    [GB]
    Habit
    Perennial; caespitose. Butt sheaths woolly. Culms 60-100 cm long. Ligule a fringe of hairs. Leaf-blades 10-40 cm long; 5-20 mm wide.
    Inflorescences
    Inflorescence composed of racemes. Racemes 6-20; borne along a central axis; unilateral; 3-10 cm long. Central inflorescence axis 5-10 cm long. Rhachis angular; glabrous on surface, or with scattered hairs. Spikelet packing abaxial; irregular; 2-4 -rowed. Spikelets solitary, or in pairs. Fertile spikelets sessile and pedicelled, or sessile.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; compressed strongly; plano-convex; acuminate; 3.5-5 mm long; falling entire.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; compressed strongly; plano-convex; acuminate; 3.5-5 mm long; falling entire.
    Glume
    Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 0.66-0.75 length of spikelet; herbaceous; without keels; 5 -veined. Lower glume surface glabrous, or pubescent. Lower glume apex obtuse, or acute. Upper glume lanceolate; 1 length of spikelet; membranous; without keels; 7 -veined. Upper glume surface glabrous, or pubescent. Upper glume apex acuminate.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; lanceolate; 1 length of spikelet; membranous; 5 -veined; glabrous, or pubescent; eciliate on margins, or setose on margins; acuminate. Fertile lemma elliptic; dorsally compressed; 2 mm long; indurate; without keel. Lemma surface granulose; rugulose. Lemma margins involute. Lemma apex obtuse; mucronate. Principal lemma awn 0.3-0.5 mm long overall. Palea indurate.
    Distribution
    Africa: west-central tropical, northeast tropical, east tropical, southern tropical, and south. Australasia: Australia.

    Habit
    Tufted perennial, the base silky tomentose.
    Culms
    Culms 20–120 cm. high, ascending.
    Leaf lamina
    Leaf laminae broadly linear.
    Inflorescences
    Inflorescence of 2–20 racemes, these bearing mostly paired spikelets on a subtriquetrous rhachis, the latter with or without sparse bristles.
    Spikelets
    Spikelets 3.5–6 mm. long, lanceolate to narrowly ovate, glabrous, pubescent or setosely fringed, acuminate.
    Glume
    Inferior glume 2/3–3/4 length of spikelet, lanceolate, 5–nerved, membranous to herbaceous, without a central tuft of bristles, narrowly obtuse to acute.
    Inferior
    Inferior glume 2/3–3/4 length of spikelet, lanceolate, 5–nerved, membranous to herbaceous, without a central tuft of bristles, narrowly obtuse to acute.
    Lemma
    Superior lemma granulose to rugulose, with a mucro 0.3–1 mm. long.
    Superior
    Superior lemma granulose to rugulose, with a mucro 0.3–1 mm. long.
