Primary and secondary (logged) forests, wet evergreen forests, dipterocarp forests, swamp forests, kerangas
forests, montane forests, mossy forests, along forest roads, ridges, streams, on gentle to steep slopes,
on rock in dry exposed areas, common in undergrowth and abundant in open areas. Soil: red, yellow sandy or
light brown clay, limestone, acid sand. Found from 50 to 1980 m elevation.
Cosmetic use as tooth paste to dye the teeth black: burned wood exudes a black latex, which is smeared on
the teeth. Repeated treatments are needed after 3 days otherwise the colour disappears.
