Loosely tufted annual 400-800 mm; culm decumbent, rooting at lower nodes. Leaf blade 20-100 x 3-15 mm. Inflorescence 80-200 mm long, racemes arranged in 8-12 whorls on a central axis, each whorl consists of 4-8 racemes 20-80 mm long; rachis triquetrous, not winged, scaberulous with few bulbous-based hairs at base; pedicel triangular, scaberulous; spikelets solitary or in pairs, widely spaced on axis. Spikelet 1.5-2.5 mm long, hairy, hairs slightly exceeding spikelet; lower glume absent; upper glume shorter than spikelet, 3-nerved, hairy; internode absent; lower lemma as long as spikelet, 5-nerved, hairy; upper lemma shorter than spikelet, pale to dark brown; anthers 1.2-1.4 mm long.
Annual, loosely tufted, up to 0.8 m high. Leaf blades 30-90 mm long, 3-15 mm wide. Culms decumbent and rooting from lower nodes. Spikelets 1.5-2.0 mm long, 1 mm wide. Panicle 80-200 mm long, racemes arranged in 8-12 whorls on a central axis, each whorl consisting of 4-8 racemes, 20-50 mm long; spikelets solitary or in pairs, widely spaced on axis; upper glume as long as spikelet.
Inflorescence composed of 40–100 racemes, (2)3–8 cm. long, the inferior 20–50 in 4–6 whorls of 5–8 racemes, the superior 20–30 racemes solitary along a tall common axis, the racemes in the inferior whorls are conspicuously peduncled.
Leaf laminae 2–10 × 0.5–1.4 cm., lanceolate to linear, flat, glabrous on both surfaces, often with a few bulbous based bristles near the base, scabrous along the margin.
Superior glume somewhat shorter than the spikelet, oblong-lanceolate, 3-nerved, appressed hairy, hairs fine, smooth, acute, slightly overtopping the glume.
Inferior lemma as long as the spikelet, oblong-lanceolate, 5-nerved, nerves equidistant, smooth, appressed hairy, hairs slightly overtopping the lemma.
Rhachis triquetrous, unwinged, scabrous, loosely hairy, at the base with a few bulbous based bristles, scabrous at the margins.
Pedicels 2-nate, 0.2–2.8 mm. long, triangular, scabrous, slightly broadened at the apex.
Superior lemma shorter than the spikelet, oblong-lanceolate, acute, pale to dark brown.
Culms 40–100 cm., ascending, glabrous, nodes dark and glabrous.
Leaf sheaths smooth and glabrous, rarely loosely hairy.
A loosely caespitose or solitary growing annual.
Erect annual with coarse leaves, 1–1·2 m. high.
Spikelets 1.7–2.2 mm. long, oblong-lanceolate.
Ligule c. 1 mm. long, truncate, erose.
Inferior glume absent.
