Loosely tufted annual 250-1000 mm high; culm erect or geniculately ascending, rooting at nodes; nodes sparsely to densely hairy. Leaf blade 45-300 x 5-35 mm, lanceolate, plicate at first, later expanded and mostly flat, sparsely hairy. Inflorescence open, branches raceme-like, stiff, spreading or suberect, sometimes terminated by a bristle; bristles solitary, up to 13 mm long, scabrid, green, flushed purple. Spikelet 2.3-2.8 mm long, upper glume and lower lemma obtuse or subacute; lower glume 3-nerved; upper lemma rugose; anther 0.8-1.0 mm long.
Annual, loosely tufted (culms erect or geniculately ascending and rooting at nodes), up to 1 m high. Leaf blades 45-300 mm long, 5-35 mm wide, lanceolate, plicate at first. Culm nodes pubescent. Spikelets 2.3-2.8 mm long. Panicle open with stiff, spreading or suberect branches; bristles solitary; lower glume 3-nerved.
Panicle 4–20 cm. long, narrowly pyramidal, the spikelets subsessile in 2 rows on raceme-like primary branches, these villous or sometimes merely pubescent; bristles 5–10 mm. long.
Inferior glume obtuse, 1/8–1/4 length of spikelet, superior glume 4/5 to as long as spikelet.
Spikelets 2–2.5 mm. long, narrowly elliptic, slightly dorsally compressed.
Leaf laminae lanceolate, plicate, thin, flaccid, light green.
Culms 25–100 cm. high.
Superior lemma rugose.
