Perennials, 9–15 (–30) cm tall, densely caespitose; without stolons; rhizome short; stems erect. Basal leaves densely to subsparsely ciliate, 2.0–3.5 mm wide; cauline leaves usually 2 or 3, with densely papillose-serrulate margin, upper cauline leaves 3.0–5.5 cm long, 2.0–3.0 mm wide. Lower bract usually 3.0–4.0 cm long, overtopping or rarely shorter than inflorescence. Inflorescence composed of 1–2 subsessile and (5–) 7–12 (–18) pedunculate clusters; clusters ±cylindrical, 4–7 × 3–4 mm long, usually (9–) 11–14 (–20)-flowered. Peduncles straight, densely papillose, often with secondary branches, with longest peduncles (including clusters) 2.0–5.5 cm long. Bracteoles 0.8–1.2 mm long, ciliate. Tepals pale greenish to membranous to straw-brown; outer tepals conspicuously longer than inner, 2.0–2.8 mm long, subacuminate. Anthers 0.5–0.6 mm long, ±as long as c. 0.5 mm long filaments; ovary 0.5–0.6 mm long; style 0.2–0.3 mm long; stigma early deciduous, 0.6–0.7 mm long. Capsules obovoid to subglobular, equalling or shorter than perianth; capsule segments 1.6–1.9 mm long. Seeds ovoid, 0.7–0.8 mm long, 0.5–0.6 mm wide; appendage 0.2–0.3 mm long. 2n=12 [12AL], fide J.Kirschner, Thaiszia 2: 28–29 (1992).
