Key to Croton

A genus of about 1250 species, herbs, shrubs, and (rarely) trees, of nearly cosmopolitan distribution (primarily tropical and warm-temperate). Webster (1992, 1993a) considered the 2 taxa traditionally treated as Crotonopsis to be closely related to sections within Croton, such as section Gynamblosis; his reasoning has been supported by molecular phylogenetic studies and all recent floristic treatments and is followed here. The subgenera and sections shown in the key follow van Ee, Riina, & Berry (2011).
