Vatica rassak is a tree in the family Dipterocarpaceae, native to Maritime Southeast Asia. The specific epithet rassak is from resak, the species' Malay common name.^[3]

Description[edit]

Vatica rassak grows up to 30 metres (100 ft) tall, with a trunk diameter of up to 70 cm (28 in). Its coriaceous leaves are elliptic to oblong and measure up to 32 cm (13 in) long. The inflorescences bear cream flowers.^[3] In Borneo, a newly discovered, unnamed special caterpillar makes use of the poisonous resin from this tree to build a cocoon.^[4]

Distribution and habitat[edit]

Vatica rassak is native to Borneo, Java, the Maluku Islands, Sulawesi, New Guinea and the Philippines. Its habitat is along rivers and in lowland dipterocarp forest, at altitudes to 400 m (1,300 ft).^[1]
