Although over 90% of the territory of Tabasco is deforested, there were 48 taxa of ferns and lycophytes in a few semier- vergreen forest fragments in Tacotalpa. These correspond to 43 species, one variety, and one form of ferns, and three species of lycophytes, grouped in 28 genera and 17 families. This richness represents 36% of the taxa, 57% of genera, and 63% of the families of the fl ora of ferns and lycophytes of Tabasco. We found eight new records for the state (seven ferns and one lycophyte). These additions increase the pteridofl ora of Tabasco to 124 species, one subspecies, six varieties, and two forms. The genera with the largest number of species are Adiantum (5), Asplenium (5), and Thelypteris (4). As regards to life form, 22 species and one form are terrestrial, seven species and one variety are epiphytic, 12 species are terrestrial or epipetric, two species are epiphytic or epipetric, and three species are scandent. The locality with the largest number of species is La Pila (34), followed by Tomas Garrido (23), Oxolotan (19), and Grutas de Kolem Chen (15). The greatest number of species was observed in the interior of the semievergreen forest fragments (45), followed by the margins of the semievergreen forest fragments (33), and secondary vegetation (17). On the other hand, 14 species were observed only in the interior of the semievergreen forest fragments and one species on the margins of the semievergreen forest fragments. Furthermore, 30 species are present both at the interior and margins of the semievergreen forest fragments and 14 species in the three vegetation types. The species richness evidences the importance of these scarce fragments of semievergreen forest as effective refuge for the ferns and lycophytes.
