    [GB]
    Habit
    Annual; caespitose. Butt sheaths pubescent. Culms geniculately ascending; 20-120 cm long. Ligule a fringe of hairs. Leaf-blades 3-30 cm long; 3-16 mm wide.
    Inflorescences
    Inflorescence composed of racemes. Racemes 2-10; borne along a central axis; unilateral; 1-6 cm long. Central inflorescence axis 2-8 cm long. Rhachis angular. Spikelet packing irregular; 2-4 -rowed. Spikelets in pairs. Fertile spikelets sessile and pedicelled.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; compressed strongly; plano-convex; cuspidate; 3.5-6 mm long; falling entire.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; compressed strongly; plano-convex; cuspidate; 3.5-6 mm long; falling entire.
    Glume
    Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 0.66-0.75 length of spikelet; herbaceous; without keels; (3-)5 -veined. Lower glume surface glabrous, or pubescent. Lower glume apex obtuse, or acute. Upper glume ovate; 1 length of spikelet; membranous; without keels; 5-7 -veined. Upper glume surface glabrous, or pubescent. Upper glume apex acute.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 5-7 -veined; glabrous, or pubescent; eciliate on margins, or setose on margins; acute. Fertile lemma orbicular; dorsally compressed; 2-2.5 mm long; indurate; without keel. Lemma surface papillose; unwrinkled, or rugulose. Lemma margins involute. Lemma apex obtuse; mucronate. Principal lemma awn 1 mm long overall. Palea indurate.
    Distribution
    Africa: northeast tropical, east tropical, southern tropical, and south.
