Taxonomy

The leaflets of Aglaia leucophylla are pale green or yellowish-green when dry. The small stellate scales on the lower surface are often deciduous, leaving minute pits where they were attached. Aglaia leucophylla resembles A. edulis, but is distinguished from it by the more numerous scales on the lower leaflet surface and the pear-shaped fruits. Aglaia edulis has a subglobose, 3–locular fruit, although sometimes only one seed develops. The fruit of A. leucophylla is occasionally subglobose in, for example, the Philippines, with 2 lo- cules, each of which contains one seed.

Uses

Boles are used for house-poles (Borneo: Tumbang Tubus).
