Granadilla , (Span., diminutive of granada, a pomegranate), the Spanish-American name for the edible fruit of several species of passi-flora, especially that of P. quadrangularis. The genus passiflora, which will be described under Passion Flower, is well known for the great beauty of the flowers of many species which are common greenhouse climbers. Other edible-fruited species are P. edulis, P. lau-rifolia (the water lemon), P. maliformis (the sweet calabash), and P. incarnata, the may-pop of the southern states. P. quadrangu-laris is a native of the West Indies, where its fruit is esteemed for the dessert. In French works upon horticulture it is placed among the exotic fruits to be grown under glass, and granadillas thus produced are sometimes seen in the markets of Paris and London. In our greenhouses the plant is often seen in flower, but rarely in fruit, as gardeners do not seem to be aware that the flowers require to be artificially fertilized with their own pollen or that of some other species, else the fruit will not set. The fruit is 6 or 8 in. in diameter, of a mulberry color, and with an odor something like the pineapple or strawberry. The purple pulp, which encloses numerous seeds, is subacid, and is usually eaten with wine and sugar.

In contrast with the fruit, the root of this species is powerfully narcotic and emetic.
