Rhachis internodes cuneate. Rhachis internode tip oblique; cupuliform. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels cuneate; flattened; 2 mm long; ciliate; tip cupuliform; toothed.
    Sterile
    Basal sterile spikelets well-developed; 4-6 in number; barren; elliptic; 8-9 mm long; larger than fertile. Basal sterile spikelet glumes chartaceous (winged). Companion sterile spikelets well-developed; containing empty lemmas; elliptic; asymmetrical; dorsally compressed; 10 mm long; longer than fertile; deciduous with the fertile. Companion sterile spikelet glumes chartaceous; winged on margins; distinctly veined; acute. Companion sterile spikelet lemmas 1; enclosed by glumes.
