• Inflorescence terminal, male one laxly paniculate, female one more dense; flowers 7-10 mm long, stamens 6.
• Infructescence 6-8 cm long with up to 4 fruits.
• Fruit an ellipsoid to obovoid drupe, circular to rounded triangular in cross-section, 30-60 mm × 17-30 mm, glabrous, containing 1-3 seeds.

C. patentinervium occurs in primary or secondary forest, sometimes in swamp forest, up to 450(-1200) m altitude, flowering mainly from November to May, fruiting from September to April. In Peninsular Malaysia, it is a common understorey tree. The density of the wood is 500-700 kg/m³ at 15% moisture content. Very closely related to Canarium littorale Blume.
