The Caatinga is the largest Seasonally Dry Tropical Forest (SDTF) in South America with diverse geomorphological features. The “altitude marshes”, exceptional areas with altitudes above 700 m that were established in the humid mountains of the Caatinga, shelter vegetation characteristic of other phytogeographic domains. Despite the importance of these areas for the Brazilian semi-arid region, several of them still remain unknown, or little known, floristically. This study aims to update the floristic inventory of angiosperms in the recently created Serra do Teixeira National Park (PARNA), previously called Pico do Jabre State Park, in the State of Paraíba, Northeast Brazil. The checklist was prepared through field trips between 2018 and 2020 and compiled from a list of species published in 2004. The study compiled 335 species distributed in 70 families and 220 genera, while Fabaceae, Malvaceae and Asteraceae were the most representative families. Species richness depending on altitude was initially observed to be increasing, however, upon reaching intermediate levels of the altitudinal gradient, a decline in richness was observed, which continued to decrease until the top of the massif. Of the total number of documented species, there are representatives widely distributed in the Brazilian territory (141 spp.) as well as species also associated with the phytogeographical domains of Caatinga (281 spp.), Cerrado (254 spp.), Atlantic Forest (263 spp.), Amazon (157 spp.), Pampa (76 spp.) and Pantanal (82 spp.). The results demonstrate that the PARNA of Serra do Teixeira constitutes an important refuge for plant biodiversity, especially in the semi-arid region of Paraíba and Brazil.
