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.
Perennial 380-920 mm high; rhizome short, oblique. Leaf blade 60-220 x 3-10 mm, margins pectinate-ciliate with tubercle-based setae. Inflorescence 100-200 mm long, branches whorled, whorls fewer than 10; spikelets loosely clustered on upper 2/3 of the branches. Spikelet 3.0-4.5 mm long; glumes unequal; lower glume 4.0 mm long, 1/2-3/4 as long as spikelet, apex acute to acuminate; upper glume longer than spikelet, apex acute; lemma lanceolate-elliptic; anther 1.5-2.5 mm long.
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.
Perennial, rhizomatous, up to 0.92 m high. Leaf blades 60-220 mm long, 3-10 mm wide, ciliate on margins. Spikelets 3.0-4.5 mm long. Panicle 100-200 mm long, whorled, with fewer than 10 whorls; spikelets loosely clustered on upper two-thirds of branches; lower glume 1.7-4.0 mm long, half to three-quarters the spikelet length; upper glume longer than spikelet.
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.
Grain 1.5–2(2.4) mm long, elliptic, lightly laterally compressed.
