Vegetative parts: plants clumped or tangled or single isolated shoots, 0.2–0.5 m tall, basal diameter 0.1–0.2 m, crown diameter 0.3–0.5 m, with stolons. Fertile culms sparingly branched or branching, smooth or finely rugulose or finely warty, olivaceous, 0.2–0.5 m tall, diameter at base 0.7–1.2 mm, diameter at apex 0.3–0.6 mm. Sheaths closely convoluted, 10–25 mm long, golden-brown, apical margins narrowly membranous or broadly membranous (only towards the apices), hyaline shoulders membranous margins continuing behind awn (fused to the awn), hyaline shoulder 0.2–0.4 of sheath body length, apex, excluding the membranous lobes, acuminate. Sheath-mucro awl- or needleshaped, straight and erect, 3–6 mm long, upper 1/3 of sheath with broad membranous margins, tapering into the awn. Males: male inflorescence with 1 spikelet or 2–5 spikelets (rarely more than 2), racemose, 20–50 mm long, 10–15 mm wide. Male inflorescence spathes caducous, minute, cartilaginous. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong or elliptical, apex rounded, 13–18 mm, 6–15 mm, with 5–10 flowers, pedicels absent ie spikelets sessile. Male bracts shorter than flowers or as tall as flowers, 8–10 mm long, oblong or ovate, acute, cartilaginous, bract upper margin membranous, thinner texture than the body (almost one third of bract length), bract awn minute or absent, lower two thirds pale brown, cartilaginous, upper one third membranous. Male flower 3.5–4.5 mm long. Male tepals sepals more rigid than petals, cartilaginous, petals membranous, oblong, inner tepals shorter than outer tepals. Male outer lateral tepals conduplicate, glabrous or keel sparsely villous (hardly visible). Anthers 2–2.5 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence racemose, 20–50 mm long, 5–7 mm wide, with 1 spikelet or 2–5 spikelets. Female spathes shorter than the spikelets (like bracts), persistent, coriaceous. Female spikelet sessile, elliptical, apex acute, 10–20 mm long, with 5–12 flowers, with 0 sterile bracts. Female bracts at least twice as long as flowers, 8–9 mm long, oblong, acute, cartilaginous, apical margin membranous (upper third, often transparent), paler than body of bract, awn minute or absent. Female flower 3.2–4 mm long, without a fleshy pedicel. Female tepals chartaceous (sepals) or membranous (petals), glabrous and smooth or lateral sepal wings of fused hair, giving dentate appearance, midrib flush with the tepal body, apices rounded, inner whorl shorter than outer. Female outer lateral tepals keeled or winged, wings lacerated or deeply lobed, as wide as body or wider than body, hidden by bracts, or bracts are shorter than flowers, 3.3–4.4 mm long. Female odd outer tepal oblong, 3–4 mm long. Female inner tepals elliptical, 2–3 mm long. Staminodes present. Styles feathery, white, 3. Style bases free. Ovary with 1 locule, dehiscent.
