Morphology General Habit
Annual; caespitose. Glands wart-like (on keel). Culms erect, or geniculately ascending; 10-90 cm long. Ligule a fringe of hairs. Leaf-blades 5-15 cm long; 2-8 mm wide. Leaf-blade margins glandular, or eglandular.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open, or contracted; ovate; dense, or loose; 4-30 cm long. Panicle branches stiff; glandular. Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong; glandular.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 5-60 fertile florets; with diminished florets at the apex. Spikelets oblong, or ovate; laterally compressed; 3-20 mm long; 2-4 mm wide; breaking up at maturity; rhachilla persistent; retaining paleas; tough throughout, or fragile above; with the distal florets falling as a whole.

Morphology General Habit
Loosely caespitose annual; culms up to 90 cm tall, erect or ascending, branched or unbranched, glabrous at the nodes, often with a ring of coalescent glands below the nodes; leaf sheaths glabrous, with or without scattered glandular pits; ligule a line of hairs; leaf lamina 4–15 cm × 2.5–8 mm, linear, flat, glabrous, usually with crateriform glands along the margins.
Morphology Reproductive morphology Inflorescences
Panicle 4–30 cm long, ovate to oblong, fairly dense, contracted, stiffly branched, the spikelets evenly distributed on pedicels 1.5–2.5 mm long, these and the branchlets with scattered crateriform glands, the primary branches not in whorls, terminating in a fertile spikelet, glabrous or pubescent in the axils.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets 3–20 × 2–4 mm, narrowly ovate to narrowly oblong, rarely linear, laterally compressed, 5–60-flowered, the lemmas disarticulating from below upwards, the rhachilla persistent or breaking off above the glumes before all the lemmas have fallen; glumes subequal, 1.5–2.2 mm long, reaching to 3/4 or more the way along the adjacent lemmas, keeled, lanceolate to narrowly ovate in profile, often with one or two crateriform glands on the keel, subacute or acute at the apex; lemmas (1.7)2–2.8 mm long, keeled, ovate to elliptic in profile, chartaceous with distinct lateral nerves, diverging from the rhachilla at c. 45°, those in opposite rows not imbricate, the rhachilla just visible between them, pallid yellowish-green to leaden-grey, often with crateriform glands on the keel, obtuse at the apex; palea persistent, glabrous on the flanks, the keels slender, wingless, scabrid; anthers 3, 0.3–0.4 mm long.
