Leaves: basal numerous, blade 1.5–6 cm × 3–7 mm, somewhat fleshy, subglabrous; cauline in 1–3 pairs, blade narrowly lanceolate, 1.5–4 cm × 1–5 mm. Inflorescences sometimes forked, 1–3(–4)-flowered. Pedicels erect or angled in flower and erect in fruit, stout, usually elongate, 1–10 cm, densely glandular-pubescent with long purple-septate hairs, ± viscid. Flowers erect; calyx veined, ovate-elliptic to broadly campanulate, 11–14(–18) × 8–13 mm, veins brown or purple, densely glandular-pubescent with purple-septate hairs, lobes ovate-triangular, 2–3 mm, margins broad, membranous; corolla dingy purple-red, 11/3–11/2 times length of calyx, claw equaling calyx, limb obovate, 2-lobed, 2–4 mm. Capsules not contracted at mouth, equaling calyx; carpophore 1–2 mm. Seeds sooty brown, winged, round, flat, 2–2.5 mm diam.; wing inflated, broad, strongly rugose. 2n = 48.
