“…The topology of Tectaria and allied genera produced in this study is generally consistent with those in previous studies (e.g., Ding et al, ; Zhang et al, ). One major difference is on the position of Arthropteris , for which we comment later.…”

“…In comparison, the hypothesis placing Arthropteris as sister to all tectarioids is more possible because this relationship was based on much more complete datasets (most samples with all target sequences available) and received moderate to strong support in BI, ML, and MP analyses, for example, with PP = 0.98–1.00 in this and previous studies (e.g., Ding et al, ; Liu et al, ; Wang et al, ), MLBS = 75–76% in Schuettpelz & Pryer () and in Ding et al () and being more than 95% in Liu et al (), and MPBS = 100% in Wang et al (). The hypothesis placing Arthropteris within tectarioids produced by Zhang et al (, ) seems less possible because there were quite a few missing data in their dataset, the combined sequences used to construct the phylogeny included both plastid and nuclear markers, which have different evolutionary history, and the node supporting this hypothesis received relatively low support (PP = 0.87, MLBS = 84–85%, and MPBS < 50%). Furthermore, as mentioned by Liu et al (, ) and by Ding et al (), the great divergences in morphology (especially the different number of vascular bundles in stipe) do not support the close affinity of Arthropteris to tectarioid ferns.…”

The fern genus Tectaria (Tectariaceae) Cav. is morphologically diverse and difficult in terms of recognizing species and species groups. To infer the systematic positions of some species and identity‐unknown collections with special morphological characters, we undertook phylogenetic analyses based on sequences of five plastid regions (atpB, ndhF + ndhF‐trnL, rbcL, rps16‐matK + matK, and trnL‐F). Three analysis methods (maximum parsimony, maximum likelihood, and Bayesian inference) were used to reconstruct the phylogeny of Tectaria. The most surprising result is that T. menyanthidis (C. Presl) Copel., T. ternata (Baker) Copel., and T. variabilis Tardieu & Ching are revealed to represent a distinct lineage from Tectaria, which should be called Polydictyum C. Presl, and is supported as sister to Pteridrys C. Chr. & Ching. Other accessions of Tectaria are well resolved into four major clades, which is consistent with the results of previous studies. Of the four clades, Clade II (T. subtriphylla (Hook. & Arn.) Copel. group) is unpredictable, with morphologically very diverse species clustered there, and is supposed to be a minor evolutionary line within Tectaria in the Old World. In addition, the position of the climbing genus Arthropteris J. Sm. and the utility of molecular data in recognizing species of Tectaria are briefly discussed. As a conclusion, we formally reinstate the genus Polydictyum by providing diagnostic characters, key to species, nomenclature, and information of detailed distribution and habitat for the currently known three species.

“…Phylogenetic studies have recovered conflicting hypotheses concerning the phylogenetic relationships of Pteridrys to other tectarioid ferns which arguably reflect the difficulties encountered to identify the phylogenetic lineages constituting this fern clade. Based on plastid atpB and rbcL genes, Liu et al () identified an unresolved trichotomy containing Arthropteris , Pteridrys , and Tectaria (including three other segregates of Tectaria : Ctenitopsis , Hemigramma , Quercifilix ; Ding et al, ; Zhang et al, ) and placed the two sinus‐teeth bearing genera, Pleocnemia and Pteridrys , hypothesized as being closely related to each other by Holttum (), in Dryopteridaceae and Tectariaceae, respectively. The Tectariaceae ( Pteridrys + Tectaria ) excluding Arthropteris sensu Liu et al () were not resolved as monophyletic by them.…”

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.

End of an enigma: Aenigmopteris belongs in Tectaria (Tectariaceae: Polypodiopsida)

The phylogenetic affinities of the fern genus Aenigmopteris have been the subject of considerable disagreement, but until now, no molecular data were available from the genus. Based on the analysis of three chloroplast DNA regions (rbcL, rps16-matK, and trnL-F) we demonstrate that Aenigmopteris dubia (the type species of the genus) and A. elegans are closely related and deeply imbedded in Tectaria. The other three species of genus are morphologically very similar; we therefore transfer all five known species into Tectaria. Detailed morphological comparison further shows that previously proposed diagnostic characters of Aenigmopteris fall within the range of variation of a broadly circumscribed Tectaria.
