Abstract

ResumoEste estudo trata dos táxons de Pteridaceae encontrados nas formações ferríferas da Serra dos Carajás, estado do Pará, com descrições, ilustrações, distribuição geográfica e comentários. AbstractThis study addressed the Pteridaceae taxa recorded in ferruginous formations of the Serra dos Carajás, Pará state, with descriptions, illustrations, geographical distribution, and comments. In the study area nine genera and 10 species were recorded:

Pteridaceae in remnants of Cerrado in Maranhão state, Brazil

“…The Pteridaceae listed in this study represent around 42% of those taxa recorded from Maranhão state (33 species and three varieties) (Bastos and Cutrim 1999;Fernandes et al 2007Fernandes et al , 2010Fernandes et al , 2022Conceição and Rodrigues 2010;Conceição et al 2015;Prado et al 2022;Silva et al 2017;Silva Junior et al 2018. In inventories of ferns and lycophytes in Cerrado areas in Maranhão, one of the most species-rich families is Pteridaceae (Fernandes et al 2007(Fernandes et al , 2010(Fernandes et al , 2022Conceição et al 2015;Silva et al 2017) (Maciel and Pietrobom 2010;Fernandes et al 2012;Moura and Salino 2016;Silva Junior et al 2018, 2022Prado and Hirai 2022b), although some of them like Acrostichum aureum, A. danaeifolium, Adiantum dolosum, A. glaucescens, and Pteris tripartita also occur in the Atlantic Forest domain (Prado et al 2022).…”

Ferns and lycophytes from Serra dos Carajás, an Eastern Amazonian mountain range

“…In 2014 a project entitled "Flora of the canga of the Serra dos Carajás, Pará, Brazil" started from a partnership between the Museu Paraense Emilio Goeldi (MPEG) and the Instituto Tecnológico Vale de Desenvolvimento Sustentável (ITVDS), in collaboration with the Universidade Federal de Minas Gerais. From this project, floristic treatments of 22 families of fern and lycophyte occurring at the canga in Carajás were published between 2016 to 2018: Aspleniaceae , Cyatheaceae (Salino & Arruda 2016a), Dennstaedtiaceae (Salino & Arruda 2016b), Dryopteridaceae (Moura & Salino 2016a), Lycopodiaceae (Salino & Arruda 2016c), Lygodiaceae (Salino & Arruda 2016d), Oleandraceae (Salino & Arruda 2016e), Pteridaceae (Moura & Salino 2016b), Schizaeaceae (Almeida 2017), Selaginellaceae , Thelypteridaceae , Anemiaceae (Pallos et al 2017a), Blechnaceae , Gleicheniaceae , Hymenophyllaceae (Pallos et al 2017b), Isoetaceae (Pereira et al 2017), Lindsaeaceae (Pallos et al 2017c), Marattiaceae , Nephrolepidaceae (Viveros & Salino 2017a), Polypodiaceae (Almeida et al 2017), Tectariaceae (Viveros & Salino 2017b) and Ophioglossaceae (Salino 2018). These monographs included 70 species occurring in the open vegetation formations of the tops of the hills, known as vegetation associated with canga (Viana et al 2016).…”
