Palaquium is a genus of about 120 species of trees in the family Sapotaceae.[3] Their range is from India across Southeast Asia, Malesia, Papuasia, and Australasia, to the western Pacific Islands.[2][4]
Description
[edit]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.[4]
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.[4]
Some species, for example Palaquium gutta, are well known for producing gutta-percha latex.[4]
