Olacaceae

Olacaceae is a family of flowering plants in the order Santalales. They are woody plants, native throughout the tropical regions of the world.

The 1998 APG system and the 2003 APG II system assign it to the order Santalales in the clade core eudicots. Circumscription of the family Olacaceae varies between different authorities. About 28 genera are accepted in the family, out of which a total of 15 by the Germplasm Resources Information Network. However, the circumscription of the family are still under investigation and some authors split the family into smaller entities. The formal reconfiguration of this family (as well as the rest of the order Santalales) proposed by Nickrent and co-workers, has not been recognised by the APG III-system of 2009.
