Leaves: basal and proximal cauline 15–90 × 8–35 mm, blade ovate, base truncate to tapered, margins entire or coarsely dentate, apex acute; cauline 4–7 pairs, short-petiolate or sessile, 10–70 × 8–32 mm, blade cordate to triangular-lanceolate, base tapered or truncate on proximal leaves to connate-perfoliate on distal leaves, margins coarsely dentate, sometimes entire, apex acute. Thyrses interrupted, secund, 10–40(–65) cm, axis glabrous or glandular-pubescent, verticillasters 6–12(–22), cymes 2–8-flowered; proximal bracts depressed-ovate to ovate or triangular, 6–45 × 11–26 mm; peduncles and pedicels spreading to ascending or erect, glabrous or glandular-pubescent.

Discussion
Varieties 3 (3 in the flora).
Penstemon clevelandii is an ancient, stable, diploid hybrid between P. centranthifolius and P. spectabilis (A. D. Wolfe et al. 1998). Penstemon ×parishii A. Gray is a naturally occurring hybrid, also with P. centranthifolius and P. spectabilis as parents; it has been reported from Los Angeles, Riverside, San Bernardino, and San Diego counties, California (D. D. Keck 1937b; Paul Wilson and M. Valenzuela 2002). Keck reported that P. clevelandii var. clevelandii could be distinguished from P. ×parishii by the former’s shorter and narrower corollas, more glandular-pubescent inflorescences, and explanate pollen sacs.
Selected References
