Abstract

Croton josephinus Müll.Arg., a member of Croton sect. Medea (Klotzsch) Baill. (Euphorbiaceae), has not been recollected since 1824, nor mentioned in the literature since its original publication in 1873. This species has recently been rediscovered in a campo rupestre area at the ‘Pico 1430 m’ of the Serra de São José, Minas Gerais, after 20 years of field work in the area. In the protologue Croton josephinus was cited as having been collected from São Paulo State. This is likely to have been a simple misattribution of the area where it occurs. Based on the new material collected, a detailed description and an illustration of the species are provided. A lectotype and an isolectotype are designated.
