The predominant biological types were hemicryptophytes, nanophanerophytes and microphanerophytes, and in the endemisms nanophanerophytes, microphanerophytes and hemicryptophytes stood out. In the territory it was obtained that 4.6% of the families contributed the largest number of genera (42.6%) and species (38%). The families with the largest number of genera and species were: Asteraceae, Rubiaceae and Fabaceae. The most abundant genera in species were Thelypteris, Asplenium, Miconia, Peperomia, Tillandsia, Eugenia, Cyperus, Paspalum.
