    [GB]
    Habit
    Perennial. Stolons absent, or present. Culms geniculately ascending; 8-60 cm long; rooting from lower nodes. Ligule a fringe of hairs. Leaf-blades 3-55 cm long; 1-8 mm wide.
    Inflorescences
    Inflorescence a panicle. Panicle contracted; elliptic; 2-11 cm long. Spikelets solitary. Fertile spikelets pedicelled. Pedicels linear.
    Spikelets
    Spikelets comprising 2-6 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 9-18 mm long; falling entire; readily shedding fertile florets. Spikelet callus linear; 2.5 mm long; bearded; base truncate. Spikelet callus hairs 0.3 length of spikelet. Floret callus elongated; 1.5-2 mm long; pubescent; with longer hairs above; pungent.
    Fertile
    Spikelets comprising 2-6 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 9-18 mm long; falling entire; readily shedding fertile florets. Spikelet callus linear; 2.5 mm long; bearded; base truncate. Spikelet callus hairs 0.3 length of spikelet. Floret callus elongated; 1.5-2 mm long; pubescent; with longer hairs above; pungent.
    Glume
    Glumes dissimilar; with lower wider than upper; exceeding apex of florets; firmer than fertile lemma. Lower glume ovate; 9-18 mm long; 1 length of upper glume; chartaceous; 1-keeled; keeled above; 5-10 -veined. Lower glume primary vein scabrous. Lower glume apex acute. Upper glume lanceolate; 9-18 mm long; 3 length of adjacent fertile lemma; chartaceous; without keels; 3-5 -veined. Upper glume apex acute.
    Florets
    Fertile florets with the lowest dissimilar (deciduous with glumes). Lowest fertile lemma glabrous, or hairy; awned (often 1-awned and entire). Fertile lemma oblong; 2.5-5 mm long; cartilaginous; without keel; 7-9 -veined. Lemma surface pubescent. Lemma apex lobed; 2 -fid; incised 0.3 of lemma length; awned; 3 -awned. Principal lemma awn from a sinus; geniculate; 6-10 mm long overall; with twisted column. Lateral lemma awns arising on inner edge of lobes; 2-4 mm long; shorter than principal. Palea 1 length of lemma; 2 -veined. Palea keels approximate.
    Flowers
    Lodicules 2; glabrous.
    Fruits
    Caryopsis with adherent pericarp. Hilum linear; 0.8-0.9 length of caryopsis.
    Distribution
    Africa: south.
