Vegetative parts: plants tangled, 0.2–0.5 m tall, basal diameter 0.1–1 m, crown diameter 0.1–1 m, compact, without spreading rhizomes or stolons. Fertile culms branching, finely rugulose or finely warty, olivaceous, 0.1–0.5 m tall, diameter at base 0.8–1.2 mm, diameter at apex 0.3–0.5 mm. Sheaths closely convoluted, 4–18 mm long, pale brown, apical margins narrowly membranous or broadly membranous, hyaline shoulders small, rounded or membranous margins continuing behind awn, hyaline shoulder 0.1–0.2 of sheath body length, apex, excluding the membranous lobes, acute. Sheath-mucro penicellate or awl- or needleshaped, straight and erect, 1.5–2 mm long, broad membranous margins reaching to awn. Males: male inflorescence with 2–5 spikelets or 6–10 spikelets, racemose or paniculate, 12–35 mm long, 8–15 mm wide. Male inflorescence spathes persistent, shorter than spikelets, cartilaginous, with broad membranous margins. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong, apex rounded, 6–10 mm, 3–5 mm, with 3–6 flowers, pedicels shorter than the spikelets, terete or angular or flattened. Male bracts taller than flowers, 3.5–6 mm long, oblong or ovate, acuminate, cartilaginous, bract upper margin with honeycombed cells, which eventually decay (upper third of bracts, not sharply delimited from body), bract awn minute or absent. Male flower 2.5–3.5 mm long. Male tepals sepals more rigid than petals, chartaceous, petals membranous, oblong, inner and outer tepals the same length. Male outer lateral tepals conduplicate, keel sparsely villous. Anthers 1.2–1.6 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence paniculate, 10–25 mm long, 5–15 mm wide, with 1 spikelet or 2–5 spikelets. Female spathes shorter than the spikelets, persistent, coriaceous. Female spikelet sessile, elliptical or obovate, apex rounded, 7–11 mm long, with 1–3 flowers, with 3–5 sterile bracts. Female bracts as tall as flowers (with age the apical 1/3 decays, leaving them shorter), 6–9 mm long, oblong or ovate, acuminate, cartilaginous, apical margin with honeycombed cells (most of the bract body), paler than body of bract, awn minute or absent. Female flower 5.5–6.5 mm long, without a fleshy pedicel. Female tepals cartilaginous, keels of lateral sepals sparsely villous, midrib flush with the tepal body, apices acute, inner and outer whorls the same length. Female outer lateral tepals conduplicate, 5.5–6.5 mm long. Female odd outer tepal oblong, 5.3–6.3 mm long. Female inner tepals oblong, 4.7–6 mm long. Staminodes present. Styles feathery, 3. Style bases free. Ovary with 2 locules or 1 locule, dehiscent. Fruit: seed 2.3–2.5 mm long, 1–1.4 mm in diameter, shape in side view elliptical, shape in diameter plano-convex in cross section, tan, smooth; funicular elaiosome present (probably - dried form seems to have a soft funicle).
