    [GB]
    Habit
    Perennial. Rhizomes elongated; scaly. Culms erect; 30-150 cm long. Ligule an eciliate membrane; 1-2 mm long; pubescent on abaxial surface; erose. Leaf-blade base with a false petiole. Leaf-blades lanceolate; 10-40 cm long; 10-35 mm wide. Leaf-blade venation with distinct cross veins. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; unilateral; 11-30 cm long. Rhachis semiterete; pubescent on surface. Spikelet packing broadside to rhachis; regular; 1 -rowed. Spikelets appressed; solitary. Fertile spikelets pedicelled. Pedicels 1-2 mm long.
    Spikelets
    Spikelets comprising 2-4 fertile florets; with diminished florets at the apex. Spikelets linear, or oblong; laterally compressed; 20-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes terete; springy and forming a hair trap; 1.5-2.5 mm long; eventually visible between lemmas. Floret callus elongated; pubescent; obtuse.
    Fertile
    Spikelets comprising 2-4 fertile florets; with diminished florets at the apex. Spikelets linear, or oblong; laterally compressed; 20-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes terete; springy and forming a hair trap; 1.5-2.5 mm long; eventually visible between lemmas. Floret callus elongated; pubescent; obtuse.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 3-10 mm long; 0.2-0.5 length of upper glume; scarious; dark brown; 1-keeled; 3 -veined. Lower glume apex acute. Upper glume lanceolate; 17-23 mm long; 1 length of adjacent fertile lemma; scarious; dark brown; 1-keeled; 17 -veined. Upper glume lateral veins with cross-veins. Upper glume apex acute; mucronate.
    Florets
    Fertile lemma oblong; subterete; 18-22 mm long; coriaceous; dark brown; without keel; 9 -veined. Lemma surface pilose; hairy below. Lemma margins convolute; covering most of palea. Lemma apex dentate; truncate; awned; 1 -awned. Principal lemma awn from a sinus; 15-25 mm long overall; limb scaberulous. Palea keels contiguous above a sulcus. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 3; oblanceolate; 1.5-2.5 mm long; membranous; veined; ciliate; obtuse. Anthers 2. Stigmas 2; terminally exserted and tangled; retrorsely barbellate. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp; linear; isodiametric; biconvex; 15 mm long; hairy at apex; apex rostrate. Embryo 0.1 length of caryopsis. Hilum linear; 1 length of caryopsis.
    Distribution
    Africa: west tropical, west-central tropical, northeast tropical, and east tropical. Asia-tropical: India.

    Gramineae, W. D. Clayton. Flora of West Tropical Africa 3:2. 1972

    Habit
    A broad-leaved perennial of forest shade, 0·3–1·7 in. high spreading by scaly rhizomes.
    Inflorescences
    The rhachilla segment adjacent to the base of each lemma forms a trap for catching hairs and thus effecting dispersal.

    Habit
    Culms 30–150 cm. high, arising from scaly rhizomes.
    Leaves

    Inflorescences
    Raceme 11–30 cm. long, the spikelets imbricate and borne upon short pedicels 1–2 mm. long.
    Spikelets
    Spikelets 22–30 mm. long, dark green to brown; lower glume 3–10 mm. long; upper glume 17–23 mm. long; fertile lemmas narrowly oblong-lanceolate, 18–22 mm. long, appressedly pubescent below, and narrowed into a shortly bearded subacute callus 1.5–2.5 mm. long; awn scaberulous, up to 25 mm. long; stigmas 2, 1–2 cm. long, retrorsely spinulose; ovary pilose above.
