“…In the combined analysis, H. decurrens grouped with T. decurrens/subtriphylla, but this relationship was poorly supported (BS<50%, PP<90%). Traditionally, both Hemigramma and Quercifilix were considered as derivatives of Tectaria [1,7,31] , or even reduced to synonyms of the latter [32,33] . However, morphological characteristics, especially dimorphic fronds and acrostichoid sori clearly separated both genera from Tectaria.…”

Polyphyly of the fern family Tectariaceae sensu Ching: insights from cpDNA sequence data

Tectariaceae are a pantropical fern family of about 20 genera, among which 8 are distributed in China. The morphological distinctiveness of the family is widely recognized, yet relatively little systematic research has been conducted on members of Tectariaceae. Phylogenetic analyses of chloroplast DNA sequence data (rbcL and atpB) from 15 species representing all 8 genera in China were carried out under parsimony criteria and Bayesian inference. The phylogenetic reconstructions indicated that the fern family Tectariaceae as traditionally circumscribed are polyphyletic. Ctenitis, Dryopsis, Lastreopsis clustered with and should be included within the newly-defined Dryopteridaceae, and Pleocnemia is also tentatively assigned to it. A narrowly monophyletic Tectariaceae is identified, which includes Ctenitopsis, Hemigramma, Pteridrys, Quercifilix, and Tectaria. In the single rbcL analysis, Arthropteris clustered with the above-mentioned monophyletic Tectariaceae. Although further investigations are still needed to identify infrafamilial relationships within the monophyletic Tectariaceae and to redefine several problematic genera, we propose a working concept here that better reflects the inferred evolutionary history of this group.

We undertook phylogenetic analyses to resolve the relationships of Pteridrys and related taxa based on six plastid markers (atpA, atpB, matK & rps16‐matK, rbcL, rps4 & rps4‐trnS, and trnL & trnL‐F) and nuclear pgiC. We included 195 accessions representing approximately 147 species in 38 genera, and seven of the nine families in Polypodiineae (eupolypods I). Tectariaceae s.l. (i.e., Arthropteris, Draconopteris, Hypoderris, Malaifilix, Pteridrys, Tectaria, and Triplophyllum in addition to Polydictyum) is recovered as monophyletic (97% maximum likelihood bootstrap value), but with low (<50%) maximum parsimony jackknife value. The family Tectariaceae s.l. is therefore the only family in ferns without a corresponding non‐parametric‐based strong support in spite of our data totaling 9616 aligned base pairs. Tectariaceae s.l. can not be unambiguously recognized by any of the 13 morphological characters analyzed. However, if the clade composed of Draconopteris, Malaifilix, Polydictyum, and Pteridrys (DMPP) is recognized as a distinct family, at least four morphological characters enable the distinction of the DMPP clade from its sister clade. Considering the uncertainty in the monophyly, the diagnosability, and the deep divergence, we propose to establish a new family, Pteridryaceae, to accommodate the DMPP clade. Species of Pteridryaceae share mostly the following characteristics: erect to suberect rhizomes, reduced basal pinnae, anastomosing or free venation, absence of catenate hairs at the leaf surface, and perine ornamentation lacking spines or spinules. Identification keys are provided for the four genera and 31 species of the DMPP clade (or Pteridryaceae). Reflecting the presented results, the recognition of Arthropteridaceae is the preferred taxonomic status of the Arthropteris clade.

Abstract-Ferns are the second largest group of vascular land plants after the angiosperms, but remain chronically underrepresented in studies of plant phylogeny, biogeography, physiology, and genomics. The genus Dryopteris, the woodferns, is a large group with a worldwide distribution, and recent research has made it one of the better understood fern genera and a potential model for understanding many aspects of fern biology and evolution. Here we review historical and current understanding of the genus, and outline promising avenues of future research in ferns for which Dryopteris is an ideal study system, particularly for research on polyploid complexes, biogeographic distributions, and physiological ecology.
