The aim of this study was to provide information on the ecology and floristic composition of vascular epiphytes on specimens of licurizeiro (Syagrus coronata), palm tree native to the Brazilian Backlands, whose individuals were isolated in pasture areas in the municipality of Várzea da Roça - BA. The epiphytic species were classified according to their ecological category and dispersion forms. The vascular epiphytes were represented by 26 species, 21 genera and seven families, and Bromeliaceae (8 spp.), Cactaceae (7 spp.), Polypodiaceae (4 spp.) and Orchidaceae (3 spp.) the most representative. The true holoepiphytes and accidental epiphytes were the most frequent categories, gathering, respectively, 42.31% and 30.76% of the species inven-toried. Regarding the dispersion forms, it is observed the predominant of zoochoric species (14 spp.) while anemochoric were represented by 12 species. The results show the importance of licurizeiro in the maintenance of the epiphytic community in areas of Caatinga and show its role as maintainer of biological diversity in an-thropogenic environments.
