Vegetative parts: plants tufted, 0.5–1 m tall, basal diameter 0.1–0.2 m, crown diameter 0.3–0.5 m, compact, without spreading rhizomes or stolons. Fertile culms unbranched, finely rugulose (culms as they dry form longitudinal furrows), olivaceous, 0.6–1 m tall, diameter at base 0.8–1.7 mm, diameter at apex 0.4–1 mm. Clusters of sterile branches at the nodes of the fertile branches absent. Sheaths closely convoluted, 25–60 mm long, green at base, brown becoming paler towards apex, apical margins broadly chartaceous and soon decaying, hyaline shoulders absent, apex, excluding the membranous lobes, acute. Sheath-mucro penicellate, straight and erect, 0–2 mm long. Males: male inflorescence with 6–10 spikelets or 11–20 spikelets, paniculate, 30–100 mm long, 20–40 mm wide. Male inflorescence spathes persistent, upper margins lacerated and largely decayed at anthesis, shorter than spikelets, chartaceous. Male flowers in spikelets. Male spikelets pendulous on flexible pedicels, oblong, apex rounded, 5–15 mm, 4–5 mm, with 18–32 flowers, pedicels shorter than the spikelets or as long as the spikelets or longer than the spikelets, flattened. Male bracts as tall as flowers or taller than flowers, 3.5–4.5 mm long, oblong, acute, chartaceous, bract upper margin like body of bract, bract awn minute or absent. Male flower 2.8–4 mm long. Male tepals sepals more rigid than petals, chartaceous, petals membranous, oblong, inner and outer tepals the same length. Male outer lateral tepals keeled or winged or conduplicate, glabrous. Anthers 1.5–2.3 mm long, included in the flowers. Pistillode absent. Females: female inflorescence linear or paniculate or racemose, 25–110 mm long, 10–40 mm wide, with 2–5 spikelets or 6–10 spikelets. Female spathes longer than the spikelets, not obscuring spikelet, persistent, chartaceous. Female spikelet pedicel simple or pedicel sparsely branching, oblong, apex rounded, 10–30 mm long, with 10–42 flowers, with 0 sterile bracts. Female bracts at least twice as long as flowers, 5–10 mm long, oblong (triangular), acute, chartaceous, apical margin like rest of bract, same as body of bract, awn minute or absent. Female flower 2.1–3.5 mm long, without a fleshy pedicel. Female tepals cartilaginous, glabrous and smooth, at least as tall as nut, wrapped around it and obscuring the surface, midrib flush with the tepal body, apices rounded, inner whorl shorter than outer. Female outer lateral tepals keeled or winged, wings entire, wider than body, 2–3.5 mm long. Female odd outer tepal oblong, 1.5–2.5 mm long. Female inner tepals oblong, 1.5–2.5 mm long. Staminodes absent. Styles plumose, white, 1. Ovary with 1 locule, indehiscent. Fruit: indehiscent fruits with a softer ovary wall. Perianth presence on fruits persistent, winged. Shape of winged dispersal unit orbicular or oblong, narrower than long (more rarely, and then pretty marginal). Nut apex smooth, without a distinct cap, wall smooth, 1.4–2.1 mm long, 0.8–1.3 mm diam., shape in side view elliptical, shape in top view elliptical in cross section (with lateral ridges), brown (quite dull, with obscurely papillose surface). Elaiosome absent.
