Epiphytes are autotrophic vascular plants that germinate, take root and grow on other plants for support. In the interaction known as vascular epiphytism, the epiphyte uses only the substrate provided by the host plant, being independent of the phorophyte for water and nutrition. Epiphytes contribute to biological diversity in plant communities, play an important role in primary productivity and nutrient cycling, may be ecological indicators of successional stage of the forest and are essential in the process of degraded areas recovery and forest enrichment. The recent recognition of the tropical forest canopy as storehouses of biodiversity on the planet has encouraged studies that seek to understand the processes involved in epiphytic community, highlighting their role in ecosystem function. In addition, few studies about epiphytes in Brazil were carried out in the cerradão (woodland savanna), in the seasonal semideciduous forest without fluvial influence and, in the seasonal semideciduous forest with permanent fluvial influence (swamp forest) occurring in the same region, where there is no air relative humidity constancy throughout the year. These plant formations occur in the municipality of Bauru and were selected as study areas for the development of this research. The purpose of this dissertation is to contribute to the knowledge of the floristic composition and structure of the epiphytic component in the three plant formations, analyzing the floristic similarity, diversity and vertical distribution
