Spikelets 4–9 × c. 1.5 mm, linear with serrate outline, laterally compressed, 5–16-flowered, the florets disarticulating from below upwards, the rhachilla persistent; glumes unequal, sometimes conspicuously so, reaching to between 1/4 and 1/2 the way along the adjacent lemmas, lightly keeled, scaberulous on the keel, subacute to acute at the apex, the inferior 0.2–1.2 mm long, narrowly lanceolate in profile, the superior 1.2–1.5 mm long, lanceolate in profile; lemmas 1.6–2.2 mm long, keeled, semi-ovate-elliptic in profile (with straight keel and gibbous margins), membranous with distinct (sometimes prominent) lateral nerves, slightly diverging from the rhachilla, those in opposite rows not imbricate, the rhachilla visible between them, yellowish to dark green or purple, scabrid on the keel and nerves and on the flanks above, obtuse at the apex; palea deciduous soon after the lemma, glabrous on the flanks, the keels slender, wingless, scaberulous; anthers 3, 0.8–1 mm long.
Tufted perennial, the basal sheaths ± papery and glabrous or obscurely pubescent at the very base; culms 40–90 cm. high.. Leaf-blades flat or rolled, mostly 10–15 cm. long and 2–3 mm. wide.. Panicle ovate-elliptic, 15–30 cm. long, open; branches spreading, often with the spikelets ± condensed about them, 1–8 at a node but not in obvious whorls; spikelets 5–16-flowered, linear, 4–9 mm. long and 1.5 mm. wide, often somewhat serrate in outline, yellowish to dark green, breaking up from the base, the rhachilla persistent; glumes unequal, often conspicuously so, the lower narrowly lanceolate and 0.2–1.2 mm. long, the upper lanceolate .and 1.2–1.5 mm. long; lemmas ovate-elliptic, 1.6–2.2 mm. long, the back straight and the margins gibbous in side view, ± finely scaberulous, often with the lateral nerves prominent, obtuse; palea falling soon after the lemma, the keels scaberulous; anthers 3, 0.8–1 mm. long.. Caryopsis narrowly oblong to fusiform, 1 mm. long.. Fig. 61/2, p. 193.
Tufted moderately slender, erect perennial to 1000 mm high; basal sheaths glabrous or obscurely hairy, often flushed red; culms not densely compacted at base and easily separable, nodes glabrous. Leaf blade to 150 x 2-4 mm, apex long-tapering. Inflorescence open, moderately branched; lowest branches 1-8, whorled or not whorled; pedicels slender; spikelets adpressed to branches. Spikelet 4-9 x 1.5 mm, linear to oblong; rachilla persistent; lemmas and paleas breaking up from the base upwards; glumes unequal, translucent, lanceolate, keels and apex smooth or scaberulous, 1/3-3/4 the length of lemma above; lemma 1.6-2.2 mm long, purple to violet to green, often yellow especially near apex, nerves usually prominent, strongly keeled, keel prominent along entire length, apex obtuse; palea boat-shaped in profile, margins touching or overlapping along entire length, keels a distinct thin line, scabrid, wingless; anthers 3, 0.8-1.0 mm long; caryopsis narrowly oblong to linear.
Moderately slender, erect, tufted perennial, up to 1 m high. Leaf blade up to 150 X 1-4 mm, apex long-tapering. Inflorescence an open, moderately branched panicle, lowest branches 1-8, whorled or not whorled; spikelets appressed to branches; pedicels (except terminal ones) shorter than or as long as spikelets. Spikelets up to 4-9 x 1.5 mm, linear to oblong, laterally compressed; rachilla persistent, lemmas and paleas breaking up from base upwards; glumes shorter than spikelet, 1-nerved, translucent, smooth or scaberulous on keels and apices. Florets many; lemma entire, purple to violet to green, often with yellow especially near apex, 3-nerved, nerves usually prominent, strongly keeled, keel prominent along entire length; palea margins meeting or overlapping along entire length, keels distinct but a narrow line; anthers 3, 0.8-1.0 mm long. Flowering time Dec.-May. Caryopsis narrowly oblong.
Caespitose perennial without rhizomes or stolons; culms up to 90 cm tall, erect or ascending, branched or unbranched, glabrous at the nodes, eglandular; basal leaf sheaths glabrous or obscurely pubescent, chartaceous, suffused with red, compressed and keeled, eglandular, persistent or rarely decaying into parallel fibres; ligule a line of hairs; leaf laminas 10–15 cm × 2–3 mm, linear, flat or involute, glabrous, eglandular.
Panicle 15–30 cm long, elliptic-ovate, open, the spikelets loosely condensed about the primary branches on pedicels 1–3.5 mm long, the primary branches 1–8 at a node but not obviously whorled, terminating in a fertile spikelet, glabrous or thinly long-pilose in the axils, eglandular.
Caryopsis 0.9–1.1 mm long, narrowly oblong to linear.
