Passiflora maliformis
 Passiflora maliformis (sweet calabash conch apple wild purple passionfruit or sweet cup) is a smallish (2) passionfruit with purple yellow or green skin and a grayed-yellow orange pulp that is aromatically scented and flavored. It is a fast growing vine growing best in somewhat cooler than tropical climates. The rind is particularly hard and tougher than most passion fruits. It is usually grown from seeds but may also be propagated by stem-cuttings.
