Eichhornia
Species of plant / From Wikipedia, the free encyclopedia
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. 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.
It was named in honour of Friedrich Eichhorn [de], an early-19th-century Prussian minister of education.[2]
