This species is known from at least 80 localities from Myanmar (lower), Cambodia and Thailand (lower), Penninsular Malaysia, Singapore, Indonesia, Brunei, the Philippines, Papua New Guinea (incl. New Britain) and the Solomon Islands. It has a very large extent of occurrence (EOO of 12,160,255 km², but this is an underestimate as it is based on an incomplete map). It is known from at least four protected area and is likely to be under collected. It grows in forest, often along coast and rivers, at altitudes up to 1,500 m altitude. There is a decline in the habitat, however, given the large extent of occurrence and the number of known localities, it is considered as Least Concern.

This tree species is known from Myanmar (lower), Cambodia and Thailand (lower), Peninsular Malaysia, Singapore, Sumatra, Borneo (Sabah, Sarawak, Brunei and Kalimantan) Java, the Philippines, Sulawesi, Moluccas, Papua, Papua New Guinea (incl. New Britain) and the Solomon Islands.
