    [GB]
    Habit
    Perennial; caespitose. Rhizomes short. Basal innovations flabellate. Culms erect, or geniculately ascending; 60-120 cm long. Culm-internodes elliptical in section. Lateral branches sparse. Leaf-sheaths keeled. Ligule a ciliolate membrane; 0.6-1 mm long. Leaf-blades flat, or conduplicate; 15-50 cm long; 4-7 mm wide. Leaf-blade surface pilose; hairy adaxially. Leaf-blade margins smooth (except near tip); glabrous. Leaf-blade apex acute.
    Inflorescences
    Inflorescence composed of racemes. Racemes 4-15; digitate; distant; spreading, or ascending; unilateral; 5-12 cm long. Central inflorescence axis 0-7 cm long. Rhachis wingless; flattened. Spikelet packing broadside to rhachis; regular; 2 -rowed. Spikelets appressed; solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 5-10 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 5-8.3 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.
    Fertile
    Spikelets comprising 5-10 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 5-8.3 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 1-2.2 mm long; 0.5-0.6 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse, or acute. Upper glume oblong; 2-3.6 mm long; 0.8-0.9 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex obtuse, or acute.
    Florets
    Fertile lemma lanceolate in profile, or oblong in profile; 2.5-3.8 mm long; membranous; mid-green and grey; 3 -veined. Lemma midvein simple. Lemma apex obtuse, or acute. Palea 0.9-1 length of lemma; 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; cuneate; fleshy.
    Fruits
    Caryopsis with free soft pericarp; ellipsoid; trigonous; 1.2-1.3 mm long; black; striate.
    Distribution
    Africa: northeast tropical and east tropical.

    Habit
    Tufted perennial from a stout ascending rhizome.
    Culms
    Culms 60–120 cm. high, moderately robust, erect or ascending, branched at the lower nodes.
    Leaves
    Leaf-blades flat or loosely folded, 15–50 cm. long, 4–7 mm. wide, pilose on the upper surface towards the ligule, glabrous towards the tip and on the lower surface, the margins scabrid only near the tip, the tip subacute; ligule 0.6–1 mm. long, a ciliolate membrane.
    Inflorescences
    Inflorescence composed of 4–15 spikes clustered towards the top of the culm, the upper spikes subdigitate; spikes up to 12 cm. long, slender, ascending or occasionally widely spreading.
    Spikelets
    Spikelets 5–10-flowered, elliptic to narrowly elliptic, 5–8.3 mm. long, pale green tinged with grey or olivaceous; glumes 1-nerved, obtuse to subacute, the lower lanceolate in profile, 1–2.2 mm. long, the upper narrowly oblong in profile, 2–3.6 mm. long; lemmas lanceolate-oblong in profile, 2.5–3.8 mm. long, lateral nerves often obscure, tip obtuse to subacute.
    Fruits
    Grain broadly elliptic, 1.2–1.3 mm. long, concave on the hilar side, finely striate.
