Abstract

Croton (Euphorbiaceae) includes more than 1,300 accepted species and new species of the genus are continuously being described, which are mainly from Brazil. Two new species, Croton aemulus and C. graomogolensis, are herein described, placed in C. sect. Barhamia subsect. Barhamia, and compared to C. muscicapa and C. longibracteatus. The new species are supported by their geographic distributions, ecology, and anatomical and morphological features. Both species are only known from the state of Minas Gerais, Brazil. Croton aemulus occurs in cerrado de altitude (mountain savannah) and C. graomogolensis occurs in campo rupestre (rupestrian grasslands) vegetation.
