Pedicels 9-25 mm long.  Spikelets comprising 8-15 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 5-12 mm long; 2 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes obscured by lemmas.  Glumes deciduous; similar; shorter than spikelet. Lower glume lanceolate; 1 mm long; 0.66 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 1.5 mm long; 0.75 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.  Florets: Fertile lemma ovate; 2 mm long; membranous; keeled; 3 -veined. Lemma lateral veins distinct. Lemma apex acute.
