Eichhornia

Species of plant

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, 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
