The work presents species of ferns and lycophytes from a remnant of Atlantic Forest located in a semi-arid region, in the Serra da Jibóia, municipality of Santa Teresinha, State of Bahia, Brazil. We also analyzed the floristic similarities of this area with other regions in Brazil. In total, 97 species were presented, representing 51 genera and 22 families. The most representative families were Dryopteridaceae (17 spp.), Polypodiaceae (16 spp.), Pteridaceae (12 spp.), and Hymenophyllaceae (10 spp.). Most species occur as epiphytes (48%), whereas 38% are terrestrial, 3% are lythophyte, 3% are hemiepiphyte and 8% present more than one type of habit. The similarity analysis showed that the flora of ferns and lycophytes from Serra da Jibóia is related to the Southern Bahia State and Southeastern Brazil areas, suggesting similar environmental conditions among those areas.
