ABSTRACT
This study aimed to inventory the ferns and lycophytes of Morro do Pico (22°56'05.2'' S, 43°07'13.8''W), which is located in Fortes Environmental Protection Area, in the coastal region of Niterói, in Rio de Janeiro State, Brazil. This area is formed by a rocky outcrop and an adjacent Atlantic Forest remnant. Fieldworks were carried out from May to October 2014, the material was dried and incorporated to the Herbarium from Museu Nacional (R). The identification key is presented according to diagnostic morphological characters. We record ten families, distributed in fifteen genera and twenty-six species. Families with highest species richness were: Pteridaceae (10 spp.), Anemiaceae (four spp.) and Selaginellaceae (three spp.). The adjacent forest presents greater richness in relation to the inselberg. Among the taxa found only in this formation, it stands out Anemia tomentosa var. anthriscifolia, Doryopteris collina, Selaginella convoluta e S. sellowii.
