Comment:
According to the most recent taxonomic research by the Angiosperm Phylogeny Group (APG-III), the traditional concepts of Euphorbiaceae were no longer found satisfactory. Many genera, formerly included in this family, have therefore now been placed in separate families.
The genera formerly making up the subfamily Phyllanthoideae are now placed in Phyllanthaceae, with the exception of
Drypetes, which has been placed in the small family Putranjivaceae;
The genus Clutia has been placed in the small family Peraceae.
