Isolepis fluitans (syn. Scirpus fluitans), the floating scirpus, is a species of flowering plant in the sedge family. It is native to Africa, Australasia, Europe, and the Pacific islands.[1] It was first described by Carl Linnaeus in 1753, and later transferred to Isolepis by the botanist Robert Brown in 1810.
The species epithet fluitans is Latin for floating.[2]
