Ptaeroxylaceae
Ptaeroxylaceae Juss. are a small family of Southern African indigenous trees and woody lianes, most of them from Madagascar, comprising only two genera. Such a family was not recognized by the APG II system of classification (2003), which noted that it was a synonym of Rutaceae. The APG III system of 2009, an updated version of the last system, did not mention the family. All species within this family are included within Rutaceae.
