Vegetative parts: plants tufted or mat-Forming or single isolated shoots, 0.2–0.6 m tall, basal diameter 0.1–3 m, crown diameter 0.1–3 m, with rhizomes or with stolons. Rhizome spreading, unbranched or sparsely branched, culms evenly spaced, 3–6 mm in diam., culms 1–6 mm apart. Fertile culms branching, striate, olivaceous or speckled golden (and brown), 0.2–0.6 m tall, diameter at base 0.6–2.7 mm, diameter at apex 0.5–1.5 mm. Sheaths closely convoluted or loosely convoluted, 10–28 mm long, brown, with or without paler margins; occasionally olivacious, upper 1/3 in colour and texture abruptly different from the base, and soon decaying, apical margins broadly membranous, hyaline shoulders absent, apex, excluding the membranous lobes, acuminate or acute. Sheath-mucro penicellate or awl- or needleshaped, straight and erect, 3–10 mm long, the membranous apex of the sheaths soon drops, leaving a truncate remnant. Males: male inflorescence with indefinite spikelets, Racemose or paniculate, 20–60 mm long, 5–14 mm wide. Male inflorescence spathes caducous, taller than spikelets, cartilaginous, sheath-like. Male flowers not aggregated into spikelets. Male bracts taller than flowers, 4–12 mm long, linear, acute, lax or imbricate, chartaceous or membranous, bract upper margin like body of bract, bract awn minute or absent. Male flower 2–3 mm long. Male tepals sepals and petals the same rigidity, chartaceous or membranous, linear, inner and outer tepals the same length. Male outer lateral tepals as other tepals, glabrous. Anthers 1.5–2.5 mm long, included in the flowers. Pistillode absent. Females: female inflorescence linear or racemose, 10–35 mm long, 4–8 mm wide, with 1 spikelet or 2–5 spikelets (usually spikelet solitary). Female spathes as long as the spikelets or longer than the spikelets, not obscuring spikelet, persistent or caducous, coriaceous. Female spikelet sessile, elliptical or obovate or obtriangular, apex rounded or acute, 10–30 mm long, with 1 flowers, with 4–9 sterile bracts. Female bracts taller than flowers, 10–30 mm long, oblong, acuminate, cartilaginous, apical margin like rest of bract, same as body of bract or darker than body of bract, awn minute or absent or less than half as long as the bract body. Female flower 6–8.5 mm long, with a fleshy pedicel. Female tepals chartaceous or membranous, glabrous and smooth, smaller than nut and not obscuring the nut surface, midrib flush with the tepal body, apices truncate or rounded or obtuse or acute, inner whorl longer than outer or inner and outer whorls the same length. Female outer lateral tepals like other tepals, 2.5–5 mm long. Female odd outer tepal ovate, 2.5–5 mm long. Female inner tepals ovate, 2.5–5 mm long. Staminodes absent. Styles plumose, white or red, 2. Style bases free. Ovary with 1 locule, indehiscent. Fruit: indehiscent fruits with a hard woody ovary wall. Perianth presence on fruits persistent, membranous, shorter than nut. Nut apex smooth, without a distinct cap (without a distinct cap, not smooth- pitted), wall pitted, (4.67–)5.36(–6.17) mm long, (2.67–)3.33(–4) mm diam., shape in side view obovate or oblong, shape in top view round in cross section, brown. Elaiosome present, olivacous, 1.5–3 mm long, more than 0.5 nutlength or less than half as long as nut.
