Spikelets oblong; laterally compressed; 12-16 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes elongated below proximal fertile floret. Rhachilla elongation 1.5-2 mm long; pilose (hairs 5-7mm). Floret callus pilose.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; 12-16 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes elongated below proximal fertile floret. Rhachilla elongation 1.5-2 mm long; pilose (hairs 5-7mm). Floret callus pilose.
    Glume

Lower glume lanceolate; 6.5-9 mm long; 0.5-0.66 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume lanceolate; 12-13.5 mm long; 1.2 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acuminate.

Lemma of lower sterile floret elliptic; 13-15 mm long; chartaceous; much thinner above; 7 -veined; villous; dentate; 2 -fid; setaceously attenuate (lateral awns 1-2.5mm); awned. Awn of lower sterile floret dorsal; arising 0.1 way up back of lemma; geniculate; 25-40 mm long. Fertile lemma elliptic; 9-10 mm long; chartaceous; much thinner above; without keel; 7 -veined. Lemma surface villous. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn subapical; 10-16 mm long overall. Palea keels ciliolate.
