    Gramineae, T. Cope. Flora Zambesiaca 10:2. 1999

    Habit
    Loosely caespitose perennial arising from a branched, horizontal rhizome, the basal leaves distichous with imbricate sheaths; culms up to 30(75) cm tall, suberect, unbranched; basal leaf sheaths coriaceous and glossy, glabrous, terete, persistent; basal leaf laminas 1–3 cm× 1.5–3 mm, the lowermost broadly triangular, cauline leaf laminas up to 11 cm long, stiff, green or rarely glaucous, tightly involute or the basal sometimes flat, glabrous beneath, pubescent above, the margins conspicuously white-cartilaginous and thicker than the lamina, apiculate to pungent at the apex.
    Inflorescences
    Panicle 7–16 cm long, ovate to ovate elliptic, very diffuse; primary branches not in whorls, subdichotomously branched, the branchlets and pedicels capillary, smooth, eglandular, widely diverging, with a distinct pulvinus in the axils, this quite glabrous, the spikelets evenly distributed.
    Spikelets
    Spikelets 1.3–2(2.5) mm long, pallid; glumes unequal, ovate to elliptic, hyaline, nerveless, glabrous, obtuse at the apex, the inferior 2/5–3/5 the length of the spikelet, the superior 2/3–4/5 the length of the spikelet or more (but very rarely as long as it); lemma as long as the spikelet, hyaline, 3-nerved, ovate-elliptic, obtuse at the apex; anthers 3, (0.5)0.7–1.2 mm long.
    Fruits
    Grain 1.3–2(2.5) mm long, obovate.
    [GB]
    Habit
    Perennial; mat forming. Rhizomes elongated. Culms 15-43 cm long; 2-5 -noded. Leaves basal and cauline. Ligule a fringe of hairs. Leaf-blades 4-12 cm long; 2-3 mm wide. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence a panicle. Panicle open; elliptic, or ovate; effuse; 6-15 cm long. Primary panicle branches branching dichotomously. Panicle branches capillary; glabrous in axils. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 1-2 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 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes deciduous; similar; shorter than spikelet; similar to fertile lemma in texture. Lower glume lanceolate; 0.33-0.5 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume lanceolate; 0.5-0.75 length of adjacent fertile lemma; hyaline; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume apex obtuse.
    Florets
    Fertile lemma ovate; 1-2 mm long; membranous; without keel; 1 -veined. Lemma apex acute. Palea 2 -veined. Palea keels approximate.
    Flowers
    Anthers 3.
    Fruits
    Caryopsis with free soft pericarp.
    Distribution
    Africa: southern tropical and south.
