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.
Plastome sequences of an ancient fern lineage reveal remarkable changes in gene content and architecture.
TLDR
The plastomes of Schizaea are the smallest reported for a fern so far, and posttranscriptional modification of RNA is likely a common phenomenon in this clade as well.
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.
Phylogeny and historical biogeography of the lastreopsid ferns (Dryopteridaceae).
TLDR
Diversification among the main clades of the lastreopsid ferns was influenced by climatic and geological changes in the southern hemisphere, and taxonomic recognition of Parapolystichum is warranted to preserve the monophyly of Lastreopsis.
Synopsis of Mickelia, a newly recognized genus of bolbitidoid ferns (Dryopteridaceae)
TLDR
A key to the genera of bolbitidoid ferns and a synopsis of Mickelia that gives for each species a complete synonymy, geographical distribution, comparative discussion, and illustration are provided.
Evolution of Spore Morphology in the Blechnaceae
TLDR
To optimize spore characteristics of the exine and perine on a phylogenetic tree, infer their evolution within the Blechnaceae, and determine whether the characters define any of the genera or subfamilies.
The Phylogenetic Relationship of Tectaria brauniana and Tectaria nicotianifolia, and the Recognition of Hypoderris (Tectariaceae)
TLDR
To preserve the monophyly of Tectaria, T. brauniana and T. nicotianifolia are classified in Hypoderris, a genus previously considered monotypic and characterized by creeping rhizomes, two-ranked leaves, and spiny perispores.
Stenogrammitis, a new genus of grammitid ferns segregated from Lellingeria (Polypodiaceae)
TLDR
Stenogrammitis, a new genus of grammitid ferns, is segregated from Lellingeria based on morphological and molecular evidence and Lectotypifications are made for Grammitis muscosa, Polypodium itatiayense, P. oosorum var.
A new species of Thelypteris (Thelypteridaceae) from southern Bahia, Brazil
TLDR
A new species of Thelypteris beckeriana, endemic to the Atlantic Rain Forest of southern Bahia, Brazil, which belongs to subgenus Goniopteris because of the presence of forked and stellate hairs on some parts of its blades.
