    Habit
    Perennials
    Leaves
    Leaf-blades flat, narrow; ligule a line of hairs
    Inflorescences
    Inflorescence a loose many-sided false raceme, the spikelets solitary or paired and falling together with the enlarged common peduncle
    Spikelets
    Spikelets linear to lanceolate, awnless; glumes well developed, dissimilar, smooth or tuberculate-spinulose, the lower glume (only one of them when spikelets paired) modified into a long flat recurved tail, the upper glume tightly enfolding the floret; lemma broadly ovate, shorter than the glumes, hyaline, 1-nerved; palea tiny, up to 1/2 as long as the lemma, linear, hyaline; stamens 3
    Fruits
    Caryopsis subterete to ellipsoid, slightly laterally compressed.

    Habit
    Perennial. Culms geniculately ascending; 10-33.75-60 cm long; wiry. Leaf-sheath auricles absent (1), or erect (1). Ligule a fringe of hairs. Leaf-blades linear, or lanceolate (1).
    Inflorescences
    Inflorescence composed of racemes. Racemes borne along a central axis; in a multilateral false spike; spreading; cuneate; bearing few fertile spikelets; bearing 1 fertile spikelets on each (1), or 2 fertile spikelets on each. Rhachis obsolete; deciduous from axis. Raceme-bases cuneate. Spikelets solitary (1), or in pairs. Fertile spikelets sessile; 1 in the cluster (1), or 2 in the cluster; subequal, or the upper smaller.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets linear, or lanceolate; laterally compressed; symmetrical (1), or gibbous (1); 2.5-5.875-8 mm long; falling entire; deciduous with accessory branch structures.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets linear, or lanceolate; laterally compressed; symmetrical (1), or gibbous (1); 2.5-5.875-8 mm long; falling entire; deciduous with accessory branch structures.
    Glume
    Glumes exceeding apex of florets; firmer than fertile lemma; parallel to lemmas (1), or recurved at apex (1). Lower glume linear (1), or lanceolate; 1-1.325-2 length of upper glume; coriaceous; without keels; 1-3 -veined. Lower glume surface convex, or flat; smooth, or scabrous (1), or tuberculate (1). Lower glume apex acute (1), or attenuate (1), or setaceously attenuate (1), or cuspidate (1), or rostrate (1), or caudate. Upper glume linear (1), or lanceolate (1), or oblong (1); not gibbous (1), or gibbous (1); 2-3.25-4 length of adjacent fertile lemma; coriaceous; without keels; 3 -veined. Upper glume primary vein ciliate. Upper glume surface scabrous (1), or tuberculate (1). Upper glume apex acuminate (1), or caudate.
    Florets
    Fertile lemma ovate; hyaline; without keel; 1 -veined. Lemma margins ciliolate. Lemma apex obtuse (1), or acute (1). Palea 0.3-0.55-0.8 length of lemma; hyaline; 0 -veined; without keels (1), or 2-keeled (1).
    Flowers
    Anthers 3.
    Fruits
    Caryopsis with adherent pericarp; fusiform (1), or ellipsoid (1); laterally compressed; biconvex. Embryo 0.5 length of caryopsis.
    Distribution
    Africa (1), or Temperate Asia (1), or Tropical Asia (1), or South America (1).
