    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 6-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume

Lemma of lower sterile floret elliptic; 5-6.5 mm long; chartaceous; 1-keeled; 5 -veined; ciliolate on margins; obtuse; mucronate. Lemma of upper sterile floret oblong; 1 length of lower sterile floret; chartaceous; ciliolate on margins; obtuse; awned. Awn of upper sterile floret dorsal; arising 0.75 way up back of lemma; geniculate; 1.5-4 mm long. Fertile florets female. Fertile lemma ovate; 4-4.5 mm long; cartilaginous; without keel; 5 -veined. Lemma surface scaberulous; rough above. Lemma margins convolute; covering most of palea. Lemma apex acute. Palea linear; 1 -veined; without keels.
