Perennial, 500-700 mm high; rhizomes stout. Leaf blade up to 250 x 4 mm; ligule a fringe of hairs. Inflorescence an ovate to orbicular panicle, branches fairly rigid, spreading; pedicels 3x length of spikelets, spreading. Spikelets 6-8(-15) x 1.5-3.0 mm, grey-green, laterally compressed; rachilla persistent, becoming fragile in upper portion; glumes shorter than spikelet, 1-nerved. Florets many; lemma acuminate, entire, 3-nerved, lateral nerves distinct; palea oblanceolate, thick-textured, apex acute to subacute, keels entire, forming a prominent ridge, shortly ciliolate; anthers 3, 0.8-1.0 mm long. Flowering time Nov.-Mar. Caryopsis elliptic.
