Vegetative parts: plants tufted, 0.15-0.5 m tall, basal diameter 0.01-0.03 m, crown diameter 0.1-0.3 m, compact, without spreading rhizomes or stolons. Fertile culms branching, finely rugulose or finely warty, olivaceous, 0.15-0.5 m tall, diameter at base 0.1-0.4 mm, diameter at apex 0.1-0.3 mm. Sheaths closely convoluted, 4-12 mm long, green, eventually turning brown, apical margins narrowly membranous or broadly membranous, hyaline shoulders absent or small, rounded or tall, acute, apex, excluding the membranous lobes, acute or obtuse. Sheath-mucro penicellate, straight and erect, 0.5-3 mm long. Males: male inflorescence with 1 spikelet. Male inflorescence spathes caducous. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong, apex rounded, 10-20 mm, 3-7 mm, with 4-7 flowers, pedicels absent ie spikelets sessile. Male bracts more than twice as tall as flowers, 5.5-6.5 mm long, oblong, acute, lax, cartilaginous (lower half) or membranous (upper half), bract upper margin membranous, thinner texture than the body (upper half), bract awn minute or absent, very distinctive by the membranous upper half. Male flower 2.5-3 mm long. Male tepals sepals more rigid than petals, cartilaginous, petals membranous, linear or oblong, inner and outer tepals the same length. Male outer lateral tepals as other tepals, glabrous. Anthers 1.4-1.6 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence with 1 spikelet. Female spathes like floral bracts, persistent, cartilaginous. Female spikelet sessile, linear or oblong, apex rounded, 5-10 mm long, with 3-8 flowers, with 0 sterile bracts. Female bracts taller than flowers or at least twice as long as flowers, 2-4.5 mm long, oblong or ovate, acute, cartilaginous (lower half) or membranous (upper half), apical margin membranous (upper half), paler than body of bract, lax, exposing spikelet axis, awn minute or absent. Female flower 1.2-1.5 mm long, curved, without a fleshy pedicel. Female tepals chartaceous or cartilaginous, scabrid all over or keels of lateral sepals sparsely villous, 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 conduplicate, 1.2-1.5 mm long. Female odd outer tepal oblong, 1.2-1.5 mm long. Female inner tepals oblong, 1.2-1.5 mm long. Staminodes present. Styles feathery, 3. 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, (1.16-)1.36(-1.6) mm long, (0.32-)0.45(-0.6) mm diam., shape in side view elliptical, shape in top view triangular in cross section, tan. Elaiosome absent.
