The submerged leaves with undulate leaf margins[1] are 6–24 cm long. The upper surface of the submerged leaves is green, and the lower surface is dark blue. The floating leaves are 7 cm long, and 2 cm wide.

Taxonomy

It was first published as Ondinea purpurea Hartog by Hartog in 1970. It was transferred to the genus Nymphaea L. as Nymphaea ondinea Löhne, Wiersema & Borsch published by Cornelia Löhne, John Harry Wiersema, and Thomas Borsch in 2009.[3] The type specimen was collected by W. Leutert North-East of Kalimburu, Kimberley district, Western Australia on the 15th of April 1968.[4] [5] It is placed in Nymphaea subg. Anecphya.
