag. 75: pl. 4464. 1849. “‘It is 
* * * an inhabitant of * * * the upper valleys of the Platte River in the 
Rocky Mountains, where seeds were collected by Mr. Burke. These seeds were reared 
by Messrs. Lucombe, Pince and Co., in whose Exeter nursery the plants flowered 
beautifully * * * in May 1849.’ Type not seen or verified. 
Penstemon glaber cyananthus A. Gray, Proc. Amer. Acad. 6: 60. 1862-63. 
Varies in width of leaf and size of flowers, Southward (at Mount Nebo) specimens 
occur with more scarious calyx lobes, possibly approaching P. cyananthus longiflorus. 
Mostly gravelly or rocky soil, sagebrush slopes, and openings in mountain woods, 
at altitudes of (1,300) 1,500 to 3,000 meters; Submontane and Montane zones, at times 
descending and ascending from these; flowering from late May to mid-August. Hills 
and mountains from southwestern Montana southward to Piute County, Utah; 
abundant in the Wasatch Range.

34a. Penstemon cyananthus subglaber (A. Gray) Pennell. 
Penstemon fremontii subglaber A. Gray, Syn. Fl. 2!: 262.1878. ‘Idaho,’’ in moun- 
tains near Fort Hall, Burke. Type in Gray Herbarium, verified by Mr. J. F. Mac- 
bride, who in a letter says of it, ‘The leaves are narrower than usual in P. cyanan- 
thus.’”’ A corolla sent me shows it to be this form. 
Stems puberulent below, frequently for most of their length; leaves prevailing 
lanceolate, the largest stem leaves 6 to 7 cm. long, 1 to 1.5 cm. wide, more densely 
puberulent; corolla about 20 mm. long; capsule 8 to 10 mm. long. Otherwise as 
in the species. 
Dry sagebrush slopes, at altitudes of 1,500 to 2,100 meters; Submontane Zone; 
flowering in July and early August. Hills and lower mountain slopes, western 
Wyoming, eastern Idaho, and northwestern Utah. Probably grades into the species. 
Wyomina: Lincoln: Spread Creek, Tweedy 231 (Y). 
1 More puberulent on stem, although glabrous above.
