Vegetative parts: plants clumped, 0.4–1 m tall, basal diameter 1–3 m, crown diameter 1–3 m, with rhizomes. Rhizome spreading, unbranched or sparsely branched, culms evenly spaced, 4–9 mm in diam., culms 4–15 mm apart. Fertile culms unbranched, round (not compressed), solid or with a small central cavity, smooth or finely rugulose, green or olivaceous, 0.3–1 m tall, diameter at base 2–5 mm, diameter at apex 1.5–3 mm. Clusters of sterile branches at the nodes of the fertile branches absent. Sheaths dropping off, with an abscission line present, loosely convoluted, 25–60 mm long, margins entire, tan with reddish-brown speckles, margins 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, the mucro is only visible as a tiny extension of the midrib and, in contrast to Elegia persistens, it is generally the same colour as the sheath (not darker). Males: male inflorescence with 50–100 spikelets or 101–500 spikelets, paniculate, 50–120 mm long, 10–20 mm wide. Male inflorescence spathes persistent or caducous (spathes usually persistent), taller than spikelets, cartilaginous, often brownish with a distinctive golden margin. Male spathellae inconspicuous or absent or conspicuous (some are conspicuous, though the majority is small and inconspicuous), 6–15 mm long. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, ovate or undifferentiated, apex undifferentiated, 3–5 mm, 1.5–3 mm, with 1–5 flowers, pedicels shorter than the spikelets or as long as the spikelets, terete or angular. Male bracts shorter than flowers, 0.5–0.8 mm long, orbicular, acute, chartaceous, bract upper margin like body of bract, bract awn minute or absent, very small, rather elongated. Male flower 2–3.5 mm long. Male tepals sepals and petals the same rigidity, cartilaginous, oblong, inner tepals longer than outer tepals. Male outer lateral tepals keeled or winged or as other tepals, glabrous. Anthers 1.5–2 mm long, included in the flowers. Females: female inflorescence linear or paniculate, 60–120 mm long, 10–20 mm wide, with 6–10 spikelets or 11–20 spikelets or 21–50 spikelets or 51–100 spikelets. Female spathes longer than the spikelets, obscuring spikelet, persistent, cartilaginous. Female spathellae inconspicuous or absent. Female spikelet pedicel sparsely branching, undifferentiated, 3–4 mm long, with 1–4 flowers, with 0 sterile bracts. Female bracts shorter than flowers, 0.5–1 mm long, ovate, rounded or acute, cartilaginous, apical margin membranous, paler than body of bract, awn minute or absent. Female flower 3–4 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 raised, margins entire, apices rounded or acute, inner and outer whorls the same length. Female outer lateral tepals like other tepals or conduplicate, 2.5–3.5 mm long. Female odd outer tepal oblong, 2.5–3.5 mm long. Female inner tepals oblong, 2.7–3.7 mm long. Staminodes present. Styles plumose, white or pink or red, 3 or 2. Style bases seated on a stylopodium. Ovary with 1 locule, indehiscent. Fruit: indehiscent fruits with a softer ovary wall. Nut apex smooth, without a distinct cap, wall smooth, (1.4–)3.09(–3.52) mm long, (1.2–)1.37(–1.56) mm diam., shape in side view ovate, shape in top view elliptical in cross section or triangular in cross section, brown. Elaiosome absent.
