Typification of a Linnaean name in Gleicheniaceae (Polypodiopsida)

Phytotaxa, 2018
Gleicheniaceae are an ancient fern family with about 157 species and six genera (PPG I 2016). Although its taxonomy has been through several changes in the last years (Gonzales & Kessler 2011), a great gap remains in both taxonomy and nomenclature.

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

Journal of Plant Research, 2017
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.

Molecular Phylogeny and Recircumscription of the Fern Genus Pecluma (Polypodiaceae–Polypodiopsida)

Phytotaxa, 2016
To evaluate the monophyly of the genus Pecluma, molecular data from species of Pecluma, members of the Polypodium dulce group, Phlebodium and other Polypodiaceae genera were analysed. The molecular study was based on four plastid regions, rps4+rps4–trnS, trnL–F, matK, and rbcL, and included sequences of 30 species of Pecluma (75% of the genus).

A Plastid Phylogeny of the Cosmopolitan Fern Family Cystopteridaceae (Polypodiopsida)

Systematic Botany, 2013
Abstract Among the novel results of recent molecular phylogenetic analyses are the unexpectedly close evolutionary relationships of the genera Acystopteris, Cystopteris, and Gymnocarpium, and the phylogenetic isolation of these genera from Woodsia. As a consequence, these three genera have been removed from Woodsiaceae and placed into their own family,

One forgotten name, and another misinterpreted, in Lomariocycas (Blechnaceae, Polypodiopsida)

Phytotaxa, 2018
Blechnaceae Newman (1844: 8) is a subcosmopolitan family of leptosporangiate ferns (Polypodiopsida), which comprises around 250 species (Pteridophyte Phylogeny Group 2016). Until recently, most of this diversity fell under one, large genus Blechnum Linnaeus (1753: 1077), but after the accumulation of strong evidence of its non-monophyletic status ...
