Loosely tufted perennial 500-1300 mm high, rhizomatous and stoloniferous; rhizomes branched, slender, elongate; culms usually straight, erect, nodes glabrous. Leaf blade 60-300 x 2-8 mm, sheaths mostly glabrous. Inflorescence digitate, 3-12 racemes 80-250 mm long; rachis triquetrous, winged, glabrous or scabrous; pedicel scabrous; spikelets paired. Spikelet 2.5-3.2 mm long; lower glume 0.2-0.5 mm long, ovate-triangular; upper glume shorter to as long as spikelet, 3-nerved, hairy; internode absent; lower lemma as long as spikelet, 7-nerved, nerves evenly spaced or with broader central interspaces, usually scabrid (look carefully); upper lemma partly exposed, pale brown, grey or purple; anthers 1.8-2.4 mm long.
