passion-fruit the best known of the fruits of various species of the genus Passiflora. This is a large group of climbing herbs and shrubs native to tropical America, SE Asia, and Australia. The names granadilla (or grenadilla) and water lemon are also used of the fruits of this group, overlapping with the name passion-fruit in a way which necessitates treating them all together. Granadilla is derived from granada, Spanish for pomegranate, and means ‘small pomegranate’. Maracuya is the name generally used in Brazil.
