Spikelets asymmetrical, lanceolate-oblong to ovate, usually laterally or rarely dorsally compressed, plump, florets 2; glumes prominently ribbed, lower glume 1/4–3/4 spikelet length, broad, loose and slightly inflated, upper glume equaling spikelet, deeply concave and gibbous on the back; lower lemma resembling upper glume but less gibbous, staminate or neuter, its palea often much reduced; upper floret readily deciduous, the lemma dorsally compressed, often much shorter than spikelet, thinly coriaceous to cartilaginous, smooth, shiny, margins inrolled or flat but never hyaline. x = 9.

This is a genus of aquatic and marshland grasses, recognized by the spikelike panicle of asymmetrical, ribbed spikelets.

About 30 species: tropics, predominantly in Africa; three species in China.
