Panicle ovate, 7–25 cm. long, open, the axis glabrous or pilose, much branched, the spikelets borne on long slender pedicels.. Spikelets 6–30-flowered, ovate to ovate-oblong, 3–7mm. long and 2.5–3 mm. wide, yellowish green tinged with purple, the rhachilla ± covered by the base of the closely imbricate lemmas, breaking up from the base, the rhachilla persistent; glumes subequal, narrowly to broadly ovate, 1.5–2 mm. long, acute; lemmas broadly ovate-elliptic, 1.5–2 mm. long, gibbous on the back, the tip abruptly cuspidate to an acute apex or sometimes obtusely triangular; palea falling soon after the lemma, the keels ciliolate with hairs 0.1–0.2 mm. long; anthers 3, 0.2–0.3 mm. long.. Caryopsis ellipsoid, 0.7 mm. long.
Loosely caespitose annual; culms up to 90 cm tall, erect or ascending, somewhat stout, branched or unbranched, glabrous at the nodes, eglandular; leaf sheaths glabrous, the lowermost compressed and keeled; ligule a line of hairs; leaf laminas 5–20 cm × 2–4 mm, linear, flat or folded, glabrous, eglandular.
Panicle 7–25 cm long, ovate, open and richly branched, the spikelets evenly distributed on long fine pedicels 5–25 mm long, the primary branches not in whorls, terminating in a fertile spikelet, glabrous or thinly pilose in the axils, eglandular.
Caryopsis 0.7–0.8 mm long, elliptic.
