Taxonomic history

The family Clusiaceae was divided by Cronquist into two subfamilies: the Clusioideae (typical subfamily) and the Hypericoideae. The latter was often treated as a family—the Hypericaceae or St. John's wort family. Elements of the Hypericoideae are more common in northern

areas and those of the Clusioideae are centered in the
tropics The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also refer ...
. Later classifications, however, divide the family in a finer way. Molecular studies have shown that the family Podostemaceae—the riverweeds—as well as the
Bonnetiaceae Bonnetiaceae is a family of flowering plants, consisting of 4 genera and 41 species. The family is Neotropical, with the exception of the genus ''Ploiarium'', which is found in Malesia. It is sister to the family Clusiaceae The Clusiaceae or ...
are nested in this group. Their inclusions make the Clusiaceae in a wide sense polyphyletic, and Stevens's subfamilies need to be recognised at family level: Clusioideae as Clusiaceae ''sensu stricto''; Hypericoideae as Hypericaceae; and Kielmeyeroideae as Calophyllaceae.
