ABSTRACT – (Bromeliaceae and Orchidaceae on rocky outcrops in the Agreste Mesoregion of Paraíba State, Brazil). The present study consists of the floristics-taxonomic survey of Bromeliaceae and Orchidaceae on rocky outcrops located at an Atlantic Forest-Caatinga transition area in Paraíba State, northeast of Brazil, in order to provide data for the implementation of the biota conservation’s policies, especially of the flora associated to rocky environments of Paraíba State, given that the taxonomic studies focusing on such families in this state are still incipient. During the study, ten species in six genera of Bromeliaceae and six species in five genera of Orchidaceae were recorded. The treatment includes keys for recognition of the species of families, morphological descriptions, illustrations, geographic distribution data, and comments on the phenology of the species. Keywords: Brazilian flora, semiarid, monocotyledon.
