Annual, tufted or with the base of the culms decumbent and forming stolons; culms geniculately ascending, 30–70 cm. high.. Leaf-blades narrowly lanceolate, 2–9 cm. long, 2–10 mm. wide.. Inflorescence of 2–5 digitate racemes; racemes 6–16 cm. long, the spikelets ternate on a ribbon-like winged rhachis with low rounded midrib.. Spikelets elliptic-oblong, 1.5–2.4 mm. long; lower glume a little truncate membranous cuff 0.1–0.3 mm. long; upper glume and lower lemma similar, as long as the spikelet, 5-nerved, obscured by copious soft snow-white (occasionally purplish) fluffy verrucose hairs extending beyond the tip of the spikelet, usually the midnerve exposed, and occasionally the side nerves also visible as glabrous ribs; fruit ellipsoid, golden brown.
Inferior lemma as long as the spikelet, oblong-lanceolate with recurved margins, with 3 prominent nerves and sometimes 2 less developed marginal nerves, appressed hairy, hairs overtopping the spikelet.
Superior glume somewhat shorter than the spikelet, oblong triangular, with 3 prominent nerves, appressed hairy, hairs white to purplish, undulating, with a rough, papillose wall.
Leaf laminae 4–9 × 0.4–1 cm., linear, flat, glabrous on both surfaces, sometimes minutely scaberulous, margins scaberulous, crisped.
Superior lemma somewhat shorter than the spikelet, oblong-lanceolate, apiculate, pale yellow to pale brown.
Inflorescence composed of 2–4 racemes, (5)97–14 cm. long, erect, solitary along a short common axis.
Rhachis triquetrous, broadly winged, up to 1 mm. broad, smooth with scaberulous margins.
Pedicel 3-nate, 0.5–3 mm. long, subterete, smooth, slightly broadened at the apex.
Culms 40–70 cm., erect or ascending, glabrous, nodes dark, glabrous.
A loosely caespitose annual (or short-living perennial?).
Spikelets 2.0–3.0 mm. long, oblong-lanceolate.
Inferior glume rim-like or absent.
Ligule 0.5–1 mm. long, rim-like.
Tufted or trailing annual.
Leaf sheaths glabrous.
