Vegetative parts: plants tufted or tangled, 0.13–0.3 m tall, basal diameter 0.05–0.1 m, crown diameter 0.3–0.6 m, compact, without spreading rhizomes or stolons. Fertile culms branching, round (not compressed), smooth or finely warty, 0.13–0.3 m tall, diameter at base 0.6–1.5 mm, diameter at apex 0.2–0.3 mm. Sheaths persistent, with no abscission line, closely convoluted, 4–10 mm long, olive-brown, apical margins narrowly membranous, hyaline shoulders small, rounded or membranous margins continuing behind awn, hyaline shoulder 0.1 of sheath body length, apex, excluding the membranous lobes, acute. Sheath-mucro penicellate, straight and erect, 0.5–1.5 mm long. Males: male inflorescence with 1 spikelet or 2–5 spikelets (rarely more than 1), sparsely paniculate, 5–15 mm long, 3–5 mm wide. Male inflorescence spathes persistent, minute, coriaceous, smaller than the bracts. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, elliptical or ovate, apex acute, 6–9 mm, 2.5–4 mm, with 5–10 flowers, pedicels absent ie spikelets sessile. Male bracts as tall as flowers, 3–3.5 mm long, ovate, acute, cartilaginous, bract upper margin with honeycombed cells, which eventually decay (grading gradually into the cartilaginous body of the bracts), bract awn minute or absent, golden brown below, the apex almost black. Male flower 2.7–3 mm long. Male tepals sepals more rigid than petals, cartilaginous, petals chartaceous, linear, inner and outer tepals the same length. Male outer lateral tepals conduplicate, keel densely villous (and with a hairy patch on odd sepal). Anthers 1.5–1.7 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence with 1 spikelet. Female spathes insignificant, persistent, coriaceous. Female spikelet sessile, obovate, apex rounded, 5–7 mm long, with 1 flowers, with 3–4 sterile bracts. Female bracts shorter than flowers or as tall as flowers, 3–6 mm long, ovate, acute, cartilaginous, apical margin with honeycombed cells, darker than body of bract, awn minute or absent. Female flower 4–6 mm long, without a fleshy pedicel. Female tepals cartilaginous, keels of lateral sepals sparsely villous or keels of lateral sepals densely villous, midrib flush with the tepal body, apices acute, inner and outer whorls the same length. Female outer lateral tepals conduplicate, 4–6 mm long. Female odd outer tepal oblong or ovate, 4–6 mm long. Female inner tepals ovate, 3.5–5.5 mm long. Staminodes present. Styles feathery, white, 3. Style bases free. Ovary with 2 locules, dehiscent. Fruit: seed (1.32–)1.51(–1.88) mm long, (0.88–)1.09(–1.28) mm in diameter, shape in side view oblong, shape in diameter triangular in cross section, brown, colliculate.
