Annual; culms 20–60 cm. high, erect or geniculately ascending, seldom stoloniferous. Leaf-blades 3–25 cm. long, 2–7 mm. wide. Inflorescence of (2–)3–6(–9) subdigitate racemes; racemes 3–14 cm. long, the spikelets ternate on a ribbon-like winged rhachis with low rounded midrib. Spikelets elliptic, 1.2–2 mm. long; lower glume an obscure hyaline rim; upper glume 4/5 to as long as the spikelet, 3(–5)-nerved, with short appressed verrucose hairs between the nerves; lower lemma as long as the spikelet, 5–7-nerved, pubescent (often obscurely so) with verrucose hairs; fruit ellipsoid, dark brown to almost black.

Notes
Closely allied to the native species D. longiflora. The two species intergrade to some extent, and there are no infallible characters for separating them. Typically D. violascens is a more erect plant, with 3 or more slender racemes, a smaller upper glume (commonly 3-nerved and noticeably shorter than the spikelet) and a dark-coloured fruit.
