TL;DR: A modern, comprehensive classification for lycophytes and ferns, down to the genus level, utilizing a community‐based approach, that uses monophyly as the primary criterion for the recognition of taxa, but also aims to preserve existing taxa and circumscriptions that are both widely accepted and consistent with the understanding of pteridophyte phylogeny.

TL;DR: Two new species of Ctenitis (Dryopteridaceae) from South America are described and illustrated and seven lectotypifications and two new synonyms are proposed.

TL;DR: In this paper, the authors surveyed lycophyte and fern species in four forest fragments in western Parana, Brazil, and compared them to 15 other fragments with different plant formations from the Atlantic Forest biome in southern Brazil.

TL;DR: In this paper, taxons de Tectariaceae encontrados in formacoes ferriferas da Serra dos Carajas, estado do Para, were investigated.

TL;DR: Based on collections of 45 Herbaria in addition to newly collected specimens and some field observations, a taxonomic treatment for South American Ctenitis is provided, a hundred years after Christensen’s monographs.
