Nymphæa
Nym·phæ′a, n. [L., the water lily, Gr. νυμφαία.] (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.
☞ Recent critics have endeavored to show that this genus should be called Castalia, and the name Nymphæa transferred to what is now known as Nuphar.
