A vertical, end view, and cross-section of a
carambola, the fruit of
Averrhoa carambola, a species of tree native to Southeast Asia and South Pacific islands. The fruit has ridges running down its sides (usually five, but the number may vary); in cross-section, it resembles a star, inspiring the alternative name
starfruit. The entire fruit, including the slightly waxy skin, is edible.
