    Habit
    Caespitose perennial with short oblique rhizome; culms up to 100 cm tall, erect, unbranched; basal leaf sheaths broadly expanded, flabellate, chartaceous and pallid or indurated, yellow and glossy, glabrous to densely pubescent, somewhat compressed, long-persistent and forming a swollen base to the culm; leaf laminas 6–22 cm × 3–10 mm, flat or folded, rarely loosely involute, glabrous to scaberulous or pilose on the surface, pectinate-ciliate on the margins with tubercle-based setae, acute at the apex.
    Inflorescences
    Panicle 10–20 cm long, pyramidal to ovate; branches in a succession of whorls, these progressively shorter upwards, glabrous, with inconspicuous long linear glands, the spikelets usually in pairs on the branchlets, these confined to the distal 1/2–2/3 of the primary branches.
    Spikelets
    Spikelets 2.5–4.5 mm long, dark green; inferior glume 1/2–3/4(4/5) the length of the spikelet, rarely less but variable even in the same panicle, narrowly lanceolate to lanceolate, nerveless or occasionally 1-nerved, glabrous, acute to acuminate at the apex; superior glume as long as the spikelet, lanceolate-elliptic, 1-nerved, glabrous, acute at the apex; lemma almost as long as the spikelet, lanceolate-elliptic; anthers 3, 1.3–2.6 mm long.
    Fruits
    Grain 1.5–2(2.4) mm long, elliptic, lightly laterally compressed.

    Inflorescences
    Inflorescence a panicle. Panicle open; pyramidal; 10-20 cm long; contracted about primary branches. Primary panicle branches whorled at most nodes (7-9 whorls); naked below. Panicle branches glabrous in axils. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 3-4.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 3-4.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes deciduous; similar; exceeding apex of florets. Lower glume oblong; 1.7-4 mm long; 0.5-0.75 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute to acuminate. Upper glume oblong; 3-4.5 mm long; 1.1 length of adjacent fertile lemma; membranous; dark green; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.
    Florets
    Fertile lemma lanceolate; 2.4-4 mm long; membranous; dark green; without keel; 1 -veined. Lemma apex acute. Palea 2 -veined. Palea keels approximate.
    Flowers
    Anthers 3; 1.6-1.7 mm long.
    Fruits
    Caryopsis with free soft pericarp; ellipsoid; 1.3-2 mm long.
