Rhachis deciduous from axis; angular. Spikelet packing broadside to rhachis; crowded. Spikelets ascending; solitary. Fertile spikelets pedicelled. Pedicels oblong; 0.8-1.6 mm long.
    Spikelets
    Spikelets comprising 5-6 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 5-8 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent; hairy at tip.
    Fertile
    Spikelets comprising 5-6 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 5-8 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent; hairy at tip.

Lemma apex attenuate; awned; 1 -awned. Principal lemma awn 2 mm long overall. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
