Fern Phylogeny Based on rbcL Nucleotide Sequences

A revised generic classification of vittarioid ferns (Pteridaceae) based on molecular, micromorphological, and geographic data

“…These plants, characterized by the presence of silica bodies (Sundue, 2009) but a lack of sclerenchyma (Bower 1928;Ruhfel & al., 2008), were long regarded as composing a distinct family-Vittariaceae (Ching, 1940;Tryon & Tryon, 1982;Kramer, 1990). However, phylogenetic analyses have demonstrated that these ferns nest well within the Pteridaceae Hasebe & al., 1995;Prado & al., 2007;Schuettpelz & al., 2007), as sister to the genus Adiantum L. (Lu & al., 2012;Rothfels & Schuettpelz, 2014;Pryer & al., 2016).…”

New combinations in the fern genus Tectaria (Tectariaceae) for the Flora of China

“…Molecular studies (e.g. Hasebe et al 1995) have greatly increased the understanding of the placement of many genera and has redefined genera in Tectariaceae. Currently the family is considered to be composed of ca 10 genera (Aenigmopteris, Arthropteris, Heterogonium, Hypoderris, Pleocnemia, Psammiosorus, Psomiocarpa, Pteridrys, Tectaria and Triplophyllum).…”

“…The genera Ataxipteris, Ctenitis, Dryopsis and Lastreopsis, previously associated with Tectariaceae, are now considered to belong to the Dryopteridaceae (Smith et al 2006), and Liu et al (2007) also placed Pleocnemia tentatively in that family. Arthropteris and Psammiosorus form a group sister to the rest of Tectariaceae (Hasebe et al 1995), and for this reason are placed there (Liu et al 2007), even though this makes the family difficult to define morphologically (Smith et al 2006). Genera such as Amphiblestra, Camptodium, Chlamydogramme, Cionidium, Ctenitopsis, Dictyoxiphium, Fadyenia, Hemigramma, Pleuroderris, Pseudotectaria Tectaria sagenioides (Mett.)…”

Phylogeny of the Fern Genus Melpomene (Polypodiaceae) Inferred from Morphology and Chloroplast DNA Analysis

“…Molecular phylogenetic analyses including representative placeholder taxa have revealed the composition of, and the relationships among, the major leptosporangiate lineages (Hasebe & al., 1993(Hasebe & al., , 1995Pryer & al., 1995Schneider & al., 2004c;Vangerow & al., 1999;Wikström & Pryer, 2005;Wolf, 1996Wolf, , 1997. Densely sampled analyses within some of these groups have elucidated more detailed associations and have provided a phylogenetic framework for more narrowly-focused evolutionary studies (see references cited under various taxonomic groups in Discussion).…”
