Geographical Distributions

Aglaia lawii is distributed from India, through Burma (Myanmar), Thailand, Indo-China and throughout Malesia towards the Solomon Islands.


Aglaia lawii is a medium-sized to fairly large tree which can reach up to 40 m tall. Its bole is branchless for up to 15 m, measures up to 200 cm in diametre, fluted or with but­tresses up to 1.8 m high. The bark surface is reddish ­brown to yellowish-brown or pale pinkish-brown but sometimes grey or greenish-brown while the inner bark is green.

There are (1-)2-7(-11) leaflets which are arranged alternate to subopposite, with 5-21 pairs of secondary veins, with nu­merous pits on both surfaces, smooth on both surfaces or with numerous pale brown or pale orange-brown peltate scales with an irregular to fimbriate margin on the lower surface.

The flowers are 3-4(-6)-merous, with (5-)6-10(-11) anthers and an ovoid style-head with (2-)3 apical lobes or columnar with a truncate apex. The fruit is (2-)3(-4)-locular and dehiscent.

Ecology / Cultivation

Aglaia lawii is locally common and occurs in primary or secondary evergreen to deciduous forests, some­times in peat swamp or riverine forests, on sandy to clayey soils or limestone, from sea level up to 1650 m altitude. The wood is reported as hard and durable and has a density of 590-995 kg/m3 at 15% moisture content.
