    Habit
    Annual. Culms erect, or geniculately ascending; 30-60 cm long. Ligule an eciliate membrane.
    Inflorescences
    Inflorescence composed of racemes. Racemes borne along a central axis; spreading; ovate; unilateral. Rhachis deciduous from axis; broadly winged; foliaceous; folded longitudinally to embrace spikelets. Spikelets subtended by an involucre. Fertile spikelets sessile; 1-2 in the cluster. Involucre composed of bristles. Involucral bristles deciduous with the fertile spikelets; flattened; rigid; spinose.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 5.5-7 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; 5.5-7 mm long; falling entire; deciduous with accessory branch structures.
    Glume
    Glumes shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; hyaline; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 0.5 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex obtuse.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; herbaceous; 7-9 -veined; acute. Fertile lemma lanceolate; cartilaginous; without keel. Lemma apex acute. Palea cartilaginous.
    Distribution
    Africa.

    Habit
    Annual
    Leaves
    Leaf-blades flat, linear; ligule hyaline
    Inflorescences
    Inflorescence of deciduous pseudo-racemes, the rhachis of these bearing broad foliaceous wings which enfold the spikelets and involucres to form an ovoid ball; involucre a rigid spinously lacerate scale
    Spikelets
    Spikelets ovate-elliptic, dorsally compressed; lower glume a little hyaline scale; upper glume shorter than the spikelet; lower floret reduced to a laterally winged lemma as long as the spikelet; upper lemma as long as the spikelet, cartilaginous, its flat margins covering 1/2 of the palea
    Fruits
    Caryopsis broadly elliptic, dorsally compressed.
