Vegetative parts: plants several much-Branched culms from base (long culms from the base, the apical half very divaricate, but these culms soon flop over, thus forming the tangled growth), 0.3–1 m tall, with stolons (probably, not well enough investigated). Fertile culms branching or much branched, roughly warty, olivaceous, 0.1–1 m tall, diameter at base 1.8–3.2 mm, diameter at apex 0.3–0.7 mm. Sheaths closely convoluted, 7–25 mm long, brown, apical margins narrowly membranous, hyaline shoulders tall, acute, hyaline shoulder 0.2–0.5 of sheath body length, apex, excluding the membranous lobes, acute or obtuse. Sheath-mucro penicellate or clavate, straight and erect, 1–5 mm long. Males: male inflorescence with 1 spikelet. Male inflorescence spathes persistent, like the floral bracts, chartaceous. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong, apex rounded, 10–30 mm, 5.5–7.5 mm, with 5–15 flowers, pedicels absent ie spikelets sessile. Male bracts taller than flowers, 10–15 mm long, oblong, acute, chartaceous, bract upper margin like body of bract or membranous, thinner texture than the body (not sharply distinct from the body of the bract), bract awn minute or absent. Male flower 3.7–4.8 mm long. Male tepals sepals more rigid than petals, cartilaginous, petals membranous, linear or oblong, inner tepals shorter than outer tepals. Male outer lateral tepals conduplicate, keel densely villous. Anthers 1.2–2.3 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence with 1 spikelet. Female spathes shorter than the spikelets, persistent, chartaceous. Female spikelet sessile, oblong, apex rounded or obtuse, 10–20 mm long, with 2–16 flowers, with 0 sterile bracts. Female bracts taller than flowers or at least twice as long as flowers, 8–20 mm long, oblong, truncate or obtuse, chartaceous, apical margin like rest of bract or membranous (then grading gradually from chartaceous to membranous), paler than body of bract or same as body of bract, awn minute or absent. Female flower 4.5–6 mm long, without a fleshy pedicel. Female tepals cartilaginous, keels of lateral sepals sparsely villous or keels of lateral sepals densely villous, midrib flush with the tepal body, apices acute, inner and outer whorls the same length or inner whorl shorter than outer. Female outer lateral tepals conduplicate, 4.5–6 mm long. Female odd outer tepal oblong, 4.5–5.5 mm long. Female inner tepals ovate, 4–5.5 mm long. Staminodes present. Styles 3. Style bases free. Ovary with 2 locules, dehiscent. Fruit: seed 1.2–2 mm long, (0.8–)0.96(–1.12) mm in diameter, shape in side view elliptical, shape in diameter triangular in cross section, brown, smooth.
