Densely tufted perennial 450-600 mm high; basal sheaths glabrous; culm without glands below nodes. Leaf blade to 200 x to 3 mm; eglandular. Inflorescence dense, contracted, branches usually ad-pressed to main axis, occasionally spreading; lowest branches not whorled. Spikelet 4-7 x 1.5-2.4 mm, rachilla persistent; lemma and paleas tardily breaking up from base upwards; glumes unequal, acute to subacute, reaching 1/4-1/2 up lemma above; lemma acute to acuminate, mucro sometimes present, lateral nerves distinct due to elongated black oil glands alongside; palea keels wingless, hairs less than 0.1 mm long; anthers 3, 1.0-1.4 mm long.
Densely tufted perennial, 450-600 mm high. Leaf blade up to 200 x 3 mm; ligule a fringe of hairs. Inflorescence a dense, contracted panicle, branches usually appressed to main axis, occasionally spreading. Spikelets 4-7 x 1.5-2.4 mm, laterally compressed; spikelets tardily breaking up between florets; glumes shorter than spikelet, 1-nerved. Florets many; lemma entire, 3-nerved, distinct elongated black patches along lateral nerves; palea keels with hairs < 0.1 mm long; anthers 3, 1.0-1.3 mm long. Flowering time Nov.-June.
Perennial, densely tufted, up to 0.6 m high. Leaf blades up to 200 mm long, up to 3 mm wide. Spikelets 4-7 mm long, 1.5-2.4 mm wide. Inflorescence dense and contracted, branches usually appressed to main axis, occasionally spreading; spikelets tardily breaking up between florets; lemma with distinct elongated black patches along lateral nerves; palea keels with hairs shorter than 0.1 mm; anthers 3, 1.0-1.3 mm long.
Perennial; up to 0.6 m high; densely tufted. Leaf blades up to 200 mm x 3 mm. Flowers: panicle dense and contracted; branches usually appressed to main axis; occasionally spreading; spikelets 4-7 x 1.5-2.4 mm; spikelets tardily breaking up between florets; lemmas with distinct elongated black oil glands along lateral nerves; palea keels with hairs < 0.1 mm long; anthers 3; 1.0-1.3 mm long.
Densely caespitose perennial without rhizomes or stolons; culms up to 60 cm tall, erect, unbranched, glabrous at the nodes, eglandular; basal leaf sheaths glabrous, chartaceous, compressed and keeled, eglandular, persistent; ligule a line of hairs; leaf laminas 11–20 cm × 1.5–3 mm, linear and flat or more usually involute, filiform and flexuous, glabrous or pilose, eglandular.
Panicle 8–15 cm long, linear to narrowly oblong with the branches appressed to the main axis (rarely somewhat spreading), the spikelets evenly distributed on pedicels 0.5–2 mm long, the primary branches not in whorls, terminating in a fertile spikelet, glabrous in the axils, eglandular.
