Characteristics

Tufted perennial, 0.7-1.3 mm high; old leaves break off above sheath mouth, remaining leaf bases sometimes split along midrib and two halves curl away from each other. Leaf blade up to 650 x 1.3 mm; ligule a fringe of hairs. Inflorescence a loosely contracted panicle, 170-270 mm long, interrupted, shortly branched. Spikelets up to 13 x 6 mm (including awns), laterally compressed; glumes ± equal, 9-14 mm long, 1-3-nerved. Florets (2)3 or 4; lemmas 10 mm long, with 3 equally spaced tufts of white hairs on either side of central nerve, tufts on margins mostly basal; lobes usually fully adnate to central awn; central awn 5-8 mm long, seldom geniculate, sometimes basally twisted. Flowering time July-Jan.
