Rhizomes with spherical or elongate tuberous thickenings 0.5–2.5 cm. Stems 4-angled, 12–45 (–60) cm, glabrous or stipitate-glandular throughout or at least in inflorescence, often densely so. Leaf-blades linear to linear-lanceolate or broadly lanceolate, (1.5–) 2–10 (–15) × 0.2–1.5 (–2) cm, margins flat to briefly revolute, ± smooth or granular to serrulate, glabrous or stipitate-glandular. Inflorescences open cymes, flowers often proliferating with age. Pedicels recurved to reflexed from base in fruit, uniformly stipitate-glandular. Flowers: sepals lanceolate to narrowly ovate, 3–5.5 (–7) × 0.8–2 mm, stipitate-glandular, often densely so; petals 7–9.5 × 3–4 mm, apex notch 1–2 mm deep, lobes broadly rounded; anthers 10, purple; styles 3.5–4.5 mm; stigmas terminal, 0.1–0.2 mm. Capsules 4.5–5 mm. Seeds 1–3, reddish-brown, broadly elliptic, ± plump, 2–3.4 mm; tubercles conic to elongate, rounded. 2n = 96.


Phenology: Flowering summer.
