    Inflorescences
    Inflorescence a panicle. Panicle contracted; lanceolate, or oblong; 1.5-5 cm long. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 2-3 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 3.5-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pilose.
    Fertile
    Spikelets comprising 2-3 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 3.5-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pilose.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma; gaping. Lower glume elliptic; 3.5-6 mm long; 1 length of upper glume; membranous; without keels; 3 -veined. Lower glume apex acute. Upper glume elliptic; 3.5-6 mm long; 1.4-1.7 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex acute.
    Florets
    Fertile lemma oblong; 2.5-3.5 mm long; chartaceous; without keel; 9 -veined. Lemma surface pubescent; hairy below; with a transverse row of hair tufts. Lemma margins eciliate. Lemma apex lobed; 2 -fid; incised 0.5 of lemma length; awned; 3 -awned.

Palea 2.2-2.5 mm long. Palea surface pubescent; hairy on back. Apical sterile florets resembling fertile though underdeveloped.
