Garcinia intermedia, a little-known fruit tree in the American tropics

Garcinia intermedia (Pittier) Hammel, known as the lemon drop mangosteen in English and by a variety of names including limoncillo and toronjil in Mexico, belongs to the family Clusiaceae, and is distributed in the warm tropical regions of Mexico and Central America at elevations of 300 to 1,000 m. It is an underutilized fruit tree that reaches up to 20 m in height and produces yellow fruits with up to four seeds. The pulp is bittersweet and is highly valued by the rural population of the regions where it grows, where bats and spider monkeys also consume it. The fruit has medicinal properties; it is rich in benzophenones, which attack colon cancer cells. The fruit of G. intermedia has higher antioxidant capacity than the fruit of the mangosteen (G. mangostana Linn.); however, little is known about the horticultural management of this species, and basic knowledge, such as asexual propagation or postharvest conservation, has not been reported. There is no information on ex situ conservation of this species in Mexico and Central America, and no selection of outstanding specimens with high quality fruits has been made. Most of the information reported so far for this species is about its ecology and medicinal properties.
