    Habit
    Perennial. Stolons present. Culms erect; 60-100 cm long; wiry. Lateral branches sparse. Ligule a fringe of hairs. Leaf-blades stiff.
    Inflorescences
    Inflorescence composed of racemes. Racemes borne along a central axis; erect; unilateral; bearing few fertile spikelets; bearing 3-7 fertile spikelets on each. Rhachis angular. Spikelet packing broadside to rhachis; lax. Spikelets ascending; solitary. Fertile spikelets pedicelled. Pedicels linear.
    Spikelets
    Spikelets comprising 8-25 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; 12-26 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes villous. Floret callus bearded.
    Fertile
    Spikelets comprising 8-25 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; 12-26 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes villous. Floret callus bearded.
    Glume
    Glumes persistent; shorter than spikelet. Lower glume lanceolate; 0.9-1 length of upper glume; coriaceous; without keels; 3-5 -veined. Lower glume apex acute. Upper glume lanceolate; 0.9-1 length of adjacent fertile lemma; coriaceous; without keels; 5-7 -veined. Upper glume apex acute.
    Florets
    Fertile lemma lanceolate; coriaceous; without keel, or keeled; 3 -veined. Lemma surface asperulous. Lemma apex entire, or dentate; 2 -fid; incised 0.05 of lemma length; obtuse, or acute; mucronate. Palea 1 length of lemma; hyaline; 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; fleshy. Anthers 3. Stigmas 2.
    Fruits
    Caryopsis with adherent pericarp; ellipsoid; dorsally compressed; concavo-convex. Embryo 0.4 length of caryopsis. Hilum punctiform.

    Habit
    Perennial
    Leaves
    Leaf-blades narrow; ligule a ciliate rim
    Inflorescences
    Inflorescence of racemes scattered along a central axis, the spikelets shortly pedicelled
    Spikelets
    Spikelets laterally compressed, disarticulating between the florets, awnless, the short rhachilla-internodes bearded at the apex with long hairs up to 1/2 the length of the lemma; glumes persistent, subequal, the lower 3–5-nerved, the upper 5–7-nerved; lemmas exserted from the glumes, coriaceous, rounded on the back or keeled only above the middle, acute or slightly obtuse, entire, shortly mucronate; palea as long as the lemma
    Fruits
    Caryopsis elliptic to elliptic-oblong, concavo-convex in section.

    Gramineae, T. Cope. Flora Zambesiaca 10:2. 1999

    Habit
    Inflorescence of short racemes scattered along and appressed to an elongated central axis.
    Spikelets
    Spikelets several-flowered, shortly pedicelled, laterally compressed, disarticulating above the glumes and between the florets, the callus conspicuously barbate with hairs c. 1/2 the length of the lemma; glumes persistent, subequal, the inferior 3–5-nerved, the superior 5–7-nerved; lemmas exserted from the glumes, 3-nerved, coriaceous, dorsally rounded or keeled only above the middle, acute or subobtuse at the apex, entire or bidenticulate, shortly mucronate.
