Vegetative parts: plants mat-Forming or tangled, 0.2–1 m tall, basal diameter 0.2–1 m, crown diameter 0.2–1 m, compact, without spreading rhizomes or stolons (possibly with stolons, not enough material seen). Fertile culms branching, compressed. Margins of compressed culms ribbed distinct rib present. Fertile culms smooth or finely rugulose, green, 0.2–1 m tall, diameter at base 0.2–0.5 mm, diameter at apex 0.1–0.4 mm. Branch axil indumentum present. Sheaths persistent, with no abscission line, closely convoluted, 3–10 mm long, green, apical margins narrowly membranous, hyaline shoulders membranous margins continuing behind awn, hyaline shoulder 0.1 of sheath body length, apex, excluding the membranous lobes, acute. Sheath-mucro awl- or needleshaped, straight and erect, 1–3 mm long. Males: male inflorescence with 6–10 spikelets or 11–20 spikelets, sparsely paniculate or racemose or paniculate, 30–70 mm long, 3–50 mm wide. Male inflorescence spathes persistent, shorter than spikelets or as tall as spikelets, coriaceous, similar to leaves. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong or ovate, apex rounded, 2.5–4 mm, 1.5–3 mm, with 1–3 flowers, pedicels absent ie spikelets sessile. Male bracts taller than flowers, 2–3 mm long, ovate, acute, cartilaginous, bract upper margin like body of bract, bract awn minute or absent. Male flower 1.5–2.5 mm long. Male tepals sepals more rigid than petals, chartaceous, petals chartaceous, linear, inner tepals shorter than outer tepals or inner and outer tepals the same length. Male outer lateral tepals conduplicate or as other tepals, glabrous. Anthers 0.9–1.1 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence with 1 spikelet. Female spathes as long as the spikelets or longer than the spikelets, not obscuring spikelet, persistent, coriaceous. Female spikelet sessile, obovate, apex truncate or rounded, 3–3.5 mm long, with 1 flowers, with 0–1 sterile bracts. Female bracts as tall as flowers or taller than flowers, 2.5–3.5 mm long, ovate, acute or acuminate, coriaceous, apical margin like rest of bract, same as body of bract, awn minute or absent or less than half as long as the bract body. 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 ovate, 2–2.5 mm long. Female inner tepals ovate, 2–2.5 mm long. Staminodes present. Styles feathery, white, 3. Style bases free. Ovary with 1 locule, dehiscent. Fruit: seed (0.8–)1.03(–1.16) mm long, (0.8–)0.92(–1.08) mm in diameter, shape in side view elliptical, shape in diameter triangular in cross section, tan, brittle, white ornamentation.
