Leaves: proximalmost opposite, distalmost alternate, sometimes opposite nearly to inflorescence, erect to ascending; stipular glands absent; blade narrowly elliptic to oblanceolate, 8–27 × 1.2–5.6 mm, margins entire, not ciliate, apex acute; internal venation shown by transmitted light.

Flowers: sepals persistent, lanceolate, 2–3 mm, margins not scarious, entire, or inner and rarely outer sparsely glandular-toothed, apex sharp-pointed; petals yellow, obovate, 4–7 mm; stamens 3 mm; anthers 0.5–1 mm; staminodia absent; styles distinct, 1.5–2.5 mm; stigmas capitate. Capsules turbinate, 2–3 × 2–2.3 mm, apex acute or obtuse, dehiscing freely into 10, sharp-pointed 1-seeded segments, segments persistent on plant, false septa incomplete, proximal margins sparsely but conspicuously ciliate. Seeds 1.3–1.8 × 0.6–0.9 mm. 2n = 36.
