    Inflorescences
    Inflorescence composed of racemes; exserted (2), or embraced at base by subtending leaf (1). Racemes single; erect (1), or drooping (2); unilateral; bearing few fertile spikelets; bearing 2 fertile spikelets on each (1), or 3-4 fertile spikelets on each (2), or 5-7 fertile spikelets on each (1), or 8-9 fertile spikelets on each (2), or 10-11 fertile spikelets on each (1). Rhachis subterete. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Basal sterile spikelets represented by a single scale. Spikelets comprising 1-2 fertile florets (1), or 4-5 fertile florets (1); without rhachilla extension (1), or with diminished florets at the apex (2). Spikelets linear (1), or lanceolate (1), or oblong (1), or cuneate (2); laterally compressed (2), or subterete (1); 10-16.5-22 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pilose (2/2). Floret callus evident; pubescent (2), or bearded (1).
    Sterile
    Basal sterile spikelets represented by a single scale.
    Fertile
    Spikelets comprising 1-2 fertile florets (1), or 4-5 fertile florets (1); without rhachilla extension (1), or with diminished florets at the apex (2). Spikelets linear (1), or lanceolate (1), or oblong (1), or cuneate (2); laterally compressed (2), or subterete (1); 10-16.5-22 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pilose (2/2). Floret callus evident; pubescent (2), or bearded (1).
    Glume
    Glumes persistent; reaching apex of florets (2), or exceeding apex of florets (1); parallel to lemmas (1), or gaping (2). Lower glume elliptic; 0.9-0.9833-1 length of upper glume; herbaceous; 1-keeled; 5 -veined (2), or 6 -veined (1), or 9 -veined (1). Lower glume surface smooth (1), or asperulous (2). Lower glume apex acute. Upper glume elliptic; 1-1.066-1.1 length of adjacent fertile lemma; herbaceous; with hyaline margins; 1-keeled; 6-7 -veined (1), or 8-9 -veined (2), or 10 -veined (1). Upper glume surface smooth (1), or asperulous (2). Upper glume apex acute.
    Florets
    Fertile lemma elliptic (1), or oblong (2); membranous; much thinner on margins; without keel; 7 -veined (1), or 9-11 -veined (1). Lemma surface smooth (1), or scaberulous (2); glabrous (1), or villous (2); without hair tufts (2), or with a transverse fringe of hair (1). Lemma apex dentate (1), or lobed (2); 2 -fid; incised 0.2-0.35-0.5 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate. Palea 2 -veined. Palea keels scabrous. Palea surface glabrous (1), or pilose (2). Palea apex muticous (1), or with excurrent keel veins (2). Apical sterile florets resembling fertile though underdeveloped (2/2).
