Xanthophyllum is a genus of about 109 species of trees and shrubs, of the plant family Polygalaceae;[3][2] (under the Cronquist system it was previously placed in the monotypic family Xanthophyllaceae). The generic name is from the Greek meaning "yellow leaf", referring to how the leaves are often yellow when dry. In Borneo it is known as minyak berok in Malay or nyalin in the Iban language.[4]
Xanthophyllum species grow as trees or shrubs. Their twigs are often smooth and are coloured green or yellow. Leaves, when not drying yellow, dry green or dark brown. Flowers feature five petals. The mostly roundish fruits are not winged and measure up to 15 cm (6 in) in diameter. Fruits of some species are considered edible, e.g. X. ecarinatum, X. obscurum and X. stipitatum.[4]
Xanthophyllum grows naturally from India in tropical Asia to northern Australia. The majority of species grow in lowland rainforest. Some species grow at higher altitudes in hill or montane forests. Others occur in peatswamp or kerangas forests.[4]
