Spikelets acute, 3–3.7 mm long, paired, on unequal pedicels, the longer pedicel c. 3 mm long; lower glume vestigial or apparently lacking; upper glume 5- or 7-nerved, as long as spikelet, margins usually shortly and appressedly ciliate; lower lemma ersembling glume; palea of lower floret vestigial or absent; lemma of upper (bisexual) floret acute, equal to spikelet, dorsally rounded, smooth or minutely striate, brown or purplish at maturity.
