Tufted perennial, (0.25-)0.40-1.20(-1.50) m high; basal leaf sheaths strongly overlapping. Leaf blade (30-)100-300(-440) x (1.3-)2.0-3.5(-4.5) mm, filiform, rolled; ligule a fringe of hairs. Inflorescence a panicle; pedicels glabrous to sparsely hairy. Spikelets (3.2-)3.6-5.0(-5.7) x 2 mm, narrowly ovate, laterally compressed, densely villous with silky white, pink or purplish hairs up to 4 mm long and exceeding beyond apex; glumes unequal; internode between glumes absent or short, up to 0.3(-0.6) mm long; lower glume 0.5-1.0(-1.9) mm long; upper glume as long as spikelet, straight on back, 5(-7)-nerved; mucronate or with awn 1-2(-3) mm long. Florets 2; lower floret male, lemma 5-nerved, awned, palea keels ciliate; upper floret bisexual; lemma hard, smaller than lower lemma; anther 1.4-2.2 mm long. Flowering time Nov.-Sept.
Perennial; up to 1.2 m high; tufted. Leaf blades (30-)100-300(-440) x (1.3-)2.0-3.5(-4.5) mm; rolled; basal leaf sheaths strongly overlapping. Flowers: panicle slightly contracted; branches; branchlets and pedicels often densely covered with hairs up to 4 mm long and prickles; pedicels white or purple; usually stout; straight or slightly wavy; spikelets (3.2-)3.6-5.0(-5.7) x 2 mm; internode between glumes 0.3(-0.6) mm long; lower glume 0.5 mm long; awns 1-2(-3) mm long.
Perennial, tufted, up to 1.2 m high. Leaf blades (30-) 100-300(-440) mm long, (l,3-)2.0-3.5(-4.5) mm wide. Basal leaf sheaths strongly overlapping; leaf blades rolled. Spikelets (3.2-)3.6-5.0(-5.7) mm long, 2 mm wide, often densely covered with hairs up to 4 mm long, white or purple; internode between glumes 0.3(-0.6) mm long; lower glume 0.5 mm long and awns 1-2(-3) mm long.
