Description

Tree up to 30(–40) m, sometimes flowering and fruiting at 4 m. Outer bark pale grey, greenish- brown, yellowish-brown, or reddish-brown with greyish–green patches, with longitu- dinal and transverse cracks and round lenticels; surface of inner bark green and pale yellow; inner bark green, pale orange-brown or reddish-brown; sapwood pale brown, pale yellowish-brown, dark orange-brown or reddish-brown, soft; latex white or exu- date pinkish-orange. Leaves imparipinnate, 30–83 cm long, 20–68 cm wide; petiole 6.5– 16 cm, petiole, rachis and petiolules with few to densely covered with scales like those on the twigs. Inflorescence up to 40 cm long and wide; peduncle up to 10 cm, peduncle, rachis and branches with indumentum like the twigs. Flowers 1.8–3 mm long, 1.7–3 mm wide, obovoid or ellipsoid, smelling of ci- tronella, pedicels 0.8–2 mm, densely covered with scales like those on the twigs. Petals 5. Staminal tube slightly shorten or longer than the corolla, either with a shallowly 5-lobed aperture c. 0.5 mm in diam. or with a minute apical pore at the apex c. 0.3 mm across, occasionally with a few stellate scales on both surfaces or simple hairs inside; anthers 5, narrowly ovoid, inserted about 1/6–1/3 up the tube and included or just protruding, with a few pale brown stellate scales. Fruits 1.5–3.2 cm long and 1.5–3 cm wide, ellipsoid or subglobose, sometimes laterally compressed and then c. 2.3 cm thick, with a longitudinal ridge en- circling the fruit; the pericarp either thin or hard and woody and up to 5 mm thick, brown, orange, yellow, white or green, densely covered with pale brown stellate scales on the outside; fruitstalks c. 2 mm. Seed up to 2.3 cm long, 1.4 cm wide and 1 cm thick, ovoid, the inner surface flattened; with a complete gelatinous, translucent, sweet-sour edible aril. 2n = 68 .

Taxonomy

The leaflets of Aglaia leptantha have a cudate, obtuse acumen and are sometimes markedly asymmetrical at the base; the peltate scales are usually pale, with a fimbriate margin and a darkc entral sport; the secondary venation visible or subprominent. Aglaia pervidis is also similar to A. leptantha; the differences are described under A. pervidis. Aglaia glabriflora is a form of A. leptantha but one which cannot be clearly differentiated from it and is included as conspecific. At Kuala Lompat in Pahang, Peninsular Malaysia, 'A. glabiflora' is foind in closed forest and 'A. gamopetala' in partially cleared forest where there is more light. At this site they can be distinguished, but appear to be closely allied. Aglaia gamopetala has larger leaves, paler indumentum, and larger flowerrs in which the staminal tube extends beyond the corolla and has a minute apical pore; in 'A. glabiflora', ithe inflorescence is without scales and the aperture of the staminal tube is wider. However, intermediates between these two are found in other parts of their range.

Uses
