Vegetative parts: plants single isolated shoots or forming long lines of culms, 0.15–0.2 m tall, basal diameter 0.01–0.2 m, crown diameter 0.01–0.2 m, with rhizomes. Rhizome spreading, unbranched or sparsely branched, culms evenly spaced, 2–3 mm in diam., culms 5–10 mm apart. Fertile culms unbranched, striate, olivaceous, 0.15–0.2 m tall, diameter at base 0.3–1 mm, diameter at apex 0.5–1 mm. Sheaths persistent, with no abscission line, closely convoluted, 10–15 mm long, pale brown, with golden speckles, apical margins coriaceous, like the rest of the body or narrowly membranous, hyaline shoulders absent, apex, excluding the membranous lobes, acute or rounded. Sheath-mucro penicellate, straight and erect, 0.75–2 mm long. Males: male inflorescence with 1 spikelet. Male inflorescence spathes persistent, shorter than spikelets, cartilaginous. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, elliptical, apex acute, 7–10 mm, 2–3 mm, pedicels absent ie spikelets sessile. Male bracts shorter than flowers, 7–9 mm long, ovate, obtuse, chartaceous, bract upper margin like body of bract, bract awn less than half as long as the bract body, imbricate, obscuring the flowers. Male flower 6 mm long. Male tepals sepals and petals the same rigidity, chartaceous, square. Male outer lateral tepals conduplicate, glabrous. Anthers 3 mm long, exserted from the flowers. Females: female inflorescence with 1 spikelet. Female spathes shorter than the spikelets, persistent, cartilaginous. Female spikelet sessile, elliptical or obovate, apex acute, 7–10 mm long, with 1 flowers, with 3–4 sterile bracts. Female bracts taller than flowers, erect, 5–7 mm long, ovate, acuminate, chartaceous or cartilaginous, apical margin like rest of bract, same as body of bract, awn less than half as long as the bract body. Female flower 5.5–6 mm long, with a fleshy pedicel. Female tepals membranous, glabrous and smooth, smaller than nut and not obscuring the nut surface, midrib flush with the tepal body, apices obtuse or acute, inner and outer whorls the same length. Female outer lateral tepals like other tepals, 1–1.5 mm long. Female odd outer tepal oblong or ovate, 1–1.5 mm long. Female inner tepals oblong or ovate, 1–1.5 mm long. Staminodes absent. Styles plumose, white, 2. Style bases fused to form a pillar. Ovary with 1 locule, indehiscent. Fruit: indehiscent fruits with a hard woody ovary wall. Perianth presence on fruits persistent, membranous, shorter than nut. Nut cap smooth, wall smooth or wall pitted, 4–5 mm long, 2.8–3.3 mm diam., shape in side view obovate, shape in top view round in cross section, brown. Elaiosome present, 1–1.5 mm long, less than half as long as nut.
