Racemes paired, not deflexed, 1-1.2 cm long, 2-awned per pair, yellowish green, laterally excerted; bases unequal, the upper 5-7 mm long, glabrous. One pair of homogamous spikelets at the base of the lower raceme, two pairs at the base of the upper raceme.

* Sessile spikelets lanceolate, 6-10 mm long including the pungent callus of 2-3 mm long, callus with short white hairs. Lower glume glabrous, the back rounded or often obscurely hollowed along the median line.
