    Habit
    Perennial. Culms decumbent; 30-80 cm long; rooting from lower nodes. Ligule a fringe of hairs.
    Inflorescences
    Inflorescence composed of racemes; terminal and axillary. Racemes single. Rhachis fragile at the nodes; semiterete. Rhachis internodes cuneate. Rhachis internode tip transverse; cupuliform. Spikelets squeezed between internode and pedicel; in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels cuneate.
    Sterile
    Companion sterile spikelets well-developed; deciduous with the fertile.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 5-8 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pilose; base obtuse; inserted. Companion sterile spikelets well-developed; deciduous with the fertile.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 5-8 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pilose; base obtuse; inserted.
    Glume
    Glumes exceeding apex of florets; firmer than fertile lemma. Lower glume lanceolate; cartilaginous; 2-keeled. Lower glume intercarinal veins absent. Lower glume surface deeply depressed. Lower glume apex acute. Upper glume ovate; cartilaginous; 1-keeled; winged on keel; 7 -veined. Upper glume apex truncate.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret oblong; hyaline; 3 -veined; acute. Fertile lemma oblong; hyaline; without keel; 3 -veined. Lemma apex lobed; 2 -fid; incised 0.33 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate. Palea hyaline; 2 -veined.
    Distribution
    Africa.

    Habit
    Perennial
    Leaves
    Leaf-blades broadly linear; ligule a line of hairs
    Inflorescences
    Inflorescence a solitary raceme, these terminal and axillary; internodes and pedicels swollen, ± clavate, ciliate
    Sessile
    Sessile spikelet laterally compressed; callus obtuse and fitting the concave top of the internode; lower glume cartilaginous, 2-keeled, the keels dorsal, almost contiguous, separated by a narrow groove, not winged; upper glume strongly compressed, conspicuously winged towards the top of the keel; lower floret ♂, with hyaline lemma and well-developed palea; upper lemma bifid, passing between the teeth to a glabrous awn
    Fruits
    Caryopsis narrowly ellipsoid
    Spikelets
    Pedicelled spikelet larger than the sessile, glabrous, asymetrically winged, awnless, conspicuous. Sessile spikelet laterally compressed; callus obtuse and fitting the concave top of the internode; lower glume cartilaginous, 2-keeled, the keels dorsal, almost contiguous, separated by a narrow groove, not winged; upper glume strongly compressed, conspicuously winged towards the top of the keel; lower floret ♂, with hyaline lemma and well-developed palea; upper lemma bifid, passing between the teeth to a glabrous awn
    Pedicelled
    Pedicelled spikelet larger than the sessile, glabrous, asymetrically winged, awnless, conspicuous.
