Fruits several times recorded as poisonous. According to various authors the roots and leaves are medicinal. According to HEYNE () the bark is used for spinning threads for fishing tackle in Sumatra's West Coast. JACOBS (n. 5003) mentioned: 'The wood smells a bit of HCN; vessels contain potable water'.


The fruits are sometimes 4-carpellate. Often larva feeding on the pollen are found. Deformed galled flowers occur regularly. Flowers are once reported as odorless; the urceolate flowers enclosing the anthers, however, suggest entomogamy.
