Vegetative parts: plants tufted, 0.8–2 m tall, basal diameter 0.5–0.8 m, crown diameter 0.5–1 m, compact, without spreading rhizomes or stolons. Fertile culms unbranched, round (not compressed), solid or with a small central cavity, smooth or finely rugulose, olivaceous, 0.8–2 m tall, diameter at base 2–3 mm, diameter at apex 1–2 mm. Clusters of sterile branches at the nodes of the fertile branches absent. Sheaths more than 1 per culm, dropping off, with an abscission line present, loosely convoluted, 30–50 mm long, margins entire, tan with reddish-brown speckles,margin also tan, upper 1/3 in colour and texture similar to the lower 2/3, apical margins narrowly membranous, hyaline shoulders absent, apex, excluding the membranous lobes, acute. Sheath-mucro penicellate, straight and erect, 0.1–0.5 mm long. Males: male inflorescence with 21–50 spikelets or 50–100 spikelets or 101–500 spikelets, paniculate, 50–110 mm long, 10–20 mm wide. Male inflorescence spathes persistent or caducous, taller than spikelets, cartilaginous. Male spathellae inconspicuous or absent. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, undifferentiated, apex undifferentiated, 4–5 mm, 2–3 mm, with 1–4 flowers, pedicels shorter than the spikelets, terete or angular. Male bracts shorter than flowers, 0.1–0.4 mm long, oblong, acute, chartaceous, bract upper margin like body of bract or membranous, thinner texture than the body, bract awn minute or absent, these are minute. Male flower 2.5–4 mm long. Male tepals sepals and petals the same rigidity, cartilaginous, oblong or ovate or obovate (inner tepals oblong, outer tepals lanceolate), inner tepals longer than outer tepals. Male outer lateral tepals keeled or winged or as other tepals, glabrous. Anthers 1–1.8 mm long, included in the flowers. Females: female inflorescence linear, 30–110 mm long, 5–10 mm wide, with 6–10 spikelets or 11–20 spikelets or 21–50 spikelets. Female spathes longer than the spikelets, obscuring spikelet, persistent, cartilaginous. Female spathellae inconspicuous or absent. Female spikelet pedicel sparsely branching, undifferentiated, apex undifferentiated, 3–4.5 mm long, with 1 flowers, with 0 sterile bracts. Female bracts shorter than flowers, erect, 0.5–1 mm long, ovate, acute, cartilaginous, apical margin like rest of bract, same as body of bract, awn minute or absent. Female flower 3–4 mm long, without a fleshy pedicel, six tepals. Female tepals cartilaginous, glabrous and smooth, at least as tall as nut, wrapped around it and obscuring the surface, midrib raised, margins entire, apices obtuse or acute, inner and outer whorls the same length. Female outer lateral tepals like other tepals or conduplicate, hidden by bracts, or bracts are shorter than flowers, 3–4 mm long. Female odd outer tepal oblong or elliptical, 3–4 mm long. Female inner tepals oblong, 3–4 mm long. Staminodes present. Styles feathery, 2. Style bases free. Ovary with 1 locule, indehiscent. Fruit: indehiscent fruits with a softer ovary wall. Perianth presence on fruits persistent, papery to leathery, not winged. Nut apex smooth, without a distinct cap, wall smooth or wall tuberculate, 3–3.8 mm long, 0.7–1.2 mm diam., shape in side view elliptical or ovate, shape in top view elliptical in cross section, brown. Elaiosome absent.
