Spikelets 6–13.5 × 0.5–2 mm, linear to narrowly oblong, laterally compressed, 9–13-flowered, the lemmas disarticulating from below upwards, the rhachilla persistent; glumes unequal, keeled, oblong-lanceolate in profile, scaberulous on the keel, acute at the apex, the inferior 0.5–0.8 mm long, reaching to about 1/3 the way along the adjacent lemma, the superior 0.9–1.5 mm long, shorter than the adjacent rhachilla internode or just exceeding the base of the adjacent lemma; lemmas 1.8–2.5 mm long, keeled, semi-ovate in profile (with straight or rarely concave keel and gibbous margins), membranous with prominent lateral nerves, appressed to the rhachilla, those in opposite rows not overlapping, the rhachilla visible between them, olive-green, glabrous but with punctate glands on the nerves, subacute at the apex; palea persistent, glabrous on the flanks, the keels slender, wingless and glabrous to scaberulous or slightly thickened with punctate glands; anthers 3, (0.9)1.6–2 mm long.
Densely tufted perennial to 1000 mm high; basal sheaths strongly compressed, smooth, shiny, glabrous; culm without glands. Leaf blade to 800 x to 4 mm; glands present or absent. Inflorescence branches spreading or ascending; lowest branches not whorled, sometimes clustered; spikelets adpressed to branches. Spikelet 6.0-10.0(13.5) x 0.5-2.0 mm, linear to oblong; rachilla persistent; lemmas and/or paleas breaking up from base upwards; glumes unequal, oblong-lanceolate; lower glume scale-like, reaching up to 1/3 the length of lemma above; upper glume barely reaching or just touching base of lemma above, shorter than rachilla internode; lemma 1.8-2.5 mm long, glabrous, lateral nerves prominent, glandular dots present; palea keels entire, glabrous to scabrid, thickened or not, glandular dots present or absent, margins touching to overlapping, especially at apex; anthers 3, 1.6-2.0 mm long; caryopsis oblong to elliptic.
Perennial, densely tufted, up to 1 m high. Leaf blades up to 800 mm long, up to 4 mm wide. Basal sheaths strongly compressed, smooth and shiny. Spikelets 6-10 mm long, 0.5-2.0 mm wide. Inflorescence branches usually spreading, spikelets appressed to branches; spikelets linear-oblong, with rhachilla persistent, lemmas and/or paleas breaking up from base upwards; lower glume scale-like, reaching up to a third the length of lemma dbove and upper glume barely reaching or just touching base of lemma above in intact spikelet; lemmas with lateral nerves prominent and with glandular dots; palea keels entire, glabrous to scabrid, glandular dots present or absent; anthers 3, 1.6-2.0 mm long. Caryopsis oblong.
Perennial; up to 1 m high; densely tufted. Leaf blades up to 800 x 4 mm; basal sheaths strongly compressed; smooth and shiny. Flowers: panicle with branches usually spreading; spikelets appressed to branches; spikelets 6-10 x 0.5-2.0 mm; spikelets linear-oblong; with rachilla persistent; lemmas and/or paleae breaking up from base upwards; lower glume scale-like; reaching up to 1/3 length of lemma above and upper glume barely reaching or just touching base of lemma above in intact spikelet; lemmas with lateral nerves prominent and with glandular dots; palea keels entire; glabrous to scabrid; glandular dots present or absent; anthers 3; 1.6-2.0 mm long; caryopsis oblong.
Densely tufted perennial, up to 1 m high; basal sheaths strongly compressed, smooth and shiny. Leaf blade up to 800 x 4 mm; ligule a fringe of hairs. Inflorescence branches usually spreading, spikelets appressed to branches. Spikelets 6-10 x 0.5-2.0 mm, linear-oblong, laterally compressed; rachilla persistent, lemmas and/or paleas breaking up from base upwards; glumes shorter than spikelet, 1-nerved. Florets many; lemmas entire, 3-nerved, lateral nerves prominent and with glandular dots; palea keels entire, glabrous to scabrid, glandular dots present or absent; anthers 3, 1.6-2.0 mm long. Flowering time Nov.-May. Caryopsis oblong.
Densely caespitose perennial without rhizomes or stolons; culms up to 90(100) cm tall, strongly compressed below, erect, unbranched, glabrous at the nodes, eglandular; basal leaf sheaths glabrous, chartaceous, strongly compressed, keeled and usually flabellate, eglandular, persistent; ligule a line of hairs; leaf laminas 10–80 cm × 1.5–4 mm, linear, flat or folded, glabrous, eglandular or with punctate glands along the midnerve.
Panicle 10–35 cm long, narrowly oblong to narrowly ovate, the branches ascending or spreading, the spikelets appressed to the branchlets on pedicels 1.5–2 mm long, the primary branches not in whorls (but sometimes loosely clustered), terminating in a fertile spikelet, glabrous or thinly pilose in the axils, eglandular.
A grass that keeps growing from year to year. It grows 1 m high. It forms dense tufts. The leaf sheaths at the base overlap and are flattened.
Perennial to 1 m. Leaves linear, basal sheaths strongly compressed, smooth and shiny. Spikelets in a panicle, appressed, 6-10 x ± 1-2 mm.
Caryopsis (0.8)0.9–1.2 mm long, oblong to elliptic.
