Morphology General Habit
Loosely caespitose annual, culms up to 70 cm tall, erect or ascending, branched or unbranched, glabrous at the nodes, glandular or eglandular; leaf sheaths glabrous; ligule a line of hairs; leaf laminas 2–20 cm × 1–4 mm, linear, flat, glabrous, eglandular.
Morphology Reproductive morphology Inflorescences
Panicle 4–25 cm long, elliptic or ovate, open, the spikelets evenly distributed on pedicels 2–6 mm long, the lowermost primary branches in a whorl (except in smaller specimens), the remainder not so, terminating in a fertile spikelet, thinly long-pilose in the axils (especially, and sometimes only, in the whorled branches), eglandular or sometimes with scattered crateriform glands.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets 3–7 × 0.7–1.2 mm, linear, lightly laterally compressed, 4–14-flowered, the florets disarticulating from below upwards, the rhachilla persistent; glumes very unequal, the inferior 0.5–0.7 mm long, reaching to c. 1/5 the way along the adjacent lemma, keeled, lanceolate in profile, glabrous, obtuse at the apex; the superior 0.7–1 mm long, reaching to c. 1/4 the way along the adjacent lemma, keeled, narrowly ovate in profile, glabrous, subacute at the apex; lemmas 1–1.6(1.8) mm long, keeled, narrowly ovate in profile, thinly membranous with distinct lateral nerves, appressed to the rhachilla but those in opposite rows scarcely imbricate and the rhachilla ± visible between them, purplish-green, glabrous, subacute to obtuse at the apex; palea deciduous soon after the lemma, glabrous on the flanks, the keels slender, wingless, scaberulous; anthers 3, 0.2–0.3 mm long.
Morphology Reproductive morphology Fruits
Caryopsis 0.6–1 mm long, elliptic but with one side straight, somewhat laterally compressed.
