HABIT Perennial. Culms 60–87.5–150 cm long. Ligule a fringe of hairs. Leaf-blades stiff.

INFLORESCENCE Inflorescence a panicle.

Panicle open (1), or contracted.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.

FERTILE SPIKELETS Spikelets comprising 2 fertile florets; with a barren rhachilla extension, or with diminished florets at the apex. Spikelets lanceolate (1), or oblong (1); laterally compressed; 4–5.037–6 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite. Floret callus elongated; bearded.

GLUMES Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 0.8–0.9–1 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface without pits. Lower glume apex acuminate; awned. Upper glume lanceolate; 0.8–1–1.2 length of adjacent fertile lemma; membranous; without keels; 1 -veined. Upper glume apex acuminate; awned; 1 -awned.

FLORETS Fertile lemma elliptic; scarious; without keel; wingless; 3 -veined. Lemma surface unwrinkled; without grooves. Lemma margins ciliate. Lemma apex entire, or dentate (1); 2 -fid (1/1); acute; awned. Principal lemma awn apical, or from a sinus (1). Palea 0.6–0.65–0.7 length of lemma. Apical sterile florets 0–1 in number; rudimentary. Apical sterile lemmas awned.

FLOWER Lodicules 2.

DISTRIBUTION Africa.
