Toward a community-derived classification for lycopods and ferns.

Phylogeny has long informed pteridophyte classification and, as our ability to infer evolutionary trees has improved, classifications aimed at recognizing natural groups have become increasingly predictive and stable. The ordinal and familial classification of ferns by Smith et al. (2006), which was founded on the principle of monophyly, but also recognized the importance of maintaining established names, has been generally well-received by the pteridological community. However, over the past decade, important advances have been made in our understanding of relationships, which were not accounted for in this or subsequent classifications. To this end, we proposed the establishment of a Pteridophyte Phylogeny Group (PPG) tasked with updating the classification of lycopods and ferns following the main tenets of Smith et al. (2006), but utilizing a community-based approach. Here, we present a summary of progress to date and our vision for the future.
