Penstemon crandallii var. procumbens

Endemic
Basionym: Penstemon procumbens Greene Pl. Baker. 3: 23. 1901
Synonyms: P. crandallii subsp. procumbens (Greene) D. D. Keck
Treatment appears in FNA Volume 17. Treatment on page 103. Mentioned on page 102.

Stems prostrate or decumbent, 2–18 cm, retrorsely hairy. Leaves glabrous or sparsely puberulent, especially along margins, (2–) 4–24 × 2–8 mm; blade obovate to elliptic.


Phenology: Flowering Jun–Jul.
Habitat: Sagebrush shrublands, scrub oak woodlands, spruce woodlands, talus slopes.
Elevation: 2000–3400 m.

Distribution

Colo.

Discussion

Specimens referable to var. procumbens come from Carbon Peak, Kebler Pass, and West Elk Mountains. D. D. Keck (1937) noted the strong resemblance of the type specimen to Penstemon caespitosus subsp. suffruticosus A. Gray (= P. xylus). More material is needed to determine where var. procumbens fits in the P. crandallii/P. caespitosus complex.
