Garcinia oliveri is a cousin species of the mangosteen and also bears edible fruit. This plant is also known by local names ໂມງ (in Lao pronounced as /móːŋ/) in Laotian, Bứa núi in Vietnamese, and Tromoung in Khmer. It grows naturally in South-East Asia, including in Laos, Thailand, Cambodia and Vietnam.
This plant is a tree that grows up to 30 m high, with drooping branches. The leaves are large, thick, blade oblongs that are 10–27 cm long, attached to short petioles about 1 cm long. Its male flowers have 5 petals and 1 cm long stamens united into 5 bundles, while its hermaphroditic flowers have ovaries with 9–10 loculi. Its fruits are globose, about 4–5 cm in diameter, with red pericarp.[1]
In Vietnam, the plant's young leaves are used for food, such as being cooked in soup, or eaten fresh in a dish called banh xeo.
