Information
Annual; culms 20–80 cm. high, geniculately ascending, often decumbent and rambling. Leaf-blades broadly linear to lanceolate, 2–15 cm. long, 3–17 mm. wide, thin. Inflorescence composed of (3–)7–20 racemes diverging from a common axis 1–7 cm. long, this rarely exceeding the longest raceme; racemes delicate, 3–13 cm. long, the longer occasionally branched near the base, the spikelets binate and overlapping by less than 1/2 their length on a narrowly winged triquetrous rhachis, this sometimes bearing a few long glistening hairs. Spikelets narrowly ovate-elliptic, 1.5–2.1 mm. long, bluntly acute; lower glume obscure or an ovate scale up to 0.2 mm. long; upper glume 2/3–4/5 as long as the spikelet, 3-nerved; lower lemma as long as the spikelet, 7-nerved, the nerves evenly spaced, obscurely and appressedly pubescent, very rarely with a ciliate frill; fruit ellipsoid, mostly grey, sometimes yellowish or purplish brown.

Notes
D. velutina is commonly confused with D. pearsonii. The latter is a rhizomatous perennial, but collectors seldom have patience to trace the straggling culm to its roots. It also has pure brown fruits, those of D. velutina being mostly grey but sometimes dirty brown.
