Additional comments

Victoria is by far one of the largest and most spectacular aquatic plants. Mature leaf blades are large and buoyant enough to support the weight of a human. Two species are known: V. amazonica tends to have larger, redder leaves with rather low rims, while V. cruziana is greener, with higher rims.
