The species is found from northwestern islands of the Sahul/Australian continent, across southern Wallacea and throughout Southeast Asia:[2][12] Indonesia (Aru Islands, southern Maluku, East and West Nusa Tenggara, Bali, Jawa, Sumatera, Kalimantan), Timor Leste, Singapore, Malaysia (Peninsular Malaysia, Sabah, Sarawak, Brunei, the Philippines (Mindanao including Bangsamoro and Mimaropa), Thailand, Cambodia, Vietnam, Laos, Myanmar and India (Andaman Islands, Nicobar Islands, Odisha).
The varieties alticola and atjehensis are found in Sumatera.[13][14] The varieties brevipes, castaneus and rejangensis are found in Borneo.[6][7][10] The varieties longipetiolatus and nutans are found from Borneo to the Philippines (notably Palawan for var. longipetiolatus and the Sulu Archipelago for var. nutans)[8][9] The variety siamensis is found in Thailand, Myanmar and India (including Assam and notably Odisha).[11]
Habitat
In Cambodia and Vietnam it is found in open formations and in gallery forests, the edges of dense/closed forests.[3] In Thailand's Thung Yai Naresuan Wildlife Sanctuary it is a component of semievergreen forest.[15]
Ecology
Parts of the plant (particularly the fruit) are eaten by[16] the fruitbats Balionycteris maculata, Chironax melanocephalus, Cynopterus brachyotis[5] and Cynopterus horsfieldii, the kanchil Tragulus kanchil, the langur Presbytis femoralis, the pheasant Lophura erythrophthalma, the porcupine Trichys fasciculata, the rats Leopoldamys sabanus and Maxomys whiteheadi, the squirrels Rhinosciurus laticaudatus and Lariscus insignis, and the treeshrew Tupaia glis.
