Perennials, 5–25 cm tall, loosely caespitose; rhizome creeping, covered with scales, sometimes densely branching and clustered, 1.0–2.0 mm in diam., with sterile shoots terminated by leaf rosettes. Stem terete, grooved. Cataphylls 3–4, sometimes with remains of old leaves at base. Basal leaves 2–3, flat, ridged beneath, grass-like, 1.0–6.0 cm long including sheath, 0.8–3.0 mm wide; sheath 0.5–3.0 cm long; auricles ±absent. Cauline leaves 0 (–1), 1.0–4.0 cm long, 2.0–3.0 mm wide, shorter than inflorescence. Lower bract longer than or sometimes equalling flowers, linear-lanceolate, 1.0–4.5 cm long, 2.3–4.0 mm wide, leaf-like, ridged beneath, grass-like, grass-green, castaneous at base. Inflorescence terminal to ±pseudolateral, of 1–2 (–3) subcongested 4–10-flowered heads subtended by 2 bracts, 0.8–2.0 cm wide, castaneous-brown; capitulum bract linear-lanceolate to lanceolate, 0.5–4.5 cm long, 2.0–4.0 mm wide; sheath-like bract on peduncle, membranous, lanceolate, 0.5–1.0 cm long. Flowers 1.0–1.5 cm long, 2.5–3.5 mm wide; pedicels 0.6–4.5 mm long. Tepals ovate-lanceolate, subequal; inner tepals slightly longer, 5.0–8.0 mm long, 0.9–1.4 mm wide; outer tepals 4.5–7.7 mm long, 0.8–1.3 mm wide, castaneous-brown. Stamens 6, not exserted, 2.7–4.5 mm long; anthers longer than filaments, linear-elliptic, pale yellow, 1.8–3.0 mm long; filaments 0.9–1.5 mm long; style 1.5–2.2 mm long; stigmas 3.0–4.0 mm long, red; ovary ovoid-trigonous, 2.5–3.3 mm long, 1.0–1.5 mm wide. Capsule ±ovoid, rostrate, longer than perianth. Seeds ellipsoid, 2.5–3.0 mm long including two appendages. Fig. 73.
