General Description

HABIT Annual. Culms erect (1/1), or geniculately ascending (1/1); 15-65.83-120 cm long. Ligule an eciliate membrane (1), or a ciliolate membrane. INFLORESCENCE Inflorescence composed of racemes. Racemes borne along a central axis; spreading, or deflexed (2); linear, or oblong (1), or cuneate (1); unilateral; bearing few fertile spikelets (1), or many spikelets; bearing 2-20 fertile spikelets on each (1/1). Rhachis persistent (2), or deciduous from axis (1); wingless (2), or narrowly winged (1); flattened (1/2), or angular (1/2). Spikelet packing broadside to rhachis. Spikelets appressed; solitary. Fertile spikelets sessile. FERTILE SPIKELETS Spikelets comprising 1 fertile florets (1), or 2 fertile florets, or 3 fertile florets (2), or 4 fertile florets (1); with diminished florets at the apex. Spikelets lanceolate (1), or cuneate (2); laterally compressed; 3.2-5.233-9 mm long; breaking up at maturity; disarticulating below each fertile floret. GLUMES Glumes persistent; exceeding apex of florets; firmer than fertile lemma; parallel to lemmas (2), or recurved at apex (1). Lower glume lanceolate (2), or elliptic (1); 0.9-0.9667-1 length of upper glume; membranous (1), or coriaceous (2); 1-keeled; 1 -veined, or 2-3 -veined (1). Lower glume lateral veins absent (2), or distinct (1). Lower glume apex acute (1), or attenuate (1), or caudate (1). Upper glume lanceolate (2), or elliptic (1); 1.5-2.583-3 length of adjacent fertile lemma; membranous (1), or coriaceous (2); 1-keeled; 1 -veined (2), or 3 -veined (1). Upper glume apex acute (1), or attenuate (1), or caudate (1). FLORETS Fertile lemma ovate; membranous; keeled; 3 -veined. Lemma midvein pubescent. Lemma margins pubescent. Lemma apex entire (2), or dentate (1); 2 -fid (1/1); emarginate (1/2), or obtuse (1/2), or acute (1/2); muticous (1), or mucronate (2). Palea 0.8-0.85-0.9 length of lemma; 2 -veined. Palea keels eciliate (1), or pubescent (2). Apical sterile florets resembling fertile though underdeveloped. FRUIT Caryopsis with adherent pericarp; ellipsoid (2/2); isodiametric (2/2); trigonous (2/2). DISTRIBUTION Africa, or Temperate Asia (1), or Tropical Asia (1), or Australasia (1).
