Euryale nodulosa is a fossil species of Euryale from the Pliocene of Reuver, Limburg Province, Netherlands and Italy.
It is an aquatic herb with globose, 8mm long, and 8 mm wide seeds. The testa has nodules.
It was first published as Euryale nodulosa by Clement Reid and Eleanor Mary Reid in 1915. It has been proposed to place it in a separate genus Pseudoeuryale as Pseudoeuryale nodulosa published by Andrei Grigorievich Negru in 1979. It has also been viewed as a synonym of Euryale europaea by Kirchheimer, which was rejected by Martinetto.
It occurred in the Netherlands, and in Italy.
