Characteristics

Annual or short-lived perennial. Culms slender, straggling, rooting at lower nodes, 20–60 cm tall, nodes pubescent. Leaf sheaths loose, glabrous or with tubercle-based hairs or ciliate margins; leaf blades lanceolate or linear-lanceolate, 4–15 × 0.4–1 cm, glabrous or pubescent, base subrounded, margins thicker and scabrous, apex acute or acuminate. Inflorescence axis 3–10 cm; racemes 3–6, 2–4 cm, divergent to reflexed; rachis flat, 0.7–1 mm wide, narrowly winged, nearly glabrous; spikelets single, in 2 rows; pedicels glabrous. Spikelets elliptic to narowly obovate, (3–)3.5–4 mm, glabrous, acute; lower glume broadly ovate, 1/3–1/2 spikelet length, 5–7-veined; upper glume separated from lower glume by a short internode, 5–7-veined; upper lemma finely rugose, apex subacute. Fl. and fr. Sep–Nov. 2n = 72.
More
Creeping annual; culms 10–50 cm. high, ascending from a prostrate base.. Leaf-blades broadly linear to narrowly lanceolate, 2–20 cm. long, 5–10 mm. wide.. Inflorescence of 3–5 racemes on an axis 3–10 cm. long; racemes 2–6 cm. long, bearing the spikelets singly on a narrowly winged rhachis.. Spikelets narrowly elliptic, 3.3–3.7 mm. long, glabrous, acute; lower glume 1/3–1/2 as long as the spikelet, clasping; upper glume separated from the lower by a short internode; upper lemma rugulose, bluntly acute.
An annual or short lived grass. The culms are slender. They are straggling and root at the nodes. It is 20-60 cm tall. The leaf blades are sword shaped and 4-15 cm long by 0.4-1 cm wide. They have thickened edges. The sheaths are loose and longer than the internodes. The flowering stalk has 3-4 widely spaced racemes. These are 2-5 cm long. The spikelets are plump and pointed.
