    Inflorescences
    Inflorescence a panicle, or composed of racemes (1). Panicle open (3), or contracted (1). Racemes single (1/1). Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform (2/3), or linear (1/3).
    Spikelets
    Spikelets comprising 2-4 fertile florets (1), or 5-6 fertile florets (3), or 7-8 fertile florets, or 9 fertile florets (3), or 10-11 fertile florets (2); with diminished florets at the apex. Spikelets oblong (1), or cuneate (3); laterally compressed; 15-22.5-35 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 2-4 fertile florets (1), or 5-6 fertile florets (3), or 7-8 fertile florets, or 9 fertile florets (3), or 10-11 fertile florets (2); with diminished florets at the apex. Spikelets oblong (1), or cuneate (3); laterally compressed; 15-22.5-35 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet. Lower glume lanceolate; 0.5-0.6625-0.75 length of upper glume; scarious; without keels; 1 -veined, or 2-3 -veined (1). Lower glume lateral veins absent (3), or distinct (1). Lower glume apex acute. Upper glume lanceolate (3), or elliptic (1); 0.75-1.125-1.5 length of adjacent fertile lemma; membranous; without keels; 3 -veined, or 4-5 -veined (1). Upper glume apex acute.
    Florets
    Fertile lemma elliptic (1), or oblong (3); scarious; of similar consistency on margins (1), or much thinner on margins (3); without keel (1), or keeled (3); 5-6 -veined (1), or 7 -veined, or 8-11 -veined (1). Lemma surface smooth (3), or scaberulous (1). Lemma apex emarginate (2), or truncate (2), or obtuse, or acute (1); muticous, or mucronate (1), or awned (1). Principal lemma awn from a sinus (1/1). Palea 0.4-0.5733-0.66 length of lemma; 2 -veined (3/3). Palea keels smooth (1), or scabrous (3). Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Anthers 3. Ovary with a fleshy appendage above style insertion; pubescent on apex (3/3).
