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

    Habit
    Densely caespitose perennial, the culms arising above a cushion of old leaf sheaths; culms up to 35 cm tall, erect, unbranched; basal leaf sheaths firmly chartaceous, glabrous, terete, strongly ribbed, eventually disintegrating into a cushion of coarse fibres; leaf laminas 2.5–16 cm long, involute-setaceous, glabrous on the surface, smooth on the margins, obtuse at the apex.
    Inflorescences
    Panicle 3–4.5 cm long, narrowly ovate to ovate; the primary branches not in whorls but sometimes in clusters, smooth, eglandular, with a yellow glabrous pulvinus in the axils, the spikelets gathered into clusters at the distal end.
    Spikelets
    Spikelets 1.7–2.4 mm long, lightly or deeply suffused with purple; glumes subequal, c. 1/2 the length of the spikelet, ovate, 1-nerved, obtuse to subacute (sometimes apiculate) at the apex; lemma almost as long as the spikelet (slightly exceeded by the palea), distinctly 3-nerved, elliptic-ovate, subacute at the apex; palea similar to the lemma but 2-nerved; rhachilla shortly produced, 1/5–3/5 the length of the lemma, glabrous, sunk between the close-set keels of the palea; anthers 3, 1.1–1.4 mm long.
    Fruits
    Grain not known.
    [GB]
    Habit
    Perennial; caespitose; clumped densely. Butt sheaths distinctly ribbed; persistent and investing base of culm; with fibrous dead sheaths. Culms erect; 15-35 cm long. Lateral branches lacking. Ligule a fringe of hairs. Leaf-blades filiform; involute; 2.5-16 cm long; 0.5-2 mm wide. Leaf-blade surface glabrous. Leaf-blade margins smooth; glabrous. Leaf-blade apex obtuse.
    Inflorescences
    Inflorescence a panicle. Panicle open; ovate; 3-4.5 cm long. Primary panicle branches not whorled. Panicle branches tangled; eglandular; smooth; glabrous in axils; with prominent pulvini. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; subterete; 1.7-2.4 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 1 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; subterete; 1.7-2.4 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes deciduous; similar; shorter than spikelet. Lower glume ovate; 1 length of upper glume; membranous; purple; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse, or acute. Upper glume ovate; 0.5 length of adjacent fertile lemma; membranous; purple; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume apex obtuse, or acute.
    Florets
    Fertile lemma ovate; 1.7-2.4 mm long; membranous; without keel; 3 -veined. Lemma lateral veins distinct. Lemma apex acute. Palea 2 -veined. Palea keels approximate. Rhachilla extension 0.4-0.6 length of fertile floret; glabrous.
    Flowers
    Anthers 3; 1.1-1.4 mm long.
    Fruits
    Caryopsis with free soft pericarp.
    Distribution
    Africa: southern tropical.
