    [GB]
    Habit
    Perennial; caespitose. Butt sheaths pubescent. Culms erect; 45-100 cm long. Ligule a fringe of hairs. Leaf-blades 4-35 cm long; 3-9 mm wide. Leaf-blade surface hirsute; hairy on both sides. Leaf-blade margins cartilaginous; ciliate.
    Inflorescences
    Inflorescence composed of racemes. Racemes (1-)2-3(-5); borne along a central axis; arcuate; unilateral; 3-13 cm long. Central inflorescence axis 1-15 cm long; tip without extension, or filiform. Rhachis broadly winged; folded longitudinally to embrace spikelets; (1-)2-4 mm wide; scaberulous on margins; glabrous on margins. Spikelet packing adaxial; regular; 2 -rowed. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed strongly; acute; 3.5-4.5 mm long; falling entire.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed strongly; acute; 3.5-4.5 mm long; falling entire.
    Glume
    Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume oblong; 1 length of spikelet; membranous; without keels; 7-9 -veined. Lower glume surface glabrous, or pubescent; without hair tufts, or with a dorsal tuft of hair. Lower glume apex acute. Upper glume oblong; 1.2 length of adjacent fertile lemma; 1 length of spikelet; membranous; without keels; 7-9 -veined. Upper glume lateral veins with cross-veins. Upper glume surface glabrous, or pubescent. Upper glume apex obtuse.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret ovate; 1 length of spikelet; coriaceous; 7-9 -veined; with cross-veins; sulcate (thinly membranous); glabrous, or pubescent; obtuse. Fertile lemma elliptic; 3-4 mm long; indurate; without keel. Lemma surface papillose. Lemma margins involute. Lemma apex obtuse; mucronate. Principal lemma awn 0.2-0.5 mm long overall. Palea involute; indurate; without keels.
    Distribution
    Africa: west-central tropical, east tropical, and southern tropical.

    Spikelets
    Spikelets 3.5–4.5 mm. long, glabrous or pubescent, cuspidate.
    Glume
    Inferior glume as long as spikelet, 7–9-nerved. Superior glume reticulately nerved.
    Lemma
    Inferior lemma reticulately nerved. Superior lemma papillose, with a mucro 0.2–0.5 mm. long.
