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). INFLORESCENCE 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. FERTILE 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. GLUMES 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. FLOWER Lodicules 2; fleshy. Anthers 3 (1/1). FRUIT 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).
