The single species it comprises, Pistia stratiotes, is often called water cabbage, water lettuce, Nile cabbage, or shellflower.Its native distribution is uncertain, but probably pantropical; it was first discovered from the Nile near Lake Victoria in Africa.istia can be controlled by mechanical harvesters that remove the water lettuce from the water and transport it to disposal on shore. Aquatic herbicides may also be used. Two insects are also being used as a biological control.
