Annual 100-1 200 mm high, culms erect or geniculate. Leaf blade 30-300 x 2-10 mm. Inflorescence with several to many spike-like, ascending, one-sided racemes, not adpressed to main axis; rachis puberulous, occasionally pilose; spikelets paired. Spikelet (2.5-)3.0-5.0 mm long, sparsely pubescent; lower glume absent; upper glume with a short awn 0.5-4.0 mm long; lower floret sterile, palea absent; upper lemma awn 0.3-1.0 mm long; anther 0.5-1.0 mm long.
Annual; up to 1.2 m high. Culms erect or geniculate. Leaf blades 30-300 x 2-10 mm. Flowers: panicle open; branches several to many; ascending; spikelets (2.5-)3.0-5.0 mm long; lower glume apparently absent; upper glume with a short awn; lower floret sterile; palea absent.
An annual grass. It grows 10-120 cm high. It can be erect or bent upwards. The leaf blades are 3-30 cm long and 2-10 mm wide. The flower panicle is 3-20 cm long. The stalk can be 3 sided and hairy. The spikes are in pairs. The spikelets are sword shape and 3-5 mm long.
Inflorescence of 3–20 racemes, these 1–5 cm. long, bearing paired spikelets on a puberulous (occasionally pilose) triquetrous or narrowly winged rhachis; pedicels commonly setose, those of a pair usually free.
Inferior glume absent; superior glume attenuate to an awnlet 0.5–4 mm. long.
Spikelets (2.5)3–5 mm. long, lanceolate, thinly pubescent.
Culms 10–120 cm. high, erect or geniculately ascending.
Inferior floret represented only by a lemma.
Superior lemma with a mucro 0.3–1 mm. long.
Annual.
