Perennials, c. 1–5 cm tall, dwarf, mat-forming; rhizome creeping-ascending, thin, long-noded, c. 0.3–0.4 mm in diam., distally branched, with 3 to several leaves on each branch. Leaves often densely crowded, to 5 cm long, 0.2–0.5 mm in diam., unitubular, ±terete, perfectly septate, ±equalling stem; sheaths ±loose, 3–4-veined on each side, broadly bordered membranous; auricles broad, obtuse, c. 0.3–0.4 mm long. Lower bract leaf-like, 0.4–1.5 cm long, with loose sheath, ±exceeding inflorescence. Inflorescence of 1 or rarely 2 heads, usually 2–4-flowered. Capitulum bracts broadly ovate, acute, membranous to scarious, to c. 2 mm long. Tepals ±unequal; outer tepals shorter, broadly lanceolate, 1.9–3.0 (–3.7) mm long; inner tepals ovate-lanceolate, acute to ±obtuse, longer than or equalling the outer ones, reddish castaneous with darker tip, broadly bordered membranous, with central band greenish to brownish. Stamens 6, often longer than tepals; anthers 0.6–1.0 (–1.5) mm long; filaments c. 1.5–2.2 mm long; style difficult to distinguish from capsule top, c. 0.5–0.7 mm long; stigmas 0.7–1.0 mm long. Capsule broadly ellipsoid to ovoid, trigonous distally, subabruptly narrowing into a subconical 0.5–1.0 mm rostrum, 2.5–3.8 mm long, golden brown to castaneous, slightly exceeding perianth. Seeds ellipsoid-ovoid, apiculate, 0.4–0.6 × 0.25 mm, regularly reticulate, transversally lineolate; appendages absent.
