The mangosteen (Garcinia mangostana) is a tropical evergreen tree with edible fruit native to Maritime Southeast Asia, from the Malay Peninsula to Borneo. It is grown mainly in Southeast Asia, southwest India, and other tropical areas such as Colombia, Puerto Rico and Florida, where the tree has been introduced. The fruit is sweet and tangy, juicy, somewhat fibrous, with fluid-filled vesicles (like the flesh of citrus fruits), with an inedible, deep reddish-purple colored rind (exocarp) when ripe. In each fruit, the fragrant edible white flesh that surrounds each seed is the endocarp, the inner layer of the ovary, and is roughly the same shape and size as a tangerine, about 4 to 6 centimetres (1.5 to 2.5 inches) in diameter. This photograph, which was focus-stacked from 22 individual images, shows two mangosteens, one whole, and the other halved to expose the endocarp.Photograph credit: Ivar Leidus
