Abstract

An annotated checklist of species of Euphorbiaceae of the Guianas (Guyana, Surinam, French Guiana) and the adjacent region is presented and a key to the genera is provided. A total of 47 indigenous genera and 153 species are known from the Guianas, where species endemism is 14%, with the greatest number of endemics occurring in Guyana and the fewest in French Guiana. An additional 86 species and an additional seven genera are known from neighboring areas of the Guayana Region; many of these may be expected to occur in the Guianas. Taxa known only in cultivation in the Guianas include 22 species and an additional six genera. The following new combination is proposed,Croton vergarenae.
