Baccaurea macrocarpa, commonly known as tampoi, is a fruit-bearing tree in the Phyllanthaceae family native to the lowland rainforests of Borneo and parts of Peninsular Malaysia. This species is known for its striking cauliflorous habit, producing large, round, orange to reddish fruits directly on the trunk and major branches. The thick rind encloses soft, aromatic, sweet–tart pulp that is eaten fresh and highly prized locally. As a wild and semi-cultivated species, Baccaurea macrocarpa plays an important ecological role by feeding forest wildlife and supporting understory diversity, while culturally it remains an iconic heritage fruit of the region.
