Vegetative parts: plants tufted, 0.5–1 m tall, basal diameter 0.05–0.15 m, crown diameter 0.3–0.9 m, compact, without spreading rhizomes or stolons or with rhizomes. Rhizome very short with culms aggregated at base or looping up, with clusters of culms on the uploops, 3–4 mm in diam., culms 1–5 mm apart. Fertile culms unbranched, smooth, olivaceous, 0.5–1 m tall, diameter at base 1.7–2.2 mm, diameter at apex 0.7–1.1 mm. Sheaths closely convoluted, 40–70 mm long, reddish-brown, apical margins broadly chartaceous and soon decaying, hyaline shoulders absent, apex, excluding the membranous lobes, acuminate. Sheath-mucro awl- or needleshaped, straight and erect, 0–5 mm long. Sterile branch leaf-sheath 3–7 mm long, hyaline shoulder 5–7 mm long, leaf-blade 7–10 mm long; leaf blade 0.5 mm wide. Reproductive system with both male and female. Males: male inflorescence with 11–20 spikelets, paniculate, 50–70 mm long, 30–50 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 or elliptical, apex rounded, 10–16 mm, 4–6 mm, with 20–30 flowers, pedicels as long as the spikelets or longer than the spikelets, flattened. Male bracts taller than flowers, 5–10 mm long, oblong or ovate, acute, hyaline (margins 1/3 of width) or chartaceous (central 2/3), bract upper margin like body of bract, bract awn minute or absent, brown central region, membranous margins. Male flower 4–4.5 mm long. Male tepals sepals and petals the same rigidity, chartaceous, linear or oblong, inner and outer tepals the same length. Male outer lateral tepals conduplicate, glabrous. Anthers 1.5–1.8 mm long, included in the flowers. Females: female inflorescence racemose, 25–60 mm long, 10–20 mm wide, with 1 spikelet or 2–5 spikelets. Female spathes shorter than the spikelets or as long as the spikelets, persistent, chartaceous. Female spikelet sessile or pedicel simple, oblong or obtriangular, apex truncate or rounded, 20–35 mm long, with 15–25 flowers, with 0 sterile bracts. Female bracts at least twice as long as flowers, 13–28 mm long, oblong or ovate, acute, chartaceous, apical margin like rest of bract, same as body of bract, awn minute or absent. Female flower 4.5–7 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 acute, inner whorl shorter than outer. Female outer lateral tepals keeled or winged, wings entire, wings lateral sepals decurrent, without grooves, wider than body, exserted past bracts, 4.5–6.5 mm long. Female odd outer tepal oblong, 4–6 mm long. Female inner tepals oblong, 3–4 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 oblong, narrower than long. Nut apex smooth, without a distinct cap, wall smooth, 3 mm long, 1.7 mm diam., shape in side view oblong, shape in top view elliptical in cross section, black. Elaiosome absent.
