Morphology General Habit
Loosely caespitose annual; culms up to 40 cm tall, erect, branched or unbranched, glabrous at the nodes, with sticky glandular patches below the nodes; leaf sheaths with sticky glandular patches below the collar; ligule a line of hairs; leaf laminas 4–10 cm × 2–5 mm, linear, flat or with involute margins, glabrous to scattered-pilose, the hairs sometimes with tuberculate base, the midline and margins sticky towards the base.
Morphology Reproductive morphology Inflorescences
Panicle 4–15 cm long, ovate to narrowly oblong, rather dense, the spikelets evenly but rather densely distributed on short stiff pedicels 1.5–2 mm long, the primary branches not in whorls, terminating in a fertile spikelet, glabrous or pilose in the axils, the branches and pedicels sticky from yellowish oblong glandular patches.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets 1.5–4.5 × 1.2–2 mm, ovate-oblong, lightly laterally compressed, 5–15-flowered, the florets disarticulating from the apex downwards, the rhachilla fragile; glumes subequal, 0.6–1.2 mm long, reaching to just beyond the middle of the adjacent lemmas, lightly keeled, the keel thickened by a linear sticky yellow gland, lanceolate in profile, acute at the apex; lemmas 0.7–1.4 mm long, lightly keeled, oblong-elliptic in profile, membranous with distinct lateral nerves, diverging from the rhachilla at c. 45°, those in opposite rows not imbricate, the rhachilla visible between them, yellowish to purplish, glabrous, broadly obtuse and sometimes obscurely mucronate at the apex; palea glabrous on the flanks, the keels slender, wingless, ciliate with tubercle-based hairs 0.1–0.5 mm long; anthers 3, 0.2–0.3 mm long.
