This dataset contains the digitized treatments in Plazi based on the original journal article Castro-Aguiar, Pedro Henrique, Fernandes, Rozijane Santos, Zappi, Daniela Cristina (2025): Ferns of the Parque Nacional das Nascentes do Rio Parnaíba Brazilian Cerrado. Rodriguesia (e 00612024) 76: 1-24, DOI: 10.1590/2175-7860202576004, URL: https://doi.org/10.1590/2175-7860202576004
Abstract
The floristic and taxonomic treatment of ferns from the Parque Nacional das Nascentes do Rio Parnaíba (PNNRP), a protected area in the northern portion of the Brazilian Cerrado, within the boundaries of the states of Maranhão, Tocantins, Piauí and Bahia, is presented. Considered the largest full protection area of the Cerrado, the PNNRP is in a region rapidly losing its native coverage due to the expansion of agribusiness. This treatment includes identification keys for genera and species, descriptions, comments on diagnostic and ecological characteristics, species distribution, and illustrations. Twenty-five species were recorded in the study area, distributed in 11 families. Blechnum areolatum and B. asplenioides were recorded for the first time in the state of Maranhão, while Pteridium esculentum var. harpianum, Dicranopteris flexuosa, Trichomanes pilosum and Meniscium serratum are new records for the state of Piauí.

Resumo
É apresentado o tratamento florístico-taxonômico das samambaias do Parque Nacional Nascentes do Rio Parnaíba, uma Unidade de Conservação (UC) situada na porção norte do Cerrado brasileiro, nos limites dos estados do Maranhão, Tocantins, Piauí e Bahia. O Parque é considerado a maior área de proteção integral do Cerrado e está localizado em uma região que está perdendo rapidamente sua cobertura nativa devido à expansão do agronegócio na área. Este tratamento inclui chaves para a identificação para famílias, gêneros e espécies, ilustrações, descrições, comentários sobre características diagnósticas e ecológicas, bem como a distribuição geográfica das espécies. Na área de estudo, foram registradas 25 espécies distribuídas em 11 famílias. Blechnum areolatum e B. asplenioides foram registrados pela primeira vez no Maranhão, enquanto Pteridium esculentum var. harpianum, Dicranopteris flexuosa, Trichomanes pilosum e Meniscium serratum são novos registros para o estado do Piauí.
