Eastern Borneo, central Sulawesi, the Moluccas (Morotai, Batjan, Aru Islands), New Guinea and the Louisiada Archipelago.

The wood is used as kedondong.

• Stipules caducous to persistent, inserted on or at the very base of the petiole, scaly to auricle-shaped; leaves with 3-9 leaflets, leaflets distinctly shortly bluntly acuminate at apex, acumen often emarginate, margin entire, almost glabrous or rarely tomentose below, with 10-25 pairs of secondary veins.
• Inflorescences terminal and in the upper leaf axils, paniculate.
• Flowers 3-6(-9) mm long, stamens 6.

Two subspecies have been distinguished. Subsp. maluense (synonyms: Canarium lian H.J. Lam, Canarium quadrangulare H.J. Lam) occurs from Sulawesi eastward. Five formae have been described within this highly variable subspecies. Subsp. borneense Leenh. differs mainly by its 8-9 mm long flowers, and occurs in eastern Borneo. C. maluense occurs in primary rain forest, up to 1100 m altitude. The density of the wood is 560-720 kg/m³ at 15% moisture content.
