| Popis: | The aim of the present study was to describe the floristic composition of a rocky outcrop in Serra da Raiz, piedmont of Borborema, Paraíba, and verify the similarities or dissimilarities with other inselbergs northeastern Brazil. The work resulted in the registration of 138 plant species, and the families Fabaceae, Poaceae and Euphorbiaceae with the largest number of species. Comparing this work with other floristic studies, it appears that the rocky outcrop in piedmont Borborema shares floristic characteristics with the surrounding regions (seasonal forest) than with other inselbergs northeastern Brazil. Factors related to pediplanation, similarity to surrounding areas, geographical distances and heterogeneity of rocky outcrops were compared and discussed in this work. |
