Aglaia korthalsii

Description

Tree up to 26 m. Bark pale to dark reddish-brown or pinkish-brown or orange brown, sometimes with coarse longitudinal fissures or rows of lenticels, flaking in large irregular roundish scales, exposing orange or yellowish-green bark beneath; inner bark pink, dark green- ish-pink or purplish-pink, fibrous; sapwood pale pink, pale yellow, yellow or white; latex white. Leaves up to 40 cm long and 48 cm wide, obovate in outline; petiole 7–12 cm, petiole, rachis and petiolules with numerous scales like those on the twigs. Inflorescences borne in leaf axils or on old wood of the twigs. Flower c. 1.5–2 mm long and 1.6–2.5 mm wide; pedicel 0.8–3 mm; calyx with few to numerous peltate scales like those on the twigs, divided almost to the base into 5 rounded lobes which have fimbriate margins. Petals 5. Staminal tube 0.8 mm long, 1.9 mm wide, obovoid or cup-shaped with the apical margin incurved and shallowly 5-lobed; anthers 5, c. 0.4 mm long, ovoid, inserted inside the rim of the tube, protruding and pointing towards the centre of the flower. Fruits 2–4 cm long, 1–3.5(–5) cm wide, ellipsoid or subglobose, orange, densely covered with orange-brown peltate scales which have a fimbriate margin on the outside and with small longitudinal wrinkles, the pericarp indehiscent with a dehiscence line running longitudinally around the fruit along which the ripe fruit breaks open when pressure is applied, the pericarp 1–10 mm thick, fibrous and flexible, with some white latex, the inner surface, without hairs or scales, shiny orange; fruitstalks 1–2 cm. Seeds 1.5–2 cm long, 1–1.5 cm wide, 0.8 mm through, ellip- soid, with inner surfaces flattened; aril c. 2 mm thick, translucent yellow or pale orange, juicy or gelatinous, edible, sweet or rather bitter tasting, firmly attached to the testa es- pecially at the hilum and main antiraphe vascular bundle, usually not quite complete on the antiraphe side, the seed coat with branched venation. 2n = 84 .

Taxonomy

Aglaia korthalsii is separated from A. speciosa by its usually 5 larger leaflets, less dense indumentum, and its fruits. The fruit of A. korthalsii is usually similar to that of A. elliptica in that it is indehiscent and has a longitudinal ridge along which the ripe pericarp splits into two if pressure is applied, but the indumentum is of peltate scales in A. korthalsii, whereas it is of stellate scales in A. elliptica. In Celebes, A. kort- halsii is sometimes ramiflorous.

Uses

Edible fruits. Timber used for house poles.
