A classification for extant ferns
A revised classification for extant ferns is presented, with emphasis on ordinal and familial ranks, and a synopsis of included genera is provided, reflecting recently published phylogenetic hypotheses based on both morphological and molecular data.
A community‐derived classification for extant lycophytes and ferns
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.
A subgeneric classification of Selaginella (Selaginellaceae).
A new classification of the lycophyte family Selaginellaceae is presented, based on a well-founded hypothesis of the evolutionary relationships of Selaginella, and each subgenus can be identified by a suite of morphological features possible to study in the field.

This work investigates the phylogenetic relationships of scaly tree ferns based on DNA sequence data from five plastid regions and concludes that indusium shape is homoplastic it does contain useful phylogenetic information that supports some of the larger clades recognised.
The evolutionary history of ferns inferred from 25 low-copy nuclear genes.
A curated phylogenomics approach is taken to infer the first broad fern phylogeny from multiple nuclear loci, by combining broad taxon sampling with focused character sampling, along with rigorous alignment, orthology inference and model selection.

Among the significant phylogenetic results is the near-complete support along the eupolypod II backbone, the demonstrated paraphyly of Woodsiaceae as currently circumscribed, and the well-supported placement of the enigmatic genera Homalosorus, Diplaziopsis, and Woodsia.
Phylogenetic relationships in Selaginellaceae based on RBCL sequences.
A phylogenetic framework is developed for the clubmoss family Selaginellaceae based on maximum parsimony analyses of molecular data that provides support for monophyly of subgenera Selaginella and Tetragonostachys and indicates a large number of new groupings not previously recognized on morphological grounds.
Tree ferns: monophyletic groups and their relationships as revealed by four protein-coding plastid loci.
Phylogeny of Selaginellaceae: There is value in morphology after all!
An overall well-supported phylogeny of Selaginella is presented, and the phylogenetic positions of some previously problematic taxa are now resolved with strong support, showing that even though the evolution of most morphological characters involves reversals and/or parallelisms, several characters are phylogenetically informative.
Plastid atpA data provide improved support for deep relationships among ferns
The atpA dataset had more variable characters and resulted in a more robustly supported phylogeny than any of the other single gene datasets examined, suggesting that at pA will be exceptionally useful in more extensive studies of fern phylogeny and perhaps also in studies of other plant lineages.
