Perennials, (8–) 10–20 (35) cm tall, densely caespitose, without stolons, sparsely ciliate; stems erect, ±stout. Upper cauline leaves 4–5 cm long, 3–4 mm wide; basal leaves 3–5(–7) mm wide. Leaf margin remotely papillose-serrulate. Basal bract usually spreading, overtopping inflorescence. Inflorescence congested, composed of (3–) 5–6 (–8) sessile to subsessile (rarely some pedunculate) clusters; peduncles smooth; clusters usually of 7–10 flowers. Tepals ±lanceolate, gradually tapering to long narrow sharp pointed tips, usually dark brown; outer tepals (2.7–) 3.0–3.5 (–3.7) mm long, ±equalling the inner ones. Anthers (0.8–) 0.9–1.1 mm long, at most 1.5 times longer than the 0.5–0.8 mm long filaments. Style c. 0.6 mm long, shorter than the ovary. Capsule segments usually 2.5–2.8 mm long, shorter than the perianth, ±obovate. Seeds narrowly ovoid, 1.0–1.2 mm long, 0.7–0.8 mm wide; appendages 0.3–0.4 mm long. 2n=36 [12AL + 24BL], fide J.Kirschner, T.Engelskjøn & G.S.Knaben, Preslia 60: 100–101 (1988).
