Characteristics

Hard, robust perennial, 400-600(-900) mm high; stoloniferous, underground parts thick and creeping; profusely rooting at nodes; culms often branched below with tufts of leaves from nodes. Leaf blade 200-400(-500) x 5-7 mm; flat at first, rolled later, rigid, sharp-pointed; ligule an unfringed membrane. Inflorescence a true spike, 60-250 mm long, spikelets arranged alternately, appressed to rachis, not secund, solitary, sessile to subsessile; rachis disarticulating, spikelets falling with internode below. Spikelet (15)28-40 mm long, hard, smooth, falling with glumes, laterally compressed, awnless; glumes ± equal, shorter than spikelet. Florets 5-11; lowest florets bisexual; lemma similar in texture to glumes, glabrous, 5-nerved, usually 3-toothed, awned; awn minute, straight; anther 6.0-7.0 mm long. Flowering time Oct.-Jan.
