A floristic-taxonomic survey of the family Boraginaceae was carried out in a fragment of Caatinga vegetation of the Raso da Catarina Ecological Station, Bahia, Brazil. Seven species and three genera of Boraginaceae were found: Cordia (C. globosa (Jacq.) Kunth; C. leucocephala Moric.; C. rufescens A.DC.), Heliotropium (H. angiospermum Murray; H. elongatum (Lehm.) I.M. Johnst.) and Tournefortia (T. rubicunda Salzm. ex A.DC.; T. salzmannii DC.). Keys to identify genera and species are presented together with descriptions, illustrations, and comments on relationships among these taxa, distribution and habitat.
