The Simaroubaceae are a small, mostly tropical, family in the order Sapindales. In recent decades, it has been subject to much taxonomic debate, with several small families being split off. A molecular phylogeny of the family was published in 2007, greatly clarifying relationships within the family. Together with chemical characteristics such as the occurrence of petroselinic acid in Picrasma in contrast to other members of the family such as Ailanthus this indicates the existence of a subgroup in the family with Picrasma, Holacantha, and Castela.
The best-known species is the temperate Chinese tree-of-heaven Ailanthus altissima, which has become a cosmopolitan weed tree of urban areas and wildlands.
Well-known genera in the family include the tropical Quassia and Simarouba.
