Characteristics

Spikelets 2–9 × 2–4 mm, broadly ovate to oblong, strongly laterally compressed, 2–20-flowered, the florets disarticulating from the apex downwards, the rhachilla fragile; glumes subequal, 1.5–2 mm long, reaching to 2/3 the way along the adjacent lemmas, keeled, lanceolate to narrowly ovate in profile, glabrous on the flanks, scabrid on the keel, acute to very acute at the apex; lemmas 1.7–2 mm long, strongly keeled, broadly ovate in profile, cartilaginous with faint lateral nerves, eventually widely diverging from the rhachilla (c. 90°), their margins becoming inrolled, those in opposite rows not imbricate, the rhachilla clearly visible between them, yellowish-green tinged with grey or purple, glabrous, obtuse at the apex; palea glabrous on the flanks, the keels slender, narrowly winged, the wing margin minutely fimbriate; anthers 3, 0.5–0.6 mm long.
