    [GB]
    Habit
    Perennial; caespitose. Cataphylls evident. Rhizomes elongated. Culms geniculately ascending; 15-32 cm long. Lateral branches lacking. Leaves cauline; distichous. Leaf-sheaths mostly shorter than adjacent culm internode. Ligule a fringe of hairs. Leaf-blades flat, or involute; 1-6 cm long; 1-5 mm wide; coriaceous; stiff; glaucous. Leaf-blade surface ribbed; pilose; hairy on both sides. Leaf-blade apex acute; pungent.
    Inflorescences
    Inflorescence composed of racemes. Racemes 4-12; borne along a central axis; closely spaced; in a multilateral false spike, or in a head; unilateral; 1-3 cm long; bearing few fertile spikelets; bearing 3-14 fertile spikelets on each. Central inflorescence axis 1-4 cm long. Rhachis subterete. Spikelet packing broadside to rhachis; crowded. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; 0.5-1 mm long.
    Spikelets
    Spikelets comprising 4-9 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; compressed slightly; 5-9 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pilose; obtuse.
    Fertile
    Spikelets comprising 4-9 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; compressed slightly; 5-9 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pilose; obtuse.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 1.8-2.4 mm long; 0.6-0.7 length of upper glume; scarious; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume oblong; 2.7-3.3 mm long; 1-1.2 length of adjacent fertile lemma; scarious; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume surface scabrous; rough on veins. Upper glume apex obtuse.
    Florets
    Fertile lemma ovate; 2.3-3.3 mm long; membranous; without keel; 3 -veined. Lemma midvein ciliate; hairy below. Lemma lateral veins close to margins. Lemma margins ciliate. Lemma hairs 0.75-1 mm long. Lemma apex dentate; 2 -fid; mucronate. Palea 1 length of lemma; 2 -veined. Palea keels scaberulous. Palea surface pubescent. Apical sterile florets resembling fertile though underdeveloped.
    Fruits
    Caryopsis with free soft pericarp; ellipsoid; 1.1-1.2 mm long; dark brown.
    Distribution
    Africa: east tropical, southern tropical, and south.

    Leaves
    Leaf-blades linear-lanceolate, 1–6 cm. long, 1–5 mm. wide, pilose on both sides, often only sparingly, margins scabrid especially towards the tip.
    Inflorescences
    Inflorescence narrowly elliptic to elliptic-oblong, rarely almost linear, 1.5–7 cm. long, brownish or purplish; racemes erect, 1–3 cm. long, with 3–14 spikelets.
    Spikelets
    Spikelets 4–9-flowered, elliptic to narrowly elliptic-oblong, 5–9 mm. long; glumes unequal, scaberulous on the nerve, rounded or slightly keeled, lower glume broadly lanceolate, 1.8–2.4 mm. long, acute, upper glume elliptic-oblong to oblong, 2.7–3.3 mm. long, ± obtuse, sometimes mucronulate; lemmas narrowly ovate, 2.3–3.3 mm. long, membranous with scarious margins, hairs on the lateral nerves 0.75–1 mm. long, the central ones shorter.
    Fruits
    Grain elliptic-oblong, 1.1–1.2 mm. long, chestnut brown, slightly concave on the hilar side; pericarp free.
