Welcome to this special issue of the Journal of Systematics and Evolution focused on the systematics and evolution of lycophytes and ferns. It is our hope that it will inspire innovative research on these plants at this critical time where human activities are transforming biodiversity as we know it. Lycophytes and ferns are distinct evolutionary lineages, with ferns strongly supported as sister to seed plants and lycophytes, in turn, sister to this large (euphyllophyte) clade. Notably, however… Expand

Studies on the complementary relationship of surface ornamentations between megaspores and microspores of Selaginella P. Beauv. (Selaginellaceae)
TLDR
The observations support the “synaptospory” hypothesis, that is, spore surface ornamentation plays a part in keeping or bringing spores together during their dispersal in the pteridophytes. Expand

Evolutionary Genomics of Ferns and Lycophytes
TLDR
This chapter reviews what is known about fern and lycophyte genomes (nuclear, chloroplast, and mitochondrial) and transcriptomes and presents an outlook on the future of genome research in these groups, including outstanding challenges in plant biology that will be illuminated by incorporating information on ferns and Lycophytes. Expand
State of the art and perspectives on neotropical fern and lycophyte systematics
TLDR
The current state of knowledge on fern and lycophyte systematics in the Neotropics is presented, and sampling sufficiency and current taxonomic and phylogenetic knowledge are emphasized. Expand
Biology and Evolution of Ferns and Lycophytes
TLDR
Biology and Evolution of Ferns and Lycophytes fills a major gap in biological, organism-level, evolutionary literature by providing a review of the biology and evolution of this important group of vascular land plants. Expand
What do we know about Hawaiian ferns and lycophytes?
TLDR
Most of the available literature on Hawaiian ferns and lycophytes is reviewed, finding that research has been conducted on a wide range of topics including systematics, floristics, dispersal, phylogeny, biogeography, ecology, form and function, population genetics, microevolution, fern‐animal and f Fern‐fungi associations, reproductive biology, demography, ethnobotany, and conservation.

Pteridophyte fungal associations: Current knowledge and future perspectives
TLDR
A critical review of current knowledge of fungal associations across pteridophytes is provided and future directions making recommendations along the way are considered, finding the best conclusion that can be reached is that the fungal symbionts of pterids belong to the two fungal lineages Mucoromycotina and Glomeromycota. Expand
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. Expand
A current perspective on apomixis in ferns
TLDR
This review provides a synopsis of apogamous reproduction in ferns and highlights important progress made in recent studies of fern apomixis, highlighting a shift in focus from the observation and characterization of apomIXis in f Ferns to more integrated studies of the evolutionary and ecological implications of this reproductive mode. Expand
The ghost of the Cretaceous terrestrial revolution in the evolution of fern–sawfly associations
TLDR
The observed phylogenetic patterns are consistent with the hypothesis of “larval diet conservatism” resulting in the establishment of genera and lineages that feed exclusively, or at least predominantly, on conifers, eudicots, ferns, and monocots. Expand

TLDR
It is now understood that (1) homosporous vascular plants are genetically diploid at high chromosome numbers and (2) both heterOSporous and homosporaous plants store and release genetic variation through a similar range of breeding systems. Expand
Exploring the pteridophyte flora of the Eastern Afromontane biodiversity hotspot
TLDR
This is the first comprehensive attempt to assess the pteridophyte diversity of the East African mountains providing the framework for future studies on their conservation, ecology, and evolution. Expand
