The history of systematic classification of this genus is changeable. In the processing for the Flore de Madagascar et des Comores from 1991 Cedrelopsis was filed together with the monotypic African genus Ptaeroxylon in the small family Ptaeroxylaceae. Later, an assignment to the mahogany family ( Meliaceae ) was performed. Meanwhile, the former Ptaeroxylaceae be included in the wider circumscribed Rutaceae ( Rutaceae ). The genus belongs to the subfamily Cedrelopsis Spathelioideae within the family of Rutaceae.
