Eichhornia, commonly called water hyacinths, was a polyphyletic genus of the aquatic flowering plants family Pontederiaceae. Since it was consistently recovered in three independent lineages, it has been sunk into Pontederia, together with Monochoria. Each of the three lineages is currently recognized as subgenera in Pontederia: Pontederia subg. Cabanisia, which includes P. meyeri, P. paniculata (the Brazilian water hyacinth), and P. paradoxa Pontederia subg. Oshunae, which includes the common water hyacinth, P. crassipes Pontederia subg. Eichhornia, which includes P. azurea, P. diversifoli

Eichhornia, which includes P. azurea, P. diversifolia, P. heterosperma, and P. natans
Pontederia subg. Eichhornia is pantropical, centered in South America but with P. natans being endemic to continental Africa and Madagascar. The other three species are restricted to the Neotropics.
