Taxonomy
It was first collected in 1921 by Charles Gardner, but it was not then seen to be a new species.[5] It was first published as Ondinea purpurea Hartog by Cornelis den Hartog in 1970.[1] 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 (the option of retaining the same epithet, as Nymphaea purpurea, was not available, as this combination had been used before for another species).[1][6] The type specimen was collected by W. Leutert North-East of Kalimburu, Kimberley district, Western Australia on the 15th of April 1968.[7][8] It is placed in Nymphaea subg. Anecphya.[6]
Etymology
The species name ondinea is derived from the name of the water nymph in the 1958 ballet Ondine.[5]
