    Habit
    Perennial. Culms erect; slender (1/1); 20-40.33-60 cm long; firm (5), or wiry (1). Lateral branches lacking. Leaves differentiated into sheath and blade (3), or without demarcation between sheath and blade (3). Ligule a ciliolate membrane (4), or a ciliate membrane (1), or a fringe of hairs (1). Leaf-blades filiform (5), or linear (1); herbaceous (5), or coriaceous (1); stiff (1), or firm (5). Leaf-blade margins cartilaginous (1/1).
    Inflorescences
    Inflorescence composed of racemes. Racemes single; erect; unilateral; bearing 7-35 fertile spikelets on each (1/1). Rhachis angular. Spikelet packing broadside to rhachis; crowded (2), or contiguous (3), or distant (1); 2 -rowed (5/5). Spikelets ascending (5/5); solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 7-8 fertile florets (1), or 9 fertile florets (2), or 10 fertile florets (3), or 11 fertile florets (4), or 12-15 fertile florets (5), or 16-19 fertile florets (2), or 20-50 fertile florets (1); with diminished florets at the apex. Spikelets elliptic (5), or oblong; laterally compressed; 5-9.416-20 mm long; breaking up at maturity; rhachilla persistent; retaining paleas.
    Fertile
    Spikelets comprising 7-8 fertile florets (1), or 9 fertile florets (2), or 10 fertile florets (3), or 11 fertile florets (4), or 12-15 fertile florets (5), or 16-19 fertile florets (2), or 20-50 fertile florets (1); with diminished florets at the apex. Spikelets elliptic (5), or oblong; laterally compressed; 5-9.416-20 mm long; breaking up at maturity; rhachilla persistent; retaining paleas.
    Glume
    Glumes lower persistent, upper deciduous (4/5), or deciduous (1/5); shorter than spikelet. Lower glume lanceolate, or ovate (5); 0.66-0.8933-1.5 length of upper glume; membranous (5), or cartilaginous (1); 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse (1), or acute (5), or acuminate (2). Upper glume lanceolate (1), or oblong (5), or ovate (5); 0.7-0.95-1.5 length of adjacent fertile lemma; membranous (5), or cartilaginous (1); without keels (1), or 1-keeled (5); 1 -veined. Upper glume apex obtuse (2), or acute (3), or acuminate (1).
    Florets
    Fertile lemma lanceolate (1), or ovate (5); chartaceous (1), or cartilaginous (5); keeled; 3 -veined. Lemma midvein without distinctive roughness (5), or scaberulous (1). Lemma apex truncate (1), or obtuse (2), or acute (2), or acuminate (1); without ornament (5), or scabrous (1), or pubescent (1). Palea 0.8-0.9125-1 length of lemma; 2 -veined. Palea keels winged; eciliate (2), or ciliolate (4). Palea surface glabrous (5), or pubescent (1). Palea apex entire (1/1). Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; fleshy. Anthers 3 (1/1).
    Fruits
    Caryopsis with adherent pericarp; ellipsoid (1/2), or ovoid (1/2); isodiametric (5/5); trigonous (1/1). Embryo 0.3-0.35-0.4 length of caryopsis.
    Distribution
    Africa (1), or Temperate Asia (1), or Tropical Asia (5), or Australasia (1).

    Habit
    Slender densely tufted perennials with erect unbranched culms
    Leaves
    Leaf-blades mainly basal, usually filiform; ligule a narrow ciliate membrane
    Inflorescences
    Inflorescence a solitary terminal subsecund spike of biseriate imbricate spikelets
    Spikelets
    Spikelets many-flowered, with tightly imbricate florets, narrow, often linear-oblong, laterally compressed, the lemmas disarticulating irregularly at maturity leaving the paleas on the rhachilla, sometimes also the rhachilla fracturing and the upper part of the spikelet falling away; glumes unequal, cartilaginous, shorter than the lemmas, the lower 1-nerved, the upper 1–3-nerved; lemmas 3-nerved with the lateral nerves ± 3/4 as long as the lemma, keeled, lanceolate to ovate in profile, cartilaginous, glabrous, acute to emarginate; palea narrowly to broadly winged on the keels, smooth or ciliolate along the wing margins
    Fruits
    Caryopsis small, plump, light brown.
