Perennials 12–30 cm tall, densely caespitose, hairy; base thick, with extravaginal erect shoots; stolons absent. Basal leaves usually 5–10 cm long, 3.5–5.0 mm wide; cauline leaves 1 or 2, 3.5–6.0 cm long, 2.0–3.0 mm wide; all leaves acute, rarely subobtuse, with margins ±smooth to sparsely papillose, sparsely ciliate. Lower and middle bracts castaneous-membranous, with prominent veins, aristate, ciliate, up to 1.5 cm long; upper bracts c. 5 mm, similar to tepals. Inflorescence erect to suberect, rarely slightly nodding, usually interrupted at base, ‘echinate’ with erecto-patent acute bracts, usually 1.5–2.0 (–3.0) cm long, usually of 3–7 few-flowered clusters subtended by conspicuous middle bracts. Bracteoles acuminate, membranous, 2.5–3.0 mm long. Tepals glabrous to sparsely ciliate, pale to castaneous brown at base, membranous-scarious above, acuminate-aristate, ±unequal; outer tepals 3.5–4.8 mm long; inner tepals 2.7–3.7 mm long. Stamens 6; anthers (0.7–) 0.8–1.2 (–1.5) mm long; filaments 0.4–0.6 mm long; style 0.5–0.6 mm long; stigmas 1.5–2.0 mm long. Capsule ovoid, subacute, deep castaneous, shorter than perianth; capsule segments 2.4–2.9 mm long. Seeds [unripe] 1.5–1.7 mm long, c. 1 mm wide; appendage indistinct, c. 0.1 mm long, fibrillate.
