Herbs. Stems ascending to erect, (30–)40–100 cm, viscid glandular-pubescent, not glaucous. Leaves basal and cauline, opposite, viscid glandular-pubescent, not glaucous; basal and proximal cauline 25–120(–260) × 7–20(–65) mm, blade elliptic to lanceolate, base tapered, margins entire, subentire, or irregularly serrate to dentate, apex acute to acuminate; cauline 4–10 pairs, sessile, 32–80(–120) × 12–45 mm, blade ovate to obovate, elliptic, or lanceolate, base tapered to cordate-clasping, margins entire or subentire to irregularly serrate to dentate, apex obtuse to acute or acuminate. Thyrses interrupted, cylindric, (5–)8–31 cm, axis viscid glandular-pubescent, verticillasters 3–7, cymes (1 or)2–8-flowered, 2 per node; proximal bracts ovate, 18–60 × 11–44 mm; peduncles and pedicels ascending to erect, viscid glandular-pubescent. Flowers: calyx lobes lanceolate, 9–15 × 2.3–3.8 mm, viscid glandular-pubescent; corolla lavender to bluish lavender or purple, with dark violet nectar guides, ampliate, (28–)30–40 mm, glandular-pubescent externally, sparsely to moderately white-pubescent internally abaxially, tube 9–11 mm, throat gradually inflated, 12–15 mm diam., rounded abaxially; stamens included, filaments glabrous, pollen sacs parallel, 1.6–2.2 mm, distal 1/2 indehiscent, sides glabrous, sutures denticulate, teeth to 0.2 mm; staminode 22–26 mm, exserted, 0.8–1 mm diam., glabrous, rarely distal 2–4 mm sparsely pubescent, hairs yellow, to 0.4 mm; style 20–26 mm. Capsules 9–13 × 5–6.5 mm.

Discussion

Varieties 2 (2 in the flora).

Two allopatric varieties of Penstemon glandulosus have been distinguished based on basal leaf morphology. Leaf margins occasionally vary from entire to serrate or dentate among individuals in some populations, but the general pattern of leaf variation does appear to be geographically correlated.

Selected References

None.
