Description
Tree up to 20 m, usually with a broad rounded crown.
Outer bark brown, pale green, pale orange-brown, pinkish-brown, pale brownish-grey or grey, sometimes with transverse and longitudinal striations or rows of lenticels; inner bark yellowish-brown, orange or green: sap wood brown or pale yellowish-pink, pale brown or orange; heartwood ma- genta, sometimes with white latex.
Leaves in spirals which become dense towards the ends of the twigs, imparipinnate, up to 90 cm long and 60 cm wide; petiole up to 20 cm, petiole, rachis and petiolules ridged and with in- dumentum like the twigs, but the scales sometimes brown throughout.
Petals 5.
Staminal tube c. 1 mm long, 1 mm wide, obovoid, the aperture c. 0.5 mm across, shallowly 5-lobed, with white stel- late hairs in dense clumps on the inner surface of the tube near the apex and few on the outer surface; anthers c. 0.5 mm long, 0.3 mm wide, ovoid, reaching or protruding just beyond the aperture, densely covered with white stellate hairs.
Fruits narrowly ob- ovoid when young, up to 5 cm long, 3.5 cm wide and subglobose, often with a short beak up to 5 mm and a short stipe up to 5 mm when mature, brown or yellow, densely covered with brown peltate scales.

Morphology
Aglaia squamulosa is readily distinguished by the markedly rugose upper sur- face of the leaves and the numerous peltate scales on the lower surface from which the specific epithet is derived. Aglaia densisquama, which is known only from Sarawak, appears to be an extreme but distinct variant of A. squamulosa and is treated here as a separate species. It has spindle-shaped fruits, which are rarely found in A. squamulosa in Borneo (e.g. in Chai S 36154).
