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.
Tufted annual to 500 mm high, erect, geniculate; sticky glands present all over plant, especially just below nodes (noticeable due to particles adhering to them); strong smelling when fresh. Leaf blade 40-100 x 2-5 mm. Inflorescence dense, branches spreading; lowest branches not in whorls; sticky glandular patches present; spikelets distant. Spikelet 2-3 x 1.0-1.5 mm; rachilla fragile, breaking up from apex downwards; glumes subequal, keels glandular; lemma keel glabrous, lateral nerves distinct; palea keel hairs 0.4-0.5 mm long, hairs bulbous-based, exserted from lemma; anthers 3, 0.1-0.3 mm long; caryopsis elliptic.
Annual, tufted (erect and geniculate), up to 500 mm tall. Leaf blades 40-100 mm long, 2-5 mm wide. Spikelets 2-3 mm long, 1.0-1.5 mm wide. Inflorescence with sticky glands (noticable due to particles adhering to them), open, with branches spreading and spikelets distant; spikelets with rhachilla fragile, breaking up from apex downwards; lemma keel glabrous, palea keels with hairs 0.4-0.5 mm long and exserted from lemma; anthers 3, 0.1-0.3 mm long.
Annual; up to 0.5 m high; tufted; erect and geniculate. Leaf blades 40-100 x 2-5 mm. Flowers: panicle open; with branches spreading and spikelets distant; sticky glands (noticeable due to particles adhering to them) present; spikelets 1.5-4.5 x 1.0-1.5 mm; spikelets with rachilla fragile; breaking up from apex downwards; lemma keels glabrous; palea keels with bulbous-based hairs 0.4-0.5 mm long and exserted from lemma; anthers 3; 0.1-0.3 mm long.
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.
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.
Lower glume with a sticky yellow mid-nerve: dry sandy soils.
Caryopsis 0.5–0.7 mm long, narrowly elliptic.
Culms, leaf-sheaths and base of blade sticky
Annual, 20–45 cm. high
