Tufted annual to 700 mm high; culm eglandular. Leaf blade 90-300 x 1.5-8 mm. Inflorescence delicate, open, much branched; lowest branches usually whorled, axils glabrous; pedicels long, slender. Spikelet 1.5-2.5 x 0.5-1.2 mm, narrowly elliptic when young to broadly ovate when mature, florets 1-2(-3); rachilla persistent, becoming fragile in upper part, lemmas and/or paleas breaking up from base upwards; glumes subequal; lemma 1.0-1.5 mm long, keeled, lateral nerves not prominent, usually faint but visible near base; palea persistent, keels wingless, glabrous to scabrid; anthers 3, 0.2-0.3 mm long; caryopsis obovate.
Annual; up to 0.7 m high; tufted. Leaf blades up to 300 x 8 mm. Flowers: panicle open; delicate; much branched; with branches spreading away from main axis; pedicels long and slender; spikelets 1.5-2.5 x 0.5-1.2 mm; distant; spikelets narrowly elliptic when young to broadly ovate when mature; with 1 or 2(3) florets; rachilla persistent; becoming fragile in upper part; lemmas and/or paleae breaking up from base upwards; lemmas 1.0-1.5 mm long; palea keels glabrous to scabrid; anthers 3; 0.2-0.3 mm long.
Annual, tufted, up to 0.7 m high. Leaf blades up to 300 mm long, up to 8 mm wide. Spikelets 1.5-2.5 mm long, 0.5-1.2 mm wide. Inflorescence open, delicate, much-branched, pedicels long and slender; spikelets narrowly elliptic when young to broadly ovate when mature, with 1-2(-3) florets, rhachilla persistent, becoming fragile in upper part, lemmas and/or paleas breaking up from base upwards; lemma 1.0-1.5 mm long; palea keels glabrous to scabrid; anthers 3.0,2-0.3 mm long.
Panicle 16–30 cm long, narrowly ovate-elliptic, delicate and open, the spikelets evenly distributed on slender pedicels 1.5–5 mm long, the primary branches (or at least the lowermost) in whorls, terminating in a fertile spikelet, glabrous in the axils, eglandular.
Caespitose annual; culms up to 80 cm tall, erect, unbranched, glabrous at the nodes, eglandular; leaf sheaths glabrous or thinly pilose below; ligule a line of hairs; leaf laminas 9–30 cm × 1.5–5(8) mm, linear, flat or involute, glabrous, eglandular.
Caryopsis 0.6–0.7 mm long, obovate.
