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… 
An Expanded Plastid Phylogeny of Tectaria (Tectariaceae), with Description of Four New Species from the Solomon Islands
An expanded phylogeny of Tectaria based on five plastid markers is presented, infer the systematic position of newly included species, providing insights to interspecific relationships of some species groups, and to determine the identity of some specimens with distinct morphology.
A Classification of the Fern Genus Tectaria (Tectariaceae: Polypodiales) Based on Molecular and Morphological Evidence1
This study synthesizes chloroplast and nuclear DNA evidence, morphology, and/or distribution information and divides Tectaria into four subgenera, which are divided into 16 generic names and four generic names are synonymized to individual infrageneric taxa.
The true Tectaria chinensis (Tectariaceae): morphology, distribution, and allied species
Tectaria chinensis is a poorly known species from China, with its type being an incomplete frond and the sole authentic voucher to date, and featured by the unique long and erect caudex and the rare combination of partly free venation and vein-dorsal sori.
New insights on the phylogeny of Tectaria (Tectariaceae), with special reference to Polydictyum as a distinct lineage
The genus Polydictyum is formally reinstate by providing diagnostic characters, key to species, nomenclature, and information of detailed distribution and habitat for the currently known three species of Tectaria.
A phylogenetic and morphological study of the Tectaria fuscipes group (Tectariaceae), with description of a new species
A new species found in southern China and Vietnam is described here as T. fungii, which is similar to the T. fuscipes complex and T. kusukusensis, but differs from the former mainly by its brown-castaneous lanceolate stipe scales and from the latter by having nearly hairless laminae.
Virtual issue: Ecology and evolution of pteridophytes in the era of molecular genetics
19 papers recently published in the Journal of Plant Research dealing with the biology of pteridophytes are compiled, grouped into six categories: breeding systems, species complexes and polyploidization, fossil taxa, gametophyte ecology, systematics, biodiversity, and biodiversity.

The past quarter–century has witnessed a revolution in the understanding of the phylogenetics, systematics, and ecology of pteridophytes (ferns and lycophytes), particularly due to the rapid accumulation of plastid sequence data and a renewed interest in the ecology of the sexual phase of the life cycle.


The fern genus Adenoderris (family incertae sedis) is artificial
A molecular analysis of the genus Adenoderris based on multiple chloroplast markers with the goal of placing its species phylogenetically, provide insights into its morphology and complex taxonomy, and make relevant nomenclatural changes are presented.
On the monophyly of subfamily Tectarioideae (Polypodiaceae) and the phylogenetic placement of some associated fern genera
Polypodiaceae subfamily Tectarioideae is hereby defined to include Arthropteris, Hypoderris, Pteridrys, Tectaria and Triplophyllum, which was found to be monophyletic.
Towards the natural classification of tectarioid ferns: Confirming the phylogenetic relationships of Pleocnemia and Pteridrys (eupolypods I)
The results showed that the monophyletic genus Pleocnemia belonged to the Dryopteridaceae and was not related to the Tectariaceae, as it had been in the past, and the placement of this genus into TECTariaceae was confirmed.
Didymochlaenaceae: A new fern family of eupolypods I (Polypodiales)
The study clearly showed that the family Didymochlaenaceae should be recognized and hereby validate this name previously proposed by Ching, and resolved Didym Cochlaena as sister to the rest of eupolypods I with strong support.
A linear sequence of extant families and genera of lycophytes and ferns
A linear classification to the extant lycophytes and ferns based on current phylogenetic knowledge is provided, which provides a standardized guide for organisation of fern collections into a more natural sequence.
Circumscription and phylogeny of the fern family Tectariaceae based on plastid and nuclear markers, with the description of two new genera: Draconopteris and Malaifilix (Tectariaceae)
Major results include: Tectaria as currently circumscribed is not monophyletic and can be divided into three genera, and it is advocated that Lomariopsidaceae include these four genera (plus the unsampled Thysanosoria); and intercontinental dispersal appears to have played an important role in shaping the extant distribution.
Polyphyly of the fern family Tectariaceae sensu Ching: insights from cpDNA sequence data
A narrowly monophyletic Tectariaceae is identified, which includes Ctenitopsis, Hemigramma, Pteridrys, Quercifilix, and Tectaria, and a working concept is proposed here that better reflects the inferred evolutionary history of this group.
The fern-genera Tectaria, Heterogonium and Ctenitis in the Mascarene Islands
A study of many recent collections in comparison with the more fragmentary older ones, resulting in revisions of specific concepts and of synonymy, describes new species and combinations of Ctenitis lorencei and C. canacae and new varieties.
Studies in the fern-genera allied to Tectaria. III. Aenigmopteris and Ataxipteris, two new genera allied to Tectaria Cav., with comments on Psomiocarpa Presl
Two new genera, Aenigmopteris and Ataxipteris, are established, based on a single species of southern China and Japan originally named Tectaria sinii Ching, and both genera lack the cylindric glands which are characteristic of Ctenitis.
