Delicate annual; culms 5–60 cm. long, slender, up to 2 mm. diameter, creeping or scrambling, the leaf-sheaths mostly shorter than the internodes.. Leaf-blades 1–6 cm. long, 1–7 mm. wide, obtuse.. Racemes 1–2.5 cm. long, fragile, inconspicuous; internodes and pedicels linear to narrowly clavate, glabrous or sometimes ± hairy; spatheoles convolute.. Sessile spikelet narrowly lanceolate, 2–4 mm. long; lower glume subcoriaceous, obscurely nerved, keeled above but merely inflexed below, glabrous or occasionally pilose; upper lemma bifid almost to the base; awn 7–12 mm. long, its column scarcely exserted from the spikelet, sometimes awnless; anthers 0.5–1 mm.. Pedicelled spikelet small, up to 1.5 mm. long, with an awn up to 6 mm. long.
Delicate, scrambling, sometimes erect annual 50-600 mm high. Leaf blade to 70 x 2-5 mm, lower blade apex obtuse; ligule undivided. Inflorescence exserted from spatheole at maturity; raceme glabrous or sometimes hairy throughout; internode and pedicel filiform, linear to narrowly clavate. Sessile spikelet 2.5-3.0 mm long, dorsally compressed; lower glume glabrous, occasionally hairy; upper lemma bifid for almost whole length, awn 7-12 mm long; anther 0.5-0.7 mm long. Pedicellate spikelet reduced to a glume; awn straight, up to 6 mm long.
Racemes borne throughout the plant, 0.5–3 cm long, filiform, glabrous or sometimes with short hairs throughout, shortly exserted from and partially enclosed by the linear spatheole; peduncle shorter than the raceme; internodes and pedicels filiform and flattened below, clavate above.
Sessile spikelet 2.3–3.5 mm long, 1/5 as long again as the pedicel, linear-ovate, dorsally compressed, rounded at the base; inferior glume slightly convex; superior lemma bifid almost to the base; awn slender, 6–13 mm long, geniculate; anthers very small, 0.5–0.6 mm long.
Delicate annual, up to 0.6 m high. Leaf blades up to 70 mm long, 2-5 mm wide, lower leaves with rounded blade tips. Spikelets (sessile) 2.5-3.0 mm long (pedicellate reduced to a glume). Inflorescence exserted from spathe.
Delicate, caespitose, erect or ± scrambling and decumbent annual, tinged with bright purplish-red; culms up to 40(80) cm high, much branched from below, often in fascicles; internodes delicate, linear, compressed.
Leaf sheaths shorter than the internodes, glabrous; laminas 0.8–5 cm × up to 5.5 mm, keeled, obtuse at the apex.
Pedicelled spikelet reduced to an awned vestigial glume 0.3–1.2 mm long; awn 2.5–3.5 mm long, straight.
