The World Flora Online

Les feuilles sont composées imparipennées, non stipulées, souvent groupées aux extrémités de gros rameaux. Les folioles se ressemblent beaucoup par le type de la nervation. Les nervures latérales sont bien marquées et réunies en arceaux nets près de la marge. Les Dacryodes sont remarquables par la présence de poils étoilés sur les fleurs et le plus souvent aussi sur les feuilles. Les autres genres ne montrent que des poils simples. Fleurs hermaphrodites (Aucoumea), ou unisexuées (Canarium, Dacryodes, Santiria), du type 3 ou 5. Présence d'un disque infrastaminal (Canarium, Dacryodes, Santiria), extrastaminal et réduit à des sortes de glandes (Aucoumea). Ovaire à 2-3 ou 5 loges biovulées. Fruits drupacés sauf ceux d'Aucoumea qui sont capsulaires. Cotylédons profondément laciniés (Dacryodes, Canarium).
