Primary panicle branches 2-3 cm long; bearing 2-5 fertile spikelets on each lower branch. Panicle axis smooth. Panicle branches capillary; straight, or flexuous; scaberulous. Spikelets solitary. Fertile spikelets pedicelled. Male inflorescence similar to female. Male spikelets resembling female.
    Spikelets
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 7-10 mm long; breaking up at maturity; disarticulating below each fertile floret.

Lemma lateral veins with distinct primaries but obscure intermediates. Lemma surface smooth, or scaberulous; rough on veins. Lemma apex awned; 1 -awned. Principal lemma awn 1 mm long overall. Palea 1 length of lemma; 2 -veined. Apical sterile florets resembling fertile though underdeveloped.
