Annual; culms erect or decumbent at the base, rather freely branching from nearly all the nodes, the nodes bearded; sheaths rather loose, keeled toward the summit, glabrous or sparsely papillose-pilose near the summit; ligule 2-3 mm. long; blades mostly 10-15 cm. long, 6-12 mm. wide, acuminate, narrowed toward the base, sometimes petiole-like, the margins very scabrous; racemes in pairs, ap-pressed together and appearing as if one when young, 3-10 cm. long, terminal on the main culm and branches, long-exserted from the upper bladeless sheath, the rachis thick, readily disarticulating, ciliate on the outer edges; spikelets 3-4 mm. long, obtuse, the summit membranaceous, otherwise indurate with 3-5 strong transverse ridges; awns 1.5 cm. long, tightly twisted below, loosely twisted above the bend.
Straggling annual; culms 10–100 cm. high.. Leaf-blades 5–30 cm. long, 3–15 mm. wide.. Inflorescences terminal and axillary, of paired racemes, each 3–12 cm. long; internodes and pedicels clavate, ciliate.. Sessile spikelet oblong-ovate, 4–6 mm. long; lower glume coriaceous and transversely rugose below, membranous above, 2-keeled along its length; upper lemma with an awn 15–20 mm. long.. Pedicelled spikelet resembling the sessile and on a pedicel 1/3 the length of the internode, or much reduced and on a pedicel equalling the internode.
An annual grass. It can last longer. It is a straggling plant and grows 10-100 cm high. The leaf blades are 5-30 cm long by 3-15 mm wide. They are slightly hairy. The seed grains are oblong.
