Loosely caespitose annual; culms up to 70 cm tall, erect, branched or unbranched; leaf sheaths chartaceous, usually glabrous, sometimes tuberculate-pilose especially towards the margins, terete or lightly compressed; leaf laminas 4–7.5 cm × 2.5–7 mm, flat, glabrous or tuberculate-pilose on the surface, usually pectinate on the margins with stiff tubercle-based setae but without raised glands interspersed among them, acute at the apex.
Spikelets 1.5–2.1 mm long, reddish; inferior glume 2/5–2/3 the length of the spikelet, narrowly lanceolate to lanceolate, nerveless, glabrous, acute to acuminate at the apex; superior glume as long as the spikelet, ovate-elliptic, 1-nerved, glabrous or minutely asperulous, acute to acuminate at the apex; lemma as long as the spikelet or almost so, ovate-elliptic; anthers 3, 1–1.2 mm long.
Panicle 10–18 cm long, lanceolate to narrowly oblong; branches in a succession of whorls, smooth, with elongated viscid glandular patches, the spikelets 2–3 on secondary branchlets or 5–6 directly on the primary branches, the spikelets or branchlets confined to the distal part of the primary branches.
Grain broadly elliptic to obovate, 0.7–1.25 mm long, terete or lightly laterally compressed.
