Morphology General Habit
Annual. Culms erect; 60-180 cm long. Ligule a fringe of hairs. Leaf-blades 8-60 cm long; 3-12 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes numerous; borne along a central axis; unilateral; 3-6 cm long. Central inflorescence axis 6-25 cm long. Rhachis angular; pubescent on surface, or pilose on surface. Spikelet packing irregular. Spikelets in pairs. Fertile spikelets pedicelled. Pedicels oblong.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acuminate; 3.5-5 mm long; falling entire. Spikelet callus globular; incorporating lowest rhachilla internode with adnate lower glume; glabrous.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acuminate; 3.5-5 mm long; falling entire. Spikelet callus globular; incorporating lowest rhachilla internode with adnate lower glume; glabrous.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes one the lower absent or obscure; exceeding apex of florets; thinner than fertile lemma. Upper glume elliptic; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume surface pubescent, or pilose. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 1-3 mm long.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets male, or barren; with palea. Lemma of lower sterile floret similar to upper glume; elliptic; 0.9 length of spikelet; 5 -veined; pubescent, or pilose; acuminate; mucronate. Fertile lemma elliptic; 2-2.5 mm long; indurate; without keel. Lemma surface granulose. Lemma margins involute. Lemma apex obtuse; mucronate. Principal lemma awn 1-2 mm long overall. Palea involute; indurate.
Distribution
Africa: east tropical, southern tropical, and south.
