Shrubs to 1 dm. Stems multicellular, eglandular-hairy (hairs unbranched) and stipitate-glandular-hairy, glabrate with age. Leaves often clustered toward distal portions of shoots; blade elliptic to obovate, sometimes ovate, 1–3.5 × 0.4–1.5 cm, thin, margins ciliate (hairs stipitate-glandular), plane, apex rounded to obtuse or acute, mucronate, surfaces glandular-hairy. Floral bud-scales (and leaflike inflorescence bracts) stipitate-glandular-hairy. Inflorescences 2–3-flowered, sometimes flowers solitary; axis elongate. Pedicels 1–4.7 cm, stipitate-glandular-hairy; bracteoles 2, green, smaller than leaves. Flowers opening after shoot development, appearing to terminate leafy shoots due to their leaflike bracts; calyx lobes 7–16 mm, stipitate-glandular-hairy; corolla purple, upper 3 lobes with darker spots, 16–25 mm, margins smooth, ± glabrous on outer surface, tube ± absent due to slit between lower 2 lobes, lobes 11–24 mm; stamens unicellular-hairy proximally. Capsules 5–11 mm, unicellular-hairy. 2n = 24, 26.
