General Information

Annual. Culms rambling, often rooting at lower nodes, 15–100 cm tall, nodes glabrous or pubescent. Leaves cauline; leaf sheaths puberulous or glabrous, ciliate on margins; ligule ca. 0.2 mm, a ciliolate membrane; leaf blades narrowly ovate to ovate, 5–10 × 1–3 cm, membranous, glabrous or pilose, cross veins present, base amplexicaul, apex finely acute to acuminate. Panicle oblong or ovate in outline, 5–15 cm, much branched; branches delicate, often tangled, glabrous or pilose, glandular patches present. Spikelets asymmetrically borne on the pedicels, ovate or elliptic in outline, 1.5–2 mm, sparsely puberulous to pilose; lower glume ovate, as long as spikelet, hyaline, 1–3-veined, separated by an internode; upper glume as long as spikelet, 5-veined; lower lemma similar to upper glume, palea well developed; upper floret white, scaberulous, shiny.
