Vegetative parts: plants tufted, 0.2-0.5 m tall, basal diameter 0.01-0.05 m, crown diameter 0.1-0.3 m, compact, without spreading rhizomes or stolons (some specimens may suggest a stoloniferous habit, but it needs corroboration). Fertile culms branching, finely rugulose or finely warty, olivaceous, 0.2-0.5 m tall, diameter at base 0.8-1.5 mm, diameter at apex 0.2-0.6 mm. Sheaths loosely convoluted, 5-18 mm long, pale brown, apical margins coriaceous, like the rest of the body, hyaline shoulders absent, apex, excluding the membranous lobes, obtuse or rounded. Sheath-mucro penicellate or awl- or needleshaped, straight and erect or recurved, 2-5 mm long, distinctive spreading rounded sheaths. Males: male inflorescence with 1 spikelet or 2-5 spikelets, racemose, 12-40 mm long, 4-10 mm wide. Male inflorescence spathes persistent, like the floral bracts, cartilaginous. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong, apex rounded or acute, 5-11 mm, 3-5 mm, with 6-15 flowers, pedicels absent ie spikelets sessile. Male bracts taller than flowers, 2-5 mm long, oblong or ovate, obtuse or acute, cartilaginous, bract upper margin like body of bract, bract awn minute or absent. Male flower 2-4 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, keel sparsely villous or keel densely villous. Anthers 1.5-1.6 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence linear or paniculate or racemose, 20-90 mm long, 4-30 mm wide, with 2-5 spikelets or 6-10 spikelets or 11-20 spikelets or 21-50 spikelets. Female spathes shorter than the spikelets, persistent, coriaceous. Female spikelet sessile or pedicel simple or pedicel sparsely branching, linear or oblong, apex acute, 6-15 mm long, with 2-12 flowers, with 0-2 sterile bracts. Female bracts taller than flowers, 3-5 mm long, oblong or ovate, acuminate, cartilaginous, apical margin like rest of bract, same as body of bract, awn minute or absent. Female flower 2.2-3 mm long, without a fleshy pedicel. Female tepals chartaceous, scabrid all over or keels of lateral sepals densely 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, 2.2-3 mm long. Female odd outer tepal oblong, 1.7-2.2 mm long. Female inner tepals obovate, 1.6-2.8 mm long. Staminodes present. Styles feathery, red, 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, papery to leathery, not winged. Nut apex smooth, without a distinct cap, wall smooth, 1.8-2.5 mm long, 0.7-1 mm diam., shape in side view elliptical, shape in top view triangular in cross section, brown. Elaiosome absent.
