Olacaceae is afamily offlowering plants in the orderSantalales. They arewoody plants, native throughout thetropical regions of the world. As of July 2021[update], thecircumscription of the family varies; some sources maintain a broad family, others split it into seven segregate families.
The 1998APG system and the 2003APG II system assign it to the orderSantalales in the cladecore eudicots. Prior to the advent of molecular data, the circumscription of the family Olacaceae varied widely between different authorities.[2] Among these various classifications, about 30 genera were included in the family. 15 genera are recognized for Olacaceae by theGermplasm Resources Information Network. The phylogenetic investigation published in 2008 recovered seven clades that were well-supported by molecular and morphological characters, but no formal taxonomic reorganization of the family was proposed. For this reason, Olacaceae in the broad sense was adopted by the APG III-system.[1] The formal reconfiguration of this family (as well as the rest of the order Santalales) was published by Nickrent and co-workers in 2010[3] and this concept is shown below. Olacaceae in the broad sense was split into seven families, and the genusSchoepfia was placed withArjona andQuinchamalium (both previously Santalaceae) in the family Schoepfiaceae.
