Plants (10–) 20–70 cm tall, forming loose to dense stands; rhizome creeping, ±long-noded, 3–6 mm thick; stems often in dense groups from abbreviated rhizome branches. Cataphylls usually 2–3, very loose, broad, to 8 (rarely to 10) cm long, pale stramineous in distal 2/3–3/4, dull yellowish brown to mid-brown or rarely dull pale castaneous at base, pale stramineous adaxially; lower cataphylls with or without short awn-like blade; uppermost cataphylls usually with well developed blade. Basal leaves 1–2, well developed, terete but usually ±compressed and slightly twisted, 1–2 (–3) mm thick, smooth or irregularly slightly striate, green to greyish green; pith continuous, dense, of astericiform cells. Well developed leaves 5–30 cm long, terete; auricles short, rounded, somewhat cartilaginous. Lower bract often short, 1.5–5 cm long (rarely to 15–30 cm), shorter than to three× as long as inflorescence, with a conspicuously pointed tip. Inflorescence pseudolateral, 1–3 (–5–10) cm long, diffuse or with several loose clusters on short usually flexuose peduncles usually 0.2–0.4 mm thick; flowers usually 5–20. Bracteoles pale stramineous to scarious, sometimes pale castaneous-brown at base, ovate, acute, c. 1.5 mm long. Tepals 3.5–5 mm long, subequal, lanceolate; outer tepals acuminate, with central band greenish to stramineous, usually bordered pale brown to deep castaneous-brown, with broad, scarious margins; inner tepals acute to acuminate, sometimes subobtuse and mucronate. Anthers 1.4–1.6 mm long, much longer than c. 0.4 mm filaments. Capsule 3.5–5 mm long, ±equalling tepals, narrowly oblong-ovoid, subtrigonous, abruptly contracted to 0.3–0.5 mm mucro, castaneous-brown to brown. Seeds ellipsoid to narrowly ovoid, pale brown, 0.8–0.9 × 0.4–0.45 mm, oblong-ovoid; outer seed coat ±loose, finely reticulate.
