摘要：Boraginales comprises approximately 125 genera and 2,700 species distributed worldwide. In Brazil, it is represented by 14 genera and 148 species grouped in four families. In this paper, we present the taxonomic survey of Boraginales in a Caatinga area located in the Curimataú Microrregion, where 10 species, two genera and two families were recorded: Cordiaceae, with two genera Cordia (one species) and Varronia (four species) and Heliotropiaceae, with three genera Euploca (one species), Heliotropium (two species) and Myriopus (two species). A key to the recognition of the families and species, as well as descriptions, illustrations, taxonomic comments and geographic distribution data to the species are provided.
