    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; bilateral; 6-15 cm long. Rhachis semiterete; puberulous on surface. Spikelet packing broadside to rhachis. Rhachis internodes linear. Rhachis internode tip flat. Spikelets appressed; solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 3-12 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 10-22 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes scaberulous.
    Fertile
    Spikelets comprising 3-12 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 10-22 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes scaberulous.
    Glume

Lower glume apex acute. Upper glume lanceolate; 6.5-7 mm long; 0.8 length of adjacent fertile lemma; coriaceous; with scarious margins; without keels; 3-5 -veined. Upper glume apex acute.
    Florets
    Fertile lemma lanceolate; 8 mm long; chartaceous; 5 -veined. Lemma midvein scaberulous. Lemma margins clavately ciliolate. Lemma apex acute; muticous. Palea 0.75 length of lemma. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.
