Croton adamantinus, C. corchoropsis, C. nummularius, C. rudolphianus, and C. virgultosus are found only in the sandstone complex of São José plateau, Buíque, growing up in rocky vegetation. Identification keys, descriptions, comments about morphological relationships and geographic distribution, and illustrations of species are provided.
