【 摘 要 】
A floristic survey of pteridophytes (ferns and fern allies) was carried out in a 1ha plot in the Pico do Marumbi State Park, Morretes, State of Paraná, Southern Brazil. The study area is covered with a closed ombrophilous forest (Brazilian Atlantic Forest) and lies approximately 630 m in elevation. All species and life-forms of pteridophytes growing in the plot were registered and most of them were collected for taxonomic identification. A total of 81 species, belonging to 17 families were registered. The richest were Polypodiaceae (12 species), Hymenophyllaceae (11) and Lomariopsidaceae (11). The richest genera were Asplenium (ten species), Elaphoglossum (10) and Trichomanes (six). Life-form composition was: epiphytes (49 species), terrestrials (28), lithophytes (two), epiphytes/terrestrials/lithophytes (one) and epiphytes/lithophytes (one). No hemiepiphytes were found. Terrestrials included herbaceous (22 species), arborescent (four) and climbing (two). Species richness of the plot can be considered as high when compared to other neotropical sites.
