Nymphaea oxypetala is a species of waterlily native to Bolivia, Brazil, Cuba, Ecuador, Paraguay, and Venezuela.

The purplish-green, submerged, saggitate, membranous leaves are significantly larger with up to 30 cm big leaf blades.

[12] In the Pantanal it occurs in the flooding area of the Paraguay River, Nabileque, Abobral and Poconé.

[4] In the Bolivian Pantanal, Nymphaea oxypetala was observed growing at depths of up to 2 m in gaps amid mats of floating vegetation and in localities where human activities prevented the growth of such floating mats along the margins.

[14] It is intolerant of cold, turbid and saline water and favours clear, slowly flowing freshwater.
