Vegetative parts: plants tufted, 0.3–0.7 m tall, basal diameter 0.01–0.2 m, crown diameter 0.1–1 m, compact, without spreading rhizomes or stolons or with rhizomes. Rhizome very short with culms aggregated at base, 8–10 mm in diam., culms 1–4 mm apart. Fertile culms unbranched, smooth, olivaceous or speckled golden, 0.3–0.7 m tall, diameter at base 0.4–1 mm, diameter at apex 0.3–1 mm. Sheaths persistent, with no abscission line, closely convoluted or loosely convoluted, 10–25 mm long, brown with yellowish apex and margins, apical margins narrowly membranous, hyaline shoulders absent or small, rounded ('hyaline shoulders' possibly a continuation of memranous margin - very narrow, but present), hyaline shoulder 0.01 of sheath body length, apex, excluding the membranous lobes, acute or obtuse. Sheath-mucro absent or penicellate, straight and erect, 1–4 mm long, closely convolute, or loose in there upper portions. Males: male inflorescence with 2–5 spikelets or 6–10 spikelets, racemose or paniculate, 20–90 mm long, 8–12 mm wide. Male inflorescence spathes persistent, as tall as spikelets or taller than spikelets, chartaceous or cartilaginous, erect-spreading, expanded. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, ovate or orbicular, apex obtuse or acute, 6–9 mm, 4–7 mm, with 15–25 flowers, pedicels absent ie spikelets sessile or shorter than the spikelets, terete or angular. Male bracts shorter than flowers, 4–6 mm long, ovate, acuminate, cartilaginous, bract upper margin like body of bract, bract awn between half and as long as the bract body, appearance similar to those of Hypodiscus albo-aristatus, with the awn paler than the body. Male flower 4–5 mm long. Male tepals sepals and petals the same rigidity, chartaceous, oblong, inner and outer tepals the same length. Male outer lateral tepals conduplicate or keeled or winged, glabrous. Anthers 1–2 mm long, exserted from the flowers. Pistillode absent. Females: female inflorescence linear or paniculate or racemose, 12–80 mm long, 3–7 mm wide, with 2–5 spikelets or 6–10 spikelets. Female spathes as long as the spikelets or longer than the spikelets, not obscuring spikelet, persistent, cartilaginous. Female spikelet sessile or pedicel simple, elliptical or obovate, apex rounded or obtuse or acute, 8–12 mm long, with 1 flowers, with 10–15 sterile bracts. Female bracts taller than flowers, erect, 6–12 mm long, oblong, acuminate, cartilaginous, apical margin like rest of bract, paler than body of bract, awn less than half as long as the bract body. Female flower 5–6.5 mm long, without a fleshy pedicel. Female tepals membranous, glabrous and smooth, smaller than nut and not obscuring the nut surface, midrib raised, apices acute, inner whorl shorter than outer. Female outer lateral tepals like other tepals, 1–2 mm long. Female odd outer tepal ovate, 1–2 mm long. Female inner tepals ovate, 0.5–1 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 with several rows of ridges, wall smooth or wall tuberculate, (3.67–)4.69(–5.5) mm long, (2.33–)2.69(–3.17) mm diam., shape in side view elliptical, shape in top view round in cross section, brown. Elaiosome absent.
