Palaquium is a genus of about 120 species of trees in the family Sapotaceae.[4] Their range is from India across Southeast Asia, Malesia, Papuasia, and Australasia, to the western Pacific Islands.[3][5]

Description

Within their range, Palaquium species are mostly found in the Philippines and Borneo. In Borneo, many species are recorded in the Malaysian states of Sabah and Sarawak.[5]

The leaves are typically spirally arranged and often clustered near twig ends. Flowers are mostly bisexual, though some unisexual instances are known. Fruits are one- or two-seeded with rare instances of several seeds. Palaquium habitats are coastal, lowland mixed dipterocarp, swamp, and montane forests.[5]

Some species, for example Palaquium gutta, are well known for producing gutta-percha latex.[5]
