The caatinga biome covers around 70% of the North-Eastern territory and nevertheless the studies carried out about its natural riches are still insufficient especially tackling the floristics diversity of the biome as a whole, particularly in the state of Paraiba. For this reason the current study aimed to carry out the floristics survey of an area of caatinga in the municipality of Boqueirão, Paraiba State. In the area of study, it was registered 47 species distributed in 39 genera and 20 families of flowering plants. The families that stood out in number of species were: Fabaceae, with 12 species; Cactaceae, with five; Euphorbiaceae and Malvaceae, with four species each one and Convolvulaceae with three species, while the other families (15) showed one to two species each one. The woody component dominated over the shrubby, herbaceous, subshrubby and the woody vines components of the area studied. Based on the data obtained in this study, it was possible to correlate the taxa shown with the flora of different areas of caatinga, especially in the Northeast region, showing up the priority of carrying out floristics studies including other areas of the caatinga of Paraiba as well as of different states of the Brazilian Northeastern.
