A provisional synopsis of the sections of the genus Croton (Euphorbiaceae)

Summary Webster, G. L.: A provisional synopsis of the sections of the genus Croton (Euphorbiaceae). – Taxon 42: 793‐823. 1993. – ISSN0040‐0262. The 19th century classification of Croton by Müller Argoviensis is highly artificial. A revised system that incorporates the sections proposed by Baillon and Grisebach is presented, with a key to the 40 sections recognized. For each section, types and synonymy are indicated, along with a description and list of representative species. Described as new are 2 sections (C. sect. Anadenocroton, sect. Corylocroton) and 3 subsections (C. subsect. Cuneati, subsect. Matourenses, subsect. Sampatik); 2 new sectional names (C. sect. Argyrocroton, sect. Luntia) represent changes in rank.
