Aglaia argentea

Description

Tree up to 30 m, sometimes flowering and fruiting at 4.5 m. Bark smooth, brown or greyish-green, longitudinally lenticellate; inner bark white, yellow or brown; sapwood pale brown, brown or reddish-brown; latex white, when present. Leaves in spirals particularly towards the ends of the twigs where they are close to- gether, imparipinnate, 17–112 cm long and 14–75 cm wide; petiole 4–41 cm, petiole, rachis and petiolules ridged and with indumentum like the twigs. Inflorescence up to 60 cm long and 60 cm wide, in the axils of the leaves near the apex of the shoot; peduncle up to 15 cm, peduncle, rachis, branches, pedicels and calyx with indumentum like the twigs. Male and female flowers similar, 2–4 mm long and 1.5–2.5 mm wide, ellipsoid, sessile or occasionally with pedicels up to 2.5 mm long. Petals 5, with some scales on the outside when young. Staminal tube shorter than the corolla, obovoid, aperture 0.5–0.6 mm across with an entire or shallowly 5-lobed margin, anthers 5, ovoid, included or just protruding. Fruits 3–3.5 cm long and 2–3 cm wide, ovoid or obovoid, with a short stipe up to 0.5 cm long, pericarp yellow or brown, den- sely covered with scales like those on the twigs, sometimes glabrescent; latex white; locules 2 (or 3) each containing 0 or 1 seed. Seeds completely surrounded with a soft, white, sweet or sweet-sour aril.

Morphology

The lower surface of the leaflets has a dense indumentum of white or brown peltate scales, the former gives them a silvery appearance, hence the specific epithet. There are at least two forms of this species, linked by intermediates; one has a darker indumentum, the lateral veins on the lower leaflet surface are prominent and the leaflet has a subcordate base; the other is less robust, the indumentum is white, the lateral veins are not prominent and the leaflet base is cuneate. Both are often found in second- ary and regenerating forest and forest edge. The form with the darker indumentum is, for example, conspicuous by its copper crown in the ravine along which the Padang- Bukittinggi road runs in West Sumatra. In addition to these two forms, some collec- tions from Thailand have small, coriaceous leaflets which are shiny dark brown above when dry.

Uses

The timber is not durable .
