Vegetative parts: plants tufted, 0.2–0.5 m tall, basal diameter 0.01–0.5 m, crown diameter 0.03–0.4 m, compact, without spreading rhizomes or stolons. Fertile culms unbranched, striate, olivaceous or speckled golden, 0.2–0.5 m tall, diameter at base 0.1–0.3 mm, diameter at apex 0.2–0.3 mm. Sheaths persistent, with no abscission line, closely convoluted, 10–20 mm long, olivacious to golden to grey, speckled, apical margins coriaceous, like the rest of the body, hyaline shoulders small, rounded, hyaline shoulder 0.1 of sheath body length, apex, excluding the membranous lobes, acute. Sheath-mucro penicellate, straight and erect, 3–5 mm long. Males: male inflorescence with 2–5 spikelets, racemose, 15–50 mm long, 4–10 mm wide. Male inflorescence spathes persistent, shorter than spikelets or as tall as spikelets or taller than spikelets, cartilaginous. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, elliptical, apex acute, 10–18 mm, 2–3 mm, with 8–10 flowers, pedicels absent ie spikelets sessile. Male bracts shorter than flowers or as tall as flowers, 7–9 mm long, oblong, obtuse or acute or acuminate, cartilaginous, bract upper margin like body of bract, bract awn less than half as long as the bract body, bract body red-brown, tending to black at the awn. Male flower 5–9 mm long. Male tepals sepals and petals the same rigidity, chartaceous, oblong, inner tepals longer than outer tepals. Male outer lateral tepals conduplicate, glabrous. Anthers 3–4 mm long, exserted from the flowers. Pistillode absent. Females: female inflorescence linear or racemose, 15–30 mm long, 5–8 mm wide, with 1 spikelet or 2–5 spikelets. Female spathes as long as the spikelets, persistent, cartilaginous (paler coloured than bracts, very striking). Female spikelet sessile, elliptical or obovate, apex rounded or obtuse or acute, 11–20 mm long, with 1 flowers, with 4–6 sterile bracts. Female bracts taller than flowers, erect, 11–15 mm long, oblong, acuminate, cartilaginous, apical margin like rest of bract, darker than body of bract, awn less than half as long as the bract body. Female flower 6.5–7 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 rounded or obtuse or acute, inner and outer whorls the same length or inner whorl shorter than outer. Female outer lateral tepals like other tepals, 2–2.5 mm long. Female odd outer tepal linear or oblong, 2–2.5 mm long. Female inner tepals linear or oblong, 1.5–2 mm long. Staminodes absent. Styles plumose, white, 2. 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, (4.33–)4.92(–5.5) mm long, 2.6–3 mm diam., shape in side view obovate or oblong, shape in top view round in cross section, brown. Elaiosome present, white, 2–2.5 mm long, less than half as long as nut.
