Annual; culms 20–60 cm. high, erect.. Leaf-blades flat, 3–9 cm. long and 2–4 mm. wide.. Panicle linear, 3–17 cm. long, the spikelets sessile on stubby side-branches 5–10 mm. long.. Spikelets 2–20-flowered, broadly ovate to oblong, 2–9 mm. long and 2–4 mm. wide, laterally compressed, densely imbricate, yellowish green tinged with purple, breaking up from the apex, the rhachilla fragile; glumes ovate, 1.5–2 mm. long; lemmas rotund to oblate, 2 mm. long, cartilaginous; palea subrotund, the keels winged and scaberulous; anthers 3, 0.5–0.6 mm. long.. Caryopsis ellipsoid, 0.5 mm. long, with a pronounced reticulate pattern.
Caespitose annual; culms up to 60 cm tall, erect, branched below, glabrous at the nodes, eglandular; leaf sheaths eglandular; ligule a line of hairs; leaf laminas 3–9 cm × 2–4 mm, linear, flat, pilose with tubercle-based hairs, eglandular.
Panicle 3–17 cm long, linear to lanceolate, the spikelets sessile on short stubby branches up to (rarely exceeding) 1 cm long, the primary branches not in whorls, terminating in a fertile spikelet, glabrous in the axils, eglandular.
