Synopsis of the Genera and Suprageneric Taxa of Euphorbiaceae

Abstract

This revised synopsis of the taxa of Euphorbiaceae recognizes, and provides keys to, 5 subfamilies, 49 tribes, and 317 genera. Two new tribes, Croizatieae and Podocalyceae, are proposed, as well as four new subtribes, Leptopinae, Podocalycinae, Pycnocominae, and Tetracoccinae; five taxa are reduced to subtribal status. One genus (Ophellantha) is reduced to a section; 14 new binomial combinations are proposed. Lectotypifications are provided for almost all taxa not previously typified
