The mangosteen is a species of evergreen tree in the Clusiaceae family, native to Southeast Asia, but now cultivated in several other tropical areas. It is cultivated for its edible fruit, the purple mangosteen. It is the most widely cultivated species within the Garcinia genus, though many other species also produce fruit and are grown for local consumption. The mangosteen is closely related to the gamboge trees (G. hanburyi and G. morella, both native to India), whose resin is used to make the yellow pigment of the same name. Gamboge is famous as the dye used to color the robes of Buddhist monks.
