Nymphaea mexicana is a species of aquatic plant that is native to the Southern United States and Mexico as far south as Michoacán.

[5] The floating or emersed,[5] yellow, 6–13 cm wide flowers have peduncles with 4 primary air canals.

Their structure, resembling bananas, consists of leaf buds and thick, starchy roots.

[1] It occurs in up to 4 m deep water[18] in lagoons, canals[19] swamps, and rivers.

[19] The canvasback duck, Aythya valisineria, feeds on the banana-like roots of the plant.
