Vegetative parts: plants clumped or tufted, 0.15–0.3 m tall, basal diameter 0.05–0.4 m, crown diameter 0.2–0.4 m, with rhizomes. Rhizome spreading, unbranched or sparsely branched, culms evenly spaced, 3 mm in diam., culms 1–3 mm apart. Fertile culms sparingly branched or branching, finely rugulose or rugose, blue-green, 0.15–0.3 m tall, diameter at base 0.5–0.7 mm, diameter at apex 0.3–0.5 mm. Sheaths closely convoluted, 10–12 mm long, green, eventually turning brown, apical margins narrowly membranous or broadly membranous, hyaline shoulders absent or small, rounded, hyaline shoulder 0.1–0.3 of sheath body length, apex, excluding the membranous lobes, acuminate. Sheath-mucro penicellate or hair-like, straight and erect or twisted, 5–10 mm long. Males: male inflorescence with 2–5 spikelets, racemose, 10–20 mm long, 2–5 mm wide. Male inflorescence spathes caducous, taller than spikelets, chartaceous. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, linear or oblong or undifferentiated, apex rounded or obtuse or acute or undifferentiated, 3–7 mm, 0.5 mm, with 1–2 flowers, pedicels absent ie spikelets sessile. Male bracts as tall as flowers, 1.5–5 mm long, linear or oblong, rounded or obtuse or acute or acuminate, lax, chartaceous or membranous, bract upper margin like body of bract, bract awn minute or absent, poorly developed and very variable. Male flower 3–4 mm long. Male tepals sepals and petals the same rigidity, chartaceous, oblong, inner and outer tepals the same length or inner tepals longer than outer tepals. Male outer lateral tepals as other tepals, glabrous. Anthers 2–2.5 mm long, included in the flowers. Pistillode absent. Females: female inflorescence linear or racemose, 10–20 mm long, 2–5 mm wide, with 2–5 spikelets. Female spathes longer than the spikelets, obscuring spikelet, persistent, coriaceous. Female spikelet sessile, oblong or elliptical, apex rounded, 5–7 mm long, with 1 flowers, with 0–3 sterile bracts. Female bracts shorter than flowers or as tall as flowers, erect, 5–6 mm long, oblong, rounded or acute, chartaceous, apical margin like rest of bract, same as body of bract, awn minute or absent. Female flower 5–6 mm long, without a fleshy pedicel. Female tepals chartaceous, glabrous and smooth, at least as tall as nut, wrapped around it and obscuring the surface, midrib flush with the tepal body, margins entire, apices rounded or obtuse or acute, inner and outer whorls the same length. Female outer lateral tepals like other tepals, 5–6 mm long. Female odd outer tepal oblong, 5–6 mm long. Female inner tepals oblong, 1–2 mm long. Staminodes present. Styles feathery, white, 2. Style bases free. Ovary with 1 locule, indehiscent. Fruit: indehiscent fruits with a softer ovary wall. Perianth presence on fruits persistent, membranous, as tall as nuts. Nut apex smooth, without a distinct cap, wall smooth, 4 mm long, 1 mm diam., shape in side view oblong, shape in top view round in cross section, tan, mode of seed release for nutted plants unknown. Elaiosome absent.
