Photo of a young Passion Fruit. The scientific name of Passion Fruit is Passiflora edulis. It is also known as "Markisa" in Bahasa Melayu (Malay language). The Passion fruit is so called because it is one of the many species of Passion Flower. ("Passion Flower" being the literal English translation of the Latin genus name, Passiflora). The name was given by missionaries because the parts of the flower seemed reminiscent of the torture (the Passion) of Christ prior to his crucifixion.
