    [GB]
    Habit
    Perennial; caespitose. Culms 60-90 cm long. Ligule a fringe of hairs. Leaf-blades 3-6 cm long; 2-4 mm wide. Leaf-blade margins cartilaginous.
    Inflorescences
    Inflorescence a panicle. Panicle open; elliptic; 6-10 cm long. Panicle branches capillary. Spikelets in pairs, or in threes. Fertile spikelets pedicelled; 2-3 in the cluster; subequal. Pedicels free; filiform; unequal; 5-25 mm long.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 6-10 mm long; falling entire; deciduous with the pedicel; readily shedding fertile florets; pedicel base hooked. Floret callus elongated; 1 mm long; pubescent; truncate.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 6-10 mm long; falling entire; deciduous with the pedicel; readily shedding fertile florets; pedicel base hooked. Floret callus elongated; 1 mm long; pubescent; truncate.
    Glume
    Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 4-6 mm long; 0.5-0.66 length of spikelet; chartaceous; dark brown; without keels; 3 -veined. Lower glume surface hispid; hairy on veins; with tubercle-based hairs. Lower glume apex acute. Upper glume lanceolate; 6-10 mm long; 1 length of spikelet; chartaceous; dark brown; without keels; 3 -veined. Upper glume surface hispid; hairy on veins; with tubercle-based hairs. Upper glume apex acuminate.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; lanceolate; 6-10 mm long; 1 length of spikelet; chartaceous; 3 -veined; acuminate. Fertile lemma oblong; 4.5 mm long; coriaceous; without keel; 5 -veined. Lemma surface pubescent; with a transverse row of hair tufts; bearing 2 hair tufts in all. Lemma margins involute; interlocking with palea keels. Lemma apex lobed; 2 -fid; incised 0.25 of lemma length; awned; 3 -awned. Principal lemma awn from a sinus; geniculate; flat below; 15-18 mm long overall; with twisted column; deciduous; abscissing from top of lemma. Lateral lemma awns arising on apex of lobes; 5-6 mm long; shorter than principal. Palea 2 -veined. Palea keels contiguous above a sulcus; thickened.
    Flowers
    Anthers 3; 2 mm long.
    Fruits
    Caryopsis with adherent pericarp.
    Distribution
    Africa: west tropical.
