is a species of tropical American tree which produces tasty fruit. In English it is known as the lemon drop mangosteen (a name it shares with the closely related and similarly tasting Garcinia madruno). In Spanish it is called mameyito, though it is known as jorco in Costa Rica. In the Philippines, it is known as berba. In Portuguese it is called achachairu. The name achachairu is also applied to Garcinia humilis, another species native to Bolivia with larger, round or egg-shaped fruit. It has been commercialized in Austrlia under the name Achacha.
The fast-growing tree reaches a height of about 5 meters. It is tolerant of a wide range of soils, up to an altitude of around 4000 feet. It can be grown successfully and will fruit in a large pot. It grows best with regular water in full sun in a humid environment. It tolerates high temperatures but is probably not frost hardy. It has small, whitish flowers which are perfect and makes an attractive ornamental tree, especially when in fruit, which may be year round. Its leaves are opposite.
The wood is termite resistant and used to make posts and tool handles.
The tree may fruit after as little as two years. The fruits are smooth spheres about an inch in diameter with a thin yellow, orange or red rind around a white pulp. They are edible and have an appealing sweet and sour taste. It is usually eaten out of hand, though can be used for drinks, jams and jellies.
