    Inflorescences
    Inflorescence a panicle. Panicle open; oblong; 9-11 cm long; 2-5 cm wide. Primary panicle branches spreading; whorled at most nodes. Panicle branches eglandular, or glandular (glands less than 0.5mm diam); smooth, or scaberulous. Spikelets appressed; solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; (1.5-)1.7-2(-2.4) mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile

Lower glume linear; 0.7 mm long; 0.33-0.5 length of upper glume; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 1.5-2.4 mm long; 0.9-1.2 length of adjacent fertile lemma; membranous; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.
    Florets
    Fertile lemma lanceolate; 1.7-2 mm long; membranous; without keel; 1 -veined. Lemma apex acute. Palea 1 length of lemma; 2 -veined. Palea keels approximate.
