Tree up to 27 m, sometimes small and unbranched. Bark smooth, grey, with shallow longitudinal fissures; inner bark brown or dark brown; sapwood pinkish-brown, brown or yellow; latex white. Leaves in spirals towards the ends of the twigs where they are very close together and the expanded bases of the petioles overlap, imparipinnate, up to 135(–200) cm long and 80 cm wide; petiole up to 20 cm long, up to 2 cm across at the base, petiole, rachis and petiojules with indumentum like the twigs; latex white. Inflorescence up to 30 cm long and 15 cm wide, the final branches up to 20 mm long and densely packed with sessile flowers; peduncle up to 7 cm, peduncle, rachis and branches clothed like the twigs Flowers up to 2 mm in diam. Petals 5, c. 1.5 by 0.6 mm. Staminal tube c. 1 mm long, shorter than the co- rolla, subglobose with the aperture wide and deeply 5-lobed; anthers 5, ovoid, half to nearly as long as the tube and just protruding through the aperture. Fruits brown, up to 5 cm long and 4.5 cm in diam., obovoid, sometimes with a small beak, with a thick indumentum of hairs up to 4 mm long like those on the twigs, fruitstalks up to 2 cm.

A distinctive form of this species, which may merit recognition as a subspecies, occurs on ultrabasic rock in the Philippines. It has smaller leaflets which have a reddish- brown indumentum on the lower surface and recurved margin; it has not been formally described and named by the present author, because no distinguishing floral or fruit character has been found in the specimens examined. The hairs of Aglaia grandis have a central rachis from which radiate 2–4 whorls of arms. The arms of the hairs on the twigs and fruits are long and the indumentum is dense forming a continuous, pale brown woolly covering. The hairs also densely cover the lower surface of the leaflets, but the surface is visible between the hairs. There are as many as 36 lateral veins on each side of the midrib. The twigs, petiole, rachis and peduncle are terete.
