EOL Text
Annual; culms 20-100 cm high, decumbent at the base and geniculately ascending. Leaf-blades broadly linear, 3-25 cm long, 3-10 mm wide. Inflorescence digitate or subdigitate (axis up to 5 cm long in robust specimens), composed of 2-12 racemes; racemes stiff, 6-22 cm long, sometimes adorned with sparse long white hairs, the spikelets binate and overlapping by about two-thirds their length on a winged rhachis with triquetrous midrib; pedicels triquetrous, scabrid, obtuse or slightly expanded at the tip. Spikelets narrowly elliptic, (2-)2.5-3.3 (-3.7) mm long, sharply acute; lower glume distinct, 0.2-0.4 mm long and triangular; upper glume at least half as long as the spikelet, typically two-thirds to three-quarters as long, 3-nerved; lower lemma as long as the spikelet, 7-nerved, the nerves smooth and evenly spaced or with a wide interspace flanking the midrib (sometimes those of the subsessile spikelet even and of the pedicelled spikelet spaced), appressed puberulous, silky pubescent or rarely shortly villous, often encompassed by a ciliate frill, occasionally glabrous, one or both spikelets often beset with stiff glassy bristles; fruit ellipsoid, grey to light brown.

The following is a representative barcode sequence, the centroid of all available sequences for this species.
Annual. Culms decumbent at base, branching and rooting at lower nodes, 30–100 cm tall. Leaf sheaths ± pilose; leaf blades linear to linear-lanceolate, 5–20 × 0.3–1 cm, adaxial surface usually pilose, margins thickened and scabrous; ligule 1–2 mm. Inflorescence digitate or subdigitate, axis short; racemes 3–10, 5–17 cm; spikelets paired, imbricate by about 2/3 their length; rachis winged, ca. 1 mm broad, midrib triquetrous, margins scabrous. Spikelets lanceolate, 2.5–3.5 mm, acute; lower glume very small, triangular; upper glume lanceolate, 2/3–4/5 as long as spikelet, 3-veined, pilose; lower lemma as long as spikelet, 7-veined, veins evenly spaced or a broader glabrous interspace flanking the midvein, lateral interveins appressed pubescent to ciliate or villous, sometimes with a halo-like fringe, sometimes setose; upper lemma yellowish green, gray or pale brown, elliptic, as long as lower lemma, apex acuminate. Fl. and fr. May–Oct. 2n = 36, 54, 72.
