    Habit
    Stiff spiny rhizomatous perennials, the glaucous shoots with numerous distichous pungent leaves; culms branched or not, leafy for all or most of their length
    Leaves
    Leaf-blades short and tough, many-ribbed, inrolled from a flat base, smooth or hairy; ligule a fringe of hairs; leaf-sheaths imbricate
    Inflorescences
    Inflorescence dense and spike-like, narrowly elliptic to almost globose, composed of short crowded subsecund racemes
    Spikelets
    Spikelets several-flowered, elliptic to narrowly elliptic, imbricate, shortly pedicelled, disarticulating between the florets; glumes 1-nerved, persistent, shorter than the lemmas, subequal to unequal, rounded or subkeeled, scarious, obtuse or acute; lemmas 3-nerved, rounded on the back, scarious or membranous with scarious margins, silky villous along the lateral nerves and lower part of the central nerve, the hairs spreading, minutely 2-toothed and mucronate; palea scabrid on the keels and appressed sericeous on the inturned margins; callus bearded.

    Habit
    Inflorescence dense and spike-like, narrowly elliptic to almost globose, composed of short crowded subsecund racemes.
    Spikelets
    Spikelets several-flowered, imbricate, shortly pedicelled, disarticulating above the glumes and between the florets, slightly laterally compressed; glumes 1-nerved, persistent, shorter than the lemmas, subequal to unequal, dorsally rounded or lightly keeled, scarious, obtuse or acute; lemmas 3-nerved, dorsally rounded, scarious or membranous with scarious margins, silky-villous along the lateral nerves and the lower part of the central nerve, the hairs spreading, minutely 2-toothed at the apex and mucronate.
    Fruits
    Caryopsis elliptic, with free pericarp.

    nonem

    Habit
    Perennial. Rhizomes elongated. Culms geniculately ascending; 15-65.5-200 cm long. Lateral branches lacking (1), or suffrutescent (1). Ligule a fringe of hairs. Leaf-blades coriaceous; stiff. Leaf-blade apex pungent.
    Inflorescences
    Inflorescence composed of racemes. Racemes borne along a central axis; in a multilateral false spike (1), or in a head; unilateral; bearing few fertile spikelets; bearing 3-14 fertile spikelets on each (1/1). Rhachis subterete. Spikelet packing broadside to rhachis; crowded. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.
    Spikelets
    Spikelets comprising 4-9 fertile florets, or 10 fertile florets (1); with diminished florets at the apex. Spikelets elliptic; laterally compressed; 5-7.5-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pilose.
    Fertile
    Spikelets comprising 4-9 fertile florets, or 10 fertile florets (1); with diminished florets at the apex. Spikelets elliptic; laterally compressed; 5-7.5-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pilose.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 0.6-0.65-0.7 length of upper glume; scarious; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume oblong; 0.6-0.9-1.2 length of adjacent fertile lemma; scarious; without keels; 1 -veined. Upper glume surface smooth (1), or scabrous (1). Upper glume apex obtuse.
    Florets
    Fertile lemma ovate; membranous; without keel; 3 -veined. Lemma midvein ciliate. Lemma margins ciliate. Lemma apex dentate; 2 -fid; mucronate. Palea 1 length of lemma; 2 -veined. Palea keels scaberulous. Palea surface pubescent. Apical sterile florets resembling fertile though underdeveloped.
    Fruits
    Caryopsis with free soft pericarp; ellipsoid.
    Distribution
    Africa, or Temperate Asia (1).
