“…The dataset characteristics are presented in Table 1. Comparisons of tree topologies from the MLBS analyses of the individual markers did not identify any wellsupported conflicts (JK ≥ 70%; Zhang & Simmons, 2006;Zhang & al., 2012Le Péchon & al., 2016b;Zhou & al., 2016) except for the positions of Tectaria draconoptera (D.C.Eaton) Copel. : the eight plastid datasets combined resolved this species as sister to T. grandidentata (Ces.)…”

The circumscription and the phylogeny of the fern family Tectariaceae have been controversial. Previous molecular studies have supported the monophyly of this family, with 4–5 genera. However, these studies were exclusively based on plastid markers and relatively small sampling, especially of the non‐Tectaria genera. In the present study, DNA sequences of eight plastid and one nuclear markers of 25 accessions representing 19 species of Tectaria and 58 accessions representing ca. 90% of the non‐Tectaria species in the family (including Arthropteris) were used to infer a phylogeny using maximum likelihood (ML), Bayesian inference, and maximum parsimony. Our major results include: (1) Tectaria as currently circumscribed is not monophyletic and can be divided into three genera: Tectaria s.str., Draconopteris (gen. nov.) from Central to South America, and Malaifilix (gen. nov.) from Malesia; (2) Draconopteris and Malaifilix, the two new genera, together with Pteridrys, form a strongly supported clade; (3) in our ML analyses, the clade containing Draconopteris, Malaifilix, and Pteridrys (the DMP clade) is resolved as sister to the rest of Tectariaceae and Arthropteris is sister to Tectaria + (Hypoderris + Triplophyllum), suggesting that Arthropteris should be treated as a member of Tectariaceae, and thus Tectariaceae contains seven genera: Arthropteris, Draconopteris, Hypoderris, Malaifilix, Pteridrys, Tectaria, and Triplophyllum; (4) with the well‐supported relationships among the members of Tectariaceae, anastomosing venation in the family is inferred to have evolved independently at least three times; (5) Nephrolepis is strongly supported as sister to a clade containing Cyclopeltis, Dracoglossum, and Lomariopsis, and thus we advocate that Lomariopsidaceae include these four genera (plus the unsampled Thysanosoria); and (6) intercontinental dispersal appears to have played an important role in shaping the extant distribution of Tectariaceae.

“…Preliminary MP analyses conducted on the five individual plastid regions yielded similar tree topologies (trees not shown). There was no conflict between well-supported clades (P70% JK or BS support; Mason-Gamer and Kellog, 1996;Zhang and Simmons, 2006;Zhang et al, 2012Zhang et al, , 2016Zhou et al, in press) in the individual analyses and thus the five plastid regions were combined into one dataset comprising 190 taxa and 3346 characters (Table 3).…”

“…A comparison of the trees resulting from MPJK analyses of the individual plastid markers and the combined plastid dataset did not identify any well-supported conflicts in MP analyses (MPJK ! 70%; MasonGamer and Kellogg, 1996;Zhang and Simmons, 2006;Zhang et al, 2015Zhang et al, , 2016Zhou et al, 2016). The five plastid markers were therefore concatenated and analyzed in unison.…”
