“…At the family level, 28 Chinese pteridophyte families recognized by Ching's classification (Ching, ) are not recognized and/or supported by molecular evidence. These families are now considered to be part of broadly defined families (Table ; see also table S1 of Zhang & Gilbert, ), for example, Adiantaceae in Pteridaceae (Schuettpelz et al, ), Bolbitidaceae in Dryopteridaceae (Liu et al, ; Zhang et al, ), Botrychiaceae in Ophioglossaceae (Hauk et al, ), and Loxogrammaceae in Polypodiaceae (Schneider et al, ); some of them correspond to well‐supported phylogenetic lineages, such as Botrychiaceae to the Botrychium clade of the Ophioglossaceae (Hauk et al, ; Williams & Waller, ; Shinohara et al, ). Dryopteridaceae, Polypodiaceae, and Pteridaceae are three examples where circumscription has been expanded in both species number and morphological disparity compared to Ching's treatments.…”

The phylogenetic relationships of pteridophytes occurring in China were reconstructed using DNA sequences of the three plastid genes, atpA, atpB, and rbcL. The sampling comprised all genera of Chinese pteridophytes-including ferns and lycophytes-with the exception of four small genera. The effort to sample all recorded families and genera in a phylogenetic framework enabled the phylogenetic relationships of all Chinese pteridophytes to be addressed for the first time in a single phylogenetic hypothesis. The results provided strong evidence to support the continuing impact of Ren-Chang Ching's integrative classification of pteridophytes. Ten out of 11 orders accepted by Ching were consistent with the phylogeny, whereas four new orders were introduced to avoid paraphyletic taxa in the leptosporangiate ferns. Of the 63 families considered by Ching, 36 families were supported by molecular data, 22 of those had the same or nearly the same circumscription, and the remaining 14 families were supported but substantially revised. Twenty-eight small families were now accepted as synonyms. A consistent pattern was observed at the generic level. Among the 223 genera considered by Ching, 133 genera were recognized by the phylogeny, although some of them were substantially changed in the context of circumscription, and 90 were now accepted as synonyms. Three endemic genera were incorporated here for the first time in DNA-based phylogenetic analyses, namely Blechnidium, Saxiglossum, and Sinephropteris, which were shown to be nested in Blechnum, Pyrrosia, and Asplenium respectively. This paper tentatively accepts 40 families and 151 genera of ferns and lycophytes occurring in China; the importance of phylodiversity of Chinese pteridophytes is also briefly discussed.

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.
