Abstract
The order Ericales in the Atlantic Forest remnants of Usina São José was partially published in the taxonomic treatment of Sapotaceae. Following the series of publications of Usina São José, in this paper the treatment of Ericales is updated with the families Lecythidaceae, Marcgraviaceae and Primulaceae. We recorded six genera and eight species for these families. Lecythidaceae is represented by three genera and four species, Marcgraviaceae by two genera and two species and Primulaceae by one genus and two species. For the genera Eschweilera and Myrsine we recorded two species each and for the other genera we recorded one species each. This paper has an identification key and descriptions for the species, ecological and taxonomic comments for genera and species.
