Utricularia tetraloba

A very small, probably perennial bladderwort that grows as a rheophyte, clinging to rocks in shallow running water in Guinea and Sierra Leone. It belongs to the small section Avesicarioides, and differs from its relative U. rigida in having four lobes on the lower lip of the corolla. It is listed as Vulnerable and is essentially unknown in cultivation, so everything below about growing it is extrapolated from its habitat.
