    [GB]
    Habit
    Annual; caespitose; clumped loosely. Glands wart-like (leaf), or elongated (panicle). Culms erect; 30-60 cm long. Lateral branches lacking. Leaf-sheaths pilose; outer margin hairy. Ligule a fringe of hairs. Leaf-blades 1.5-9 cm long; 2-5 mm wide. Leaf-blade surface glabrous. Leaf-blade margins glandular; tuberculate-ciliate. Leaf-blade apex acute.
    Inflorescences
    Inflorescence a panicle. Panicle open; lanceolate, or oblong; 5-20 cm long; with spikelets clustered towards branch tips. Primary panicle branches whorled at most nodes. Panicle branches glandular; smooth. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 1-2.1 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 1-2.1 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes deciduous; similar; reaching apex of florets. Lower glume lanceolate; 0.4-0.66 length of upper glume; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex acute, or acuminate. Upper glume elliptic; 1.1 length of adjacent fertile lemma; membranous; red; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.
    Florets
    Fertile lemma elliptic; 1-2.1 mm long; membranous; without keel. Lemma apex acute. Palea 2 -veined. Palea keels approximate.
    Flowers
    Anthers 3; 0.25-0.6 mm long.
    Fruits
    Caryopsis with free soft pericarp; ellipsoid; laterally compressed; 0.7-1.2 mm long.
    Distribution
    Africa: west-central tropical, northeast tropical, east tropical, southern tropical, and western Indian ocean.

    Habit
    Delicate, loosely caespitose annual; culms up to 60 cm tall, erect, unbranched; leaf sheaths chartaceous, loosely pilose above and near the margins, terete; leaf laminas 1.5–9 cm × 2–5 mm, flat, glabrous, pectinate on the margins with stiff tubercle-based setae, these interspersed among raised marginal glands, acute at the apex.
    Inflorescences
    Panicle 5–20 cm long, lanceolate to narrowly oblong; branches in a succession of whorls, smooth, with elongated viscid glandular patches, the spikelets 2–3 on secondary branchlets or (3)6–10(15) directly on the primary branches, the spikelets or branchlets confined to the distal part of the primary branches.
    Spikelets
    Spikelets 1–2.1 mm long, reddish; inferior glume 2/5–2/3 the length of the spikelet, narrowly lanceolate to lanceolate, nerveless, glabrous, acute to acuminate at the apex; superior glume as long as or almost as long as the spikelet, elliptic, 1-nerved, glabrous, acute at the apex; lemma as long as the spikelet, elliptic; anthers 3, 0.25–0.6 mm long.
    Fruits
    Grain broadly elliptic, 0.7–1.2(1.4) mm long, slightly laterally compressed.
