A community‐derived classification for extant lycophytes and ferns
TLDR
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.
Two New Species of Isoetes (Isoetaceae) from northern Brazil
TLDR
Based on the IUCN criteria, it is suggested that Isoetes serracarajensis should be classified as vulnerable (VU) and I soetes cangae included as critically endangered (CR).
Species richness of pteridophytes in a montane Atlantic rain forest plot of Southern Brazil
ABSTRACT – (Species richness of pteridophytes in a montane Atlantic rain forest plot of Southern Brazil). A floristic survey ofpteridophytes (ferns and fern allies) was carried out in a 1ha plot in
Diversity of ferns and lycophytes in Brazil
TLDR
This compilation of ferns and lycophytes in Brazil is an update of the one published in 2010 and shows that the richest phytogeographic domain continues to be in the Atlantic Rainforest which also has the largest number of endemic and threatened species.
A classification for Blechnaceae (Polypodiales: Polypodiopsida): New genera, resurrected names, and combinations
TLDR
A new classification is proposed for the fern family Blechnaceae, with three subfamilies and 24 genera, with several phylogenetic analyses strongly suggest that Blechnum in the traditional sense is not a monophyletic group.
A comprehensive checklist of vascular epiphytes of the Atlantic Forest reveals outstanding endemic rates
TLDR
A pattern of endemism indicates the dominance of recent radiations of epiphytic groups in the Atlantic Forest, showing that the majority of divergences dating from the Pliocene onwards are similar to those that were recently reported for other Neotropical plants.
Molecular phylogeny of the fern family Blechnaceae (Polypodiales) with a revised genus‐level treatment
TLDR
This work outlines and explains a plan to resolve the polyphyly of Blechnum by recognizing additional, monophyletic, segregate genera, each corresponding to a highly supported clade across all analyses.
Adetogramma (Polypodiaceae), a new monotypic fern genus segregated from Polypodium
TLDR
Polypodium chrysolepis constitutes an isolated lineage among the neotropical polygrammoid ferns, close to Serpocaulon and the grammitids, and is recognized here in a new genus.
Seven new species of Selaginella subg. Stachygynandrum (Selaginellaceae) from Brazil and new synonyms for the genus
TLDR
The number of well-documented Brazilian Selaginella species is 61, of which 58 are native and three introduced and naturalized, and these statistics are likely to change with further work onSelaginella from Brazil.
