Nym·phae·a prop. n.  Bot. A genus of aquatic plants having showy flowers (white, blue, pink, or yellow, often fragrant), including the white water lily and the Egyptia lotus.
  Note: ☞ 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.
