    Gramineae, W. D. Clayton, S. M. Phillips & S. A. Renvoize. Flora of Tropical East Africa. 1974

    Habit
    Perennial mat-forming tussock grass; culms 15–63 cm. high, fairly slender, ascending from a prostrate base, rooting and branching at the lower nodes.
    Leaves
    Leaf-blades 3–18 cm. long, 3.5–9.5 mm. wide, rather glaucous, acuminate, blades and sheaths usually glabrous; ligule 1–1.5 mm. long.
    Inflorescences
    Inflorescence open to fairly compact, composed of 5–10 spikes on an axis 3.5–11 cm. long; spikes oblong to ovate, 1.2–3.5 cm. long, ascending at first, becoming reflexed.
    Spikelets
    Spikelets 8–18-flowered, elliptic-oblong to oblong, 6–14 mm. long, pale green with dark green nerves, often tinged with purple; lower glume 1–3-nerved, lanceolate in profile, 1.7–3.5 mm. long, acute and mucronate; upper glume 7–9-nerved, lanceolate-oblong, 3.8–6.8 mm. long, a third to half as long as the spikelet, sharply acuminate; lemmas 3-nerved, elliptic in profile, 3.6–4.7 mm. long, villous on the lower third of the keel and towards the base on the margins, the marginal nerves ± 2/3 as long as the lemma, the tip obtuse to acute, mucronate; palea-keels not or only very narrowly winged, conspicuously scabrid; anthers 1.7–2.4 mm. long.
    Fruits
    Grain elliptic-oblong, 1.2 mm. long.
    Habitat
    Damp situations in Acacia bushland; 500–1200 m.
    Distribution
    not known elsewhere K6 T2 T3
    [GB]
    Habit
    Perennial; caespitose. Culms decumbent; 15-63 cm long; rooting from lower nodes. Ligule an eciliate membrane; 1-1.5 mm long; lacerate; truncate. Leaf-blades 3-18 cm long; 3.5-9.5 mm wide; glaucous. Leaf-blade surface glabrous. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence composed of racemes. Racemes 5-10; borne along a central axis; deflexed, or ascending; oblong to ovate; unilateral; 1.5-3.5 cm long. Central inflorescence axis 3.5-11 cm long. Rhachis deciduous from axis; flattened. Spikelet packing broadside to rhachis; crowded; regular; 2 -rowed. Spikelets spreading; solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 8-18 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed strongly; 6-14 mm long; falling entire; deciduous with accessory branch structures; readily shedding fertile florets. Rhachilla internodes suppressed between florets.
    Fertile
    Spikelets comprising 8-18 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed strongly; 6-14 mm long; falling entire; deciduous with accessory branch structures; readily shedding fertile florets. Rhachilla internodes suppressed between florets.
    Glume
    Glumes dissimilar; shorter than spikelet; recurved at apex. Lower glume lanceolate; 1.7-3.5 mm long; 0.5 length of upper glume; chartaceous; 1-keeled; 1-3 -veined. Lower glume apex acute; mucronate. Upper glume lanceolate; 3.8-6.8 mm long; 1-1.5 length of adjacent fertile lemma; 1-keeled; 7-9 -veined. Upper glume lateral veins ribbed. Upper glume apex acuminate.
    Florets
    Fertile lemma elliptic in profile; 3.6-4.7 mm long; chartaceous; keeled; 3 -veined. Lemma midvein pubescent; hairy below. Lemma margins pubescent; hairy below. Lemma apex obtuse, or acute; mucronate. Palea straight; 2 -veined. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Anthers 3; 1.7-2.4 mm long.
    Fruits
    Caryopsis with tardily free pericarp; ellipsoid; isodiametric; trigonous; 1.2 mm long.
    Distribution
    Africa: east tropical.
