Vegetative parts: plants tufted, 0.2-0.6 m tall, basal diameter 0.01-0.05 m, crown diameter 0.1-0.3 m, compact, without spreading rhizomes or stolons. Fertile culms branching, finely rugulose or finely warty or roughly warty, olivaceous, 0.2-0.6 m tall, diameter at base 0.3-1 mm, diameter at apex 0.2-0.5 mm. Sheaths closely convoluted, 7-15 mm long, reddish brown, apical margins coriaceous, like the rest of the body or narrowly membranous, hyaline shoulders tall, acute, hyaline shoulder 0.5-1 of sheath body length, apex, excluding the membranous lobes, obtuse or truncate. Sheath-mucro penicellate, straight and erect, 2-4 mm long, very abruptly different membranous lobes, often taller than the awn; one specimen has the lobes fused to the awn, and the apex of the sheath acute. Males: male inflorescence with 6-10 spikelets or 11-20 spikelets or 21-50 spikelets, paniculate (often looking distichous), 20-60 mm long, 5-25 mm wide. Male inflorescence spathes persistent, like the floral bracts, coriaceous, with broad membranous apical lobes, about half the length of the spikelet. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, obtriangular, apex truncate, 9-15 mm, 5-8 mm, with 3 flowers, pedicels absent ie spikelets sessile or shorter than the spikelets, terete or angular. Male bracts taller than flowers, 4.5-8 mm long, oblong, acute, cartilaginous, bract upper margin membranous, thinner texture than the body (upper third), bract awn minute or absent, body rugose, membranous apex often reddish towards the tips. Male flower 3.5-4.5 mm long. Male tepals sepals more rigid than petals, chartaceous, petals membranous, oblong, inner and outer tepals the same length. Male outer lateral tepals conduplicate, glabrous. Anthers 2-2.5 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence paniculate (But remarkably distichous), 20-80 mm long, 10-35 mm wide, with 2-5 spikelets or 6-10 spikelets. Female spathes like floral bracts or shorter than the spikelets, persistent, coriaceous. Female spikelet sessile or pedicel simple, obtriangular, apex truncate, 6-10 mm long, with 2-3 flowers, with 0-1 sterile bracts. Female bracts taller than flowers, 5.5-8 mm long, oblong, acute, cartilaginous, apical margin membranous (lower bracts with wide membranous margin, upper bracts with a much narrower membranous margin), paler than body of bract, awn minute or absent. Female flower 3-3.5 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 and outer whorls the same length. Female outer lateral tepals keeled or winged, wings entire, wider than body, exserted past bracts, 3-3.5 mm long. Female odd outer tepal oblong, 2.8-3.5 mm long. Female inner tepals oblong, 2.5-3 mm long. Staminodes absent. Styles feathery, white, 3. Style bases seated on a stylopodium. 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. Nut apex smooth, without a distinct cap, wall smooth, 2-2.1 mm long, 0.7 mm diam., shape in side view elliptical, shape in top view round in cross section (with three ribs), brown. Elaiosome absent.
