Annuals. Stems 7–170 cm, not self-supporting, glabrous, eglandular-hairy, or glandular-hairy; branches twining. Leaves opposite proximally, alternate distally; blade ovate to narrowly elliptic, 10–60 × 1–20 mm, surfaces glabrous or hairy. Inflorescences axillary, racemes or flowers solitary. Pedicels 1–4 mm. Flowers cleistogamous and chasmogamous; calyx lobes unequal, glandular-hairy, adaxial lobe 3.5–14 × 1–9 mm; corolla light purple to white, often dark-veined, 8–17 mm, base gibbous, mouth 2–4 mm diam., palate sometimes purple-veined, convex, 3.5–8 mm diam., puberulent. Capsules ovoid, 4–8 mm, glandular-hairy, abaxial locule with 1 pore. Seeds dark-brown to black, 0.7–1.5 mm, tuberculate, reticulate-ridged. 2n = 30.
