Păs'sion-flow'er, n.

n. (Bot.) A flower and plant of the genus Passiflora; — so named from a fancied resemblance between its parts and the instruments of our Savior's crucifixion. The flowers are showy, and the fruit sometimes highly esteemed, as that of the granadilla. The roots and leaves are generally more or less noxious, and are used in medicine. But few of the species are found out of South America and the West Indies.
