Garcinia prainiana

Garcinia prainiana, known as the button mangosteen or cherapu, is a species of flowering plant in the family Clusiaceae. Its fruit has a flavor similar to its cousin, the purple mangosteen, with an interesting taste some have compared to a tangerine, but unlike its cousin it has a tissue-thin skin rather than a hard rind, making it much easier to eat out-of-hand. Also unlike the purple mangosteen, it can be grown in a container. The fruit is cultivated widely in Southeast Asia. In the United States, success has been found with its cultivation by a few backyard growers in South Florida and the Whitman Tropical Fruit Pavilion at Florida's Fairchild [Tropical Botanic Garden].
It is a native of Malaysia and Thailand. The tree is small or medium-sized. It was featured in Malaysian 30 cents stamp in 1999.
