Vegetative parts: plants clumped or tangled, 0.15–0.4 m tall, basal diameter 0.01–0.03 m, crown diameter 0.02–0.05 m, compact, without spreading rhizomes or stolons. Fertile culms sparingly branched or branching, finely rugulose, olivaceous, 0.15–0.4 m tall, diameter at base 0.3–0.6 mm, diameter at apex 0.2–0.5 mm. Sheaths closely convoluted, 6–10 mm long, reddish-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 or obtuse. Sheath-mucro penicellate, straight and erect, 1–2 mm long. Males: male inflorescence with 2–5 spikelets or 6–10 spikelets, sparsely paniculate, 10–140 mm long, 3–10 mm wide. Male inflorescence spathes persistent, like the floral bracts, chartaceous or cartilaginous, margins soon decaying. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, elliptical or obovate, apex rounded or obtuse or acute, 4–6 mm, 1.5–2 mm, with 3–4 flowers, pedicels absent ie spikelets sessile or longer than the spikelets, terete or angular. Male bracts as tall as flowers, 2–3 mm long, oblong or elliptical or ovate, rounded or obtuse, chartaceous or cartilaginous, bract upper margin membranous, thinner texture than the body (and at anthesis somewhat decayed), bract awn minute or absent or less than half as long as the bract body, due to decay of apical margin the flowers emerge above the bracts. Male flower 2.5–2.7 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. Anthers 0.8–1 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence sparsely paniculate or racemose, 4–100 mm long, 4–10 mm wide, with 1 spikelet or 2–5 spikelets. Female spathes like floral bracts, persistent, chartaceous or cartilaginous. Female spikelet sessile or pedicel sparsely branching, obovate or obtriangular, apex truncate, 4–5 mm long, with 1 flowers, with 4–7 sterile bracts. Female bracts shorter than flowers, 1.5–2.5 mm long, square, rounded, chartaceous or cartilaginous, apical margin membranous, same as body of bract, awn minute or absent. Female flower 3–3.5 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 or inner whorl shorter than outer. Female outer lateral tepals like other tepals, 2.5–3.5 mm long. Female odd outer tepal oblong or ovate, 2.5–3.5 mm long. Female inner tepals ovate, 2–3 mm long. Staminodes present. Styles feathery, 3. Style bases free. Ovary with 3 locules, dehiscent. Phenology, Distribution and Ecology: seed release November; Before next cohort of flowers flower.
