HABIT Perennial. Stolons present. Culms decumbent; 10–90 cm long. Ligule a ciliate membrane.
INFLORESCENCE Inflorescence composed of racemes.
Racemes digitate; unilateral. Rhachis deciduous from axis; angular. Spikelet packing broadside to rhachis; crowded.
Spikelets appressed; solitary. Fertile spikelets sessile.
FERTILE SPIKELETS Spikelets comprising 4–8 fertile florets; with diminished florets at the apex. Spikelets elliptic, or oblong; laterally compressed; breaking up at maturity; disarticulating above glumes but not between florets. Rhachilla internodes definite.
GLUMES Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume oblong; 0.5 length of upper glume; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface without pits. Lower glume apex acute. Upper glume oblong; 0.7 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acute.
FLORETS Fertile lemma ovate; chartaceous; keeled; wingless; 3 -veined. Lemma surface unwrinkled; without grooves; glabrous, or pilose. Lemma margins pubescent. Lemma apex acute; muticous, or mucronate. Palea keels ciliate. Apical sterile florets resembling fertile though underdeveloped.
FRUIT Caryopsis with free soft pericarp.
DISTRIBUTION Africa, or Temperate Asia, or Tropical Asia.
