Tufted annual 200-600 mm high; culms branched, decumbent, rooting from lower nodes, nodes dark, glabrous. Leaf blade 27-170 x 3-10 mm. Inflorescence digitate or subdigitate, of 3-12 racemes 40-120 mm long; rachis triquetrous, broadly winged, glabrous to scaberulous; pedicel triangular, scaberulous; spikelets paired. Spikelet (1.8)2.3-3.5 mm long, acute; internode absent; lower glume a small ovate-triangular scale 0.2-0.3 mm long; upper glume shorter to nearly as long as spikelet, 3-nerved, adpressed hairy, hairs fine, acute; lower lemma equalling or just shorter than spikelet, acute, 7-nerved, scaberulous along nerves (may need a strong lens and easier to see near apex); upper lemma exposed, as long as spikelet, acute, pale yellow to pale brown; anthers 0.7-1.2 mm long.

Superior lemma as long as to somewhat shorter than the spikelet, oblong-lanceolate, slightly acuminate, pale yellow to pale brown, sometimes purplish tinged. Inferior lemma as long as the spikelet, ovate-oblong, 7-nerved, nerves scabrous, especially the subcentral and submarginal nerves, central zone often broad, appressed hairy. Superior glume 1/3–2/3 of the spikelet, ovate to oblong triangular, 3-nerved, appressed hairy, hairs fine, smooth, acute. Inferior glume short, triangular, sometimes truncate or even slightly bifid. Pedicels 2-nate, 0.3–3 mm. long, triangular, scabrous, scarcely widened at the apex. Rhachis triquetrous, broadly winged, up to 0.7 mm. wide, smooth to scaberulous with scabrous margins. Spikelets (1.8)2.1–2.8 mm. long, ovate-oblong. Culms 20–60 cm., decumbent or creeping at the base, glabrous, nodes dark and glabrous. A loosely caespitose or solitary growing annual. Ligule 1–2 mm. long, truncate, erose. Leaf sheaths smooth to scaberulous. Inflorescence composed of (2)4–8 racemes, (3)6–12 cm. long, erect, (2)3–4(5) in a inferior whorl, sometimes a second, superior whorl of 2–3 racemes. Leaf laminae 3–12 × 0.1–0.5 cm., linear, flat, scaberulous on both surfaces, with a few bulbous based bristles on the superior surface, near the base, scaberulous along the margin. Inferior lemma as long as the spikelet, ovate-oblong, 7-nerved, nerves scabrous, especially the subcentral and submarginal nerves, central zone often broad, appressed hairy. Superior glume 1/3–2/3 of the spikelet, ovate to oblong triangular, 3-nerved, appressed hairy, hairs fine, smooth, acute. Inferior glume short, triangular, sometimes truncate or even slightly bifid. Pedicels 2-nate, 0.3–3 mm. long, triangular, scabrous, scarcely widened at the apex. Rhachis triquetrous, broadly winged, up to 0.7 mm. wide, smooth to scaberulous with scabrous margins.
