%X The Caatinga biome is located in the semi-arid region of northeastern Brazil and covers about 37 % of Piau¨ªstate. The main objective of the present study was a characterization of the Caatinga flora of the farm of Morro do Baixio,in state of Piau¨ª, Brazil (06¡ã51¡¯13¡± S; 41¡ã28¡¯15¡± W, at 400 to 540 m above sea level) in view of the fact that very few suchsurveys were conducted in the state. The flora of the farm was surveyed monthly, during a year, to gather herbs, epiphytes,parasites, sub shrubs, shrubs and trees. We encountered 136 species belonging to 46 families, including a new species ofBauhinia. The richest families were Caesalpiniaceae (15 spp.), Fabaceae (11 spp.), Bignoniaceae and Mimosaceae (both withnine spp.). We observed a higher frequency of typical species from sedimentary Caatinga. However, local conditions favorthe appearance of species that occur in Carrasco and Cerrado.
