Nymphaea \Nym*phae"a\, prop. n. [L., the water lily, Gr. ?.]
   (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.
   [1913 Webster]

   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}.
