A New Species of &lt;I&gt;Microgramma&lt;/I&gt; (Polypodiaceae) from Brazil and Recircumscription of the Genus Based on Phylogenetic Evidence

Phylogeny has long informed pteridophyte classification. As our ability to infer evolutionary trees has improved, classifications aimed at recognizing natural groups have become increasingly predictive and stable. Here, we provide a modern, comprehensive classification for lycophytes and ferns, down to the genus level, utilizing a community‐based approach. We use monophyly as the primary criterion for the recognition of taxa, but also aim to preserve existing taxa and circumscriptions that are both widely accepted and consistent with our understanding of pteridophyte phylogeny. In total, this classification treats an estimated 11 916 species in 337 genera, 51 families, 14 orders, and two classes. This classification is not intended as the final word on lycophyte and fern taxonomy, but rather a summary statement of current hypotheses, derived from the best available data and shaped by those most familiar with the plants in question. We hope that it will serve as a resource for those wanting references to the recent literature on pteridophyte phylogeny and classification, a framework for guiding future investigations, and a stimulus to further discourse.

This paper provides keys, illustrations, short descriptions, and voucher specimen citations for the ferns and lycophytes of Acre, Brazil. We recognize a total of 212 species in 66 genera and 28 families. Of these, the lycophytes are represented by 14 species, 4 genera, and 2 families, and the ferns by 8 varieties, 1 subspecies, 198 species, 62 genera, and 26 families. The total represents an increase of 22 species and two varieties compared to a checklist published in 2009. The six most species-rich genera are Adiantum (21 spp.), Asplenium (14), Selaginella (12), Trichomanes (11), Lindsaea, and Microgramma (9 each). None of the species treated here are endemic to Acre. A new combination is made for Meniscium chrysodioides Fée var. goyazense.

For ferns and lycophytes, the Neotropics is a hotspot of diversity (3000-4500 species), and second only to Southeastern Asia in richness and endemism. This paper presents the current state of knowledge on fern and lycophyte systematics in the Neotropics, and emphasizes sampling sufficiency and current taxonomic and phylogenetic knowledge. Plant systematics plays an important role in documenting diversity and geographic distribution patterns that are needed to understand relationships and evolutionary patterns, and a vital role in species conservation. Although in recent decades this field of science has undergone a revolution because of new approaches and techniques, data presented in this work shows that large gaps remain and there is still a long path towards fully understanding fern and lycophyte systematics in Neotropics. Approaches and how to choose areas that should be targeted in order to try to fulfill these knowledge gaps are discussed.
