    Habit
    Annual. Culms geniculately ascending; 28-70 cm long. Ligule a fringe of hairs. Leaf-blade margins cartilaginous.
    Inflorescences
    Inflorescence composed of racemes. Racemes borne along a central axis; unilateral. Rhachis angular. Spikelets appressed; solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 2 fertile florets; without rhachilla extension, or with diminished florets at the apex. Spikelets lanceolate; subterete; 5-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent.
    Fertile
    Spikelets comprising 2 fertile florets; without rhachilla extension, or with diminished florets at the apex. Spikelets lanceolate; subterete; 5-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent.
    Glume
    Glumes lower persistent, upper deciduous; exceeding apex of florets; firmer than fertile lemma. Lower glume lanceolate; 0.8-0.9 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 1.8-2 length of adjacent fertile lemma; membranous; without keels; 1 -veined. Upper glume apex acute.
    Florets
    Fertile lemma elliptic; membranous; without keel; 3 -veined. Lemma midvein pubescent. Lemma margins ciliate. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus. Palea 2 -veined. Palea keels ciliate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Anthers 3.
    Fruits
    Caryopsis with adherent pericarp; ellipsoid; dorsally compressed; plano-convex.
    Distribution
    Africa.

    Habit
    Annual
    Leaves
    Leaf-blades linear, short; ligule a narrow ciliate membrane
    Inflorescences
    Inflorescence open, erect, consisting of a number of slender subsecund racemes scattered along a central axis
    Spikelets
    Spikelets narrow, terete, subsessile, appressed to the rhachis of the racemes, 2–3-flowered, the florets tightly enclosed within the overlapping glumes, disarticulating between the florets, the rhachilla filiform; glumes 1-nerved, as long as the spikelet, membranous, rounded on the back, slightly unequal; lemmas 3-nerved, thinly membranous, rounded on the back, densely villous along the lateral nerves, awned from the 2-lobed tip; awn straight, fine; palea densely villous on the upper part of the keels; anthers 3; callus pointed, appressed villous and laterally bearded
    Fruits
    Caryopsis elliptic-oblong, plump, slightly flattened on the hilar side.
