Vegetative parts: plants tufted (possibly tangled, recorded as forming a dense growth), 0.3–0.5 m tall. Fertile culms unbranched, compressed (rather obscurely), smooth or finely rugulose, olivaceous, 0.3–0.5 m tall, diameter at base 0.1–0.2 mm, diameter at apex 0.05–0.2 mm. Sheaths closely convoluted, 5–15 mm long, brown, apical margins narrowly membranous, hyaline shoulders membranous margins continuing behind awn, hyaline shoulder 0.01 of sheath body length, apex, excluding the membranous lobes, acute. Sheath-mucro penicellate, straight and erect, 1–4 mm long. Males: male inflorescence with 1 spikelet or 2–5 spikelets, sparsely paniculate, 15–50 mm long, 3–15 mm wide. Male inflorescence spathes persistent, like the floral bracts, coriaceous. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, elliptical or obovate or orbicular, apex rounded, 2.5–4 mm, 1–2.5 mm, with 3–4 flowers, pedicels absent ie spikelets sessile. Male bracts shorter than flowers or as tall as flowers, 1.9–2.2 mm long, oblong or square, obtuse, chartaceous, bract upper margin like body of bract, bract awn minute or absent, apical parts soon decaying. Male flower 1.8–2.2 mm long. Male tepals sepals more rigid than petals, cartilaginous, petals membranous, oblong, inner and outer tepals the same length. Male outer lateral tepals conduplicate, glabrous. Anthers 0.8–1 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence sparsely paniculate, 5–80 mm long, 2–30 mm wide, with 2–5 spikelets. Female spathes insignificant or shorter than the spikelets, persistent, coriaceous. Female spikelet sessile, orbicular, apex rounded, 3–4 mm long, with 1 flowers, with 2–5 sterile bracts. Female bracts shorter than flowers, 1–1.8 mm long, oblong or square, truncate or obtuse, chartaceous, apical margin membranous or with honeycombed cells, paler than body of bract, awn minute or absent. Female flower 2–2.5 mm long, without a fleshy pedicel. Female tepals cartilaginous, glabrous and smooth, midrib flush with the tepal body, apices acute, inner and outer whorls the same length. Female outer lateral tepals like other tepals, 2–2.5 mm long. Female odd outer tepal oblong, 2–2.5 mm long. Female inner tepals ovate, 1.8–2.2 mm long. Staminodes present. Styles feathery, 3. Style bases free. Ovary with 3 locules, dehiscent. Fruit: seed 1.2–1.4 mm long, 1–1.1 mm in diameter, shape in side view elliptical, shape in diameter triangular in cross section, brown, colliculate.
