Nymphaea
Nymphaea , proper noun
[Latin, the water lily, Greek {not transcribed}.]
(Botany) A genus of aquatic plants having showy flowers (white, blue, pink, or yellow, often fragrant), including the white water lily and the Egyptia lotus.
Recent critics have endeavored to show that this genus should be called Castalia, and the name Nymphaea transferred to what is now known as Nuphar.
