INFLORESCENCE Inflorescence composed of racemes; embraced at base by subtending leaf.

Racemes 1; single; unilateral; 2–15 cm long. Rhachis subterete. Spikelet packing broadside to rhachis; with lowest internode elongated; 2 -rowed.

Spikelets appressed; solitary. Fertile spikelets sessile; heteromorphic (lowest female, larger).

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; truncate; 3 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; exceeding apex of florets; similar to fertile lemma in texture. Lower glume oblong; 3 mm long; 1 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface asperulous. Lower glume apex obtuse. Upper glume oblong; 3 mm long; 1.5 length of adjacent fertile lemma; membranous; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume surface asperulous. Upper glume apex obtuse.

FLORETS Fertile lemma ovate; 2 mm long; membranous; without keel; 5 -veined. Lemma surface pubescent. Lemma apex erose; truncate. Palea 0.75 length of lemma; 2 -veined. Palea surface pubescent; hairy on back and on flanks.

FLOWER Lodicules absent. Anthers 3; 2 mm long. Stigmas pubescent.

FRUIT Caryopsis with adherent pericarp; ellipsoid; laterally compressed; 1.5 mm long. Hilum elliptic; 0.3 length of caryopsis.

DISTRIBUTION Africa: north.
