The occurrence of Lycopodiella cernnua (L.) Pichi-Sermolli (Pteridophyte: Lycopodiopsida: Lycopodiaceae) on mangrove bordering areas, São Luís – MA - Brazil.
The Pteridophyte division is represented by vascular criptogams of very varied habits, which may range from arborescent forms, of erect stems and large leaves up to small size, almost microscopic forms. Lycopodiella cernnua specimens were collected, on the margins of Parna Açu’s mangrove, located in the southwest of the São Luís Island. Pteridophytes specimens were observed with great frequency on a hillside located on the bordering area of this mangrove where high humidity rates were recorded. Regarding the habitat, they are terrestrial, of open and humid sites, such as ravines; they are virtually cosmopolitan and very variable.
Key words: Pteridophyte, Lycopodiella cernnua, mangrove.
