Description and Ethnobotany

Growth Form It is a tree up to 50 m tall, with spreading buttresses up to 5 m tall.
Foliage It has alternate, stalked, compound leaves that are more than 1 m long. Each leaf consists of 4–15 pairs of leaflets, and lacks a terminal leaflet. The papery to leathery leaflets are egg-shaped to drop-shaped, slightly to distinctly sickle-shaped, red when young, dark green above and lighter green below when mature, hairless to covered with hair, 6–40 by 2–13 cm, and with toothed margins. The lowest pair of leaflets is smaller than others, round, ear-shaped or cushion-shaped, 0.4–3 by 0.3–5 cm, appearing like a stipule, and with one of the leaflets reduced.
Flowers The plant is monoecious, producing both male and female flowers in the same individual. The flowers are about 2–2.5 mm across, generally white to green-yellow, and occur on branched flowering stalks that are 15–70 cm long.
Fruits Its fleshy fruits have a stony core each. Its fruit is ellipsoid to round, 1.5–5 by 1–3 cm, and red turning black when ripe. The seed is egg-shaped, unequal sided, up to 2.5 by 1.5 cm, brown, and with a white covering (aril).
Habitat It can be found in primary and secondary forests, up to 1700 m altitude, and is common on riverbanks. It occurs locally in Bukit Timah Nature Reserve, Central Catchment Nature Reserve (including Mandai and Nee Soon Swamp forests), Changi, and Pulau Tekong Kechil.
Associated Fauna Its flowers are insect-pollinated. Its fruits and seeds are probably eaten and dispersed by small mammals, bats and birds. The lowest pairs of leaflets, that are stipule-like, are usually inhabited by ants.
Cultivation It can be propagated by seed.
Etymology Pometia, commemorating P. Pomet, a French writer; Latin pinnata, referring to the pinnate leaves of this species
Ethnobotanical Uses Edible Plant Parts (Edible Fruits)
