Vegetative parts: plants mat-Forming, 0.2–0.5 m tall, basal diameter 0.5–3 m, crown diameter 0.5–3 m, with rhizomes. Rhizome spreading, unbranched or sparsely branched, culms evenly spaced, 1–6 mm in diam. (usually 2–4), culms 2–10 mm apart. Fertile culms unbranched, round (not compressed), solid or with a small central cavity, smooth or finely rugulose, olivaceous, 0.2–0.5 m tall, diameter at base 0.4–1 mm, diameter at apex 0.3–0.8 mm. Clusters of sterile branches at the nodes of the fertile branches absent. Sheaths more than 1 per culm, dropping off, with an abscission line present, loosely convoluted, 10–30 mm long, margins entire, light to reddish-brown with tan margins, upper 1/3 in colour and texture similar to the lower 2/3, apical margins narrowly membranous, hyaline shoulders absent, apex, excluding the membranous lobes, obtuse or rounded. Sheath-mucro absent or penicellate, straight and erect, 1–2 mm long. Males: male inflorescence with 21–50 spikelets or 50–100 spikelets, paniculate, 10–70 mm long, 5–25 mm wide. Male inflorescence spathes caducous, taller than spikelets, cartilaginous. Male spathellae conspicuous, 5–10 mm long. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, undifferentiated, apex undifferentiated, 3–4 mm, 2–3 mm, with 3–4 flowers, pedicels shorter than the spikelets or as long as the spikelets, terete or angular. Male bracts shorter than flowers, 0.8–1.3 mm long, ovate or orbicular (quite broad), rounded, chartaceous, bract upper margin like body of bract, bract awn minute or absent. Male flower 1.3–2 mm long. Male tepals sepals and petals the same rigidity, cartilaginous, oblong or elliptical or ovate (outer tepals ovate and inner tepals elliptical or oblong), inner tepals longer than outer tepals. Male outer lateral tepals as other tepals, glabrous. Anthers 1–1.5 mm long, included in the flowers. Females: female inflorescence interrupted or linear, 12–80 mm long, 5–15 mm wide, with 1 spikelet or 2–5 spikelets or 6–10 spikelets. Female spathes longer than the spikelets, obscuring spikelet, persistent, cartilaginous. Female spathellae conspicuous, 4.5–12 mm long. Female spikelet pedicel sparsely branching, undifferentiated, apex undifferentiated, 2–4 mm long, with 1–5 flowers, with 0 sterile bracts. Female bracts shorter than flowers, erect, 1–1.5 mm long, ovate, rounded or obtuse or acute, cartilaginous, apical margin like rest of bract, same as body of bract, awn minute or absent. Female flower 2–2.3 mm long, without a fleshy pedicel, six tepals. Female tepals cartilaginous, glabrous and smooth, at least as tall as nut, wrapped around it and obscuring the surface, midrib raised, margins entire, apices obtuse, inner and outer whorls the same length. Female outer lateral tepals conduplicate, 1.5–2 mm long. Female odd outer tepal oblong or elliptical, 1.5–2 mm long. Female inner tepals oblong or elliptical, 1.5–2 mm long. Staminodes present. Styles feathery, white, 3. Style bases free. Ovary with 1 locule, indehiscent. Fruit: indehiscent fruits with a softer ovary wall. Perianth presence on fruits persistent, papery to leathery, not winged. Nut apex smooth, without a distinct cap, wall smooth, (1.24–)1.69(–2.08) mm long, (0.8–)1.07(–1.36) mm diam., shape in side view ovate, shape in top view elliptical in cross section, brown. Elaiosome absent.
