    [GB]
    Habit
    Annual. Culms geniculately ascending, or decumbent; 20-100 cm long. Ligule a fringe of hairs. Leaf-blades 5-30 cm long; 2-10 mm wide.
    Inflorescences
    Inflorescence a panicle. Panicle spiciform; linear; 4-18 cm long. Primary panicle branches accrescent to a central axis; with sessile scars on axis. Panicle axis angular; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 2(-3) in the cluster. Involucre composed of bristles; connate into a cup below; with 2-6 mm connate; ovate, or globose; 6-9 mm long; base obconical. Involucral bristles deciduous with the fertile spikelets; with an outer whorl of thinner bristles; inner bristles longer than outer; with longest bristle scarcely emergent; 5-9 mm long; flattened; without grooves; rigid; antrorsely scaberulous; pubescent (surface), or ciliate (margins); spinose.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; acuminate; 4-6 mm long; falling entire; deciduous with accessory branch structures.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; acuminate; 4-6 mm long; falling entire; deciduous with accessory branch structures.
    Glume
    Glumes shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 2.5-3 mm long; 0.5 length of spikelet; membranous; without keels; 1-3 -veined. Lower glume apex acute, or acuminate. Upper glume ovate; 2.5-3 mm long; 0.5 length of spikelet; membranous; without keels; 1-3 -veined. Upper glume apex acute, or acuminate.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret ovate; 1 length of spikelet; membranous; 5-7 -veined; puberulous; hairy above; acuminate. Fertile lemma ovate; 4-6 mm long; coriaceous; much thinner on margins; without keel; 5 -veined. Lemma margins flat. Lemma apex acuminate. Palea coriaceous.
    Flowers
    Anthers 3; 2 mm long.
    Fruits
    Caryopsis with adherent pericarp; ellipsoid; dorsally compressed; 2.5 mm long.
    Distribution
    Africa: northeast tropical, east tropical, and southern tropical.
    Reference
