Native to Singapore. A mid-canopy tree grows up to 40 m in height with pagoda shaped crown. Leaves are simple, arranged in whorls and exudes latex when broken. Trunk is deeply fluted and buttressed. Flowers are creamy white, fragrant.
Self-sown A. angustiloba can sometimes be seen in secondary forests. A. angustiloba and A. scholaris are commonly used in landscape planting.
Other than the difference in flower colours, A. scholaris (greenish yellow flowers) and A. angustiloba (creamy white flowers), A. scholaris can be differentiated from A.angustiloba by the stipule at the base of the leaf petiole. Looking at the fallen dried leaves, A. scholaris has side veins 0.25 to .64 cm apart, with distinct reticulations between them. In A. angustiloba, the sides veins are 0.25 cm or less apart without visible reticulations between them.
