    Habit
    Annual. Culms geniculately ascending, or decumbent; 20-90 cm long; rooting from lower nodes. Ligule an eciliate membrane.
    Inflorescences
    Inflorescence a panicle. Panicle open. Spikelets ascending; solitary. Fertile spikelets pedicelled. Pedicels filiform, or linear.
    Spikelets
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 6-8 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent.
    Fertile
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 6-8 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent.
    Glume
    Glumes persistent; shorter than spikelet. Lower glume lanceolate; 0.8-0.9 length of upper glume; membranous; without keels; 3 -veined. Lower glume apex acuminate; mucronate, or awned. Upper glume lanceolate; 1.1-1.3 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acuminate; mucronate, or awned; 1 -awned.
    Florets
    Fertile lemma ovate; membranous; keeled; 3 -veined. Lemma surface pubescent. Lemma apex acute; awned; 1 -awned. Palea 0.5-0.7 length of lemma; 2 -veined. Palea keels ciliate. Palea apex dentate; awned. Apical sterile florets resembling fertile though underdeveloped.

    Habit
    Annual
    Leaves
    Leaf-blades linear; ligule membranous
    Inflorescences
    Inflorescence a panicle, its branches sometimes simple and reduced to racemes
    Spikelets
    Spikelets laterally compressed, disarticulating between the florets; glumes persistent, slightly unequal, 3-nerved, mucronate or short-awned; lemmas shortly exserted from the glumes, membranous, keeled, awned from the entire apex; paleas shorter than the lemmas, the keels ciliate below the middle and both drawn out into a stiff awn
