The infrageneric relationships and taxonomy of the largest fern genus, Asplenium (Aspleniaceae), have remained poorly understood. Previous studies have focused mainly on specific species complexes involving a few or dozens of species only, or have achieved a large taxon sampling but only one plastid marker was used. In the present study, DNA sequences from six plastid markers (atpB, rbcL, rps4, rps4‐trnS, trnL and trnL‐F) of 1030 accessions (616 of them newly sequenced here) representing c. 420… 
Backbone phylogeny of Lepisorus (Polypodiaceae) and a novel infrageneric classification based on the total evidence from plastid and morphological data
The results herein show that Lepisorus is monophyletic when Neolepisorus, Lemmaphyllum, Tricholepidium, Neocheiropteris and Lepidomicrosorium are included, as well as Lepisurus jakonensis and Paragramma.
Root anatomy of 37 species of Asplenium (Aspleniaceae) from Argentina: Contributions to the systematics and phylogeny of the genus
In order to assess the potential use of root features in the taxonomy and the phylogenetic relationships within Asplenium, the roots of the 37 species inhabiting Argentina were studied and only in few instances the root subtypes were shared by closely phylogenetically related species.

Abstract. The classification and typification of all Australian ferns and lycophytes is updated to reflect the Pteridophyte Phylogeny Group I classification and the International Code of Nomenclature
Genetic variation and phylogeography of the Australian and New Zealand fern Asplenium flabellifolium (Aspleniaceae)
Haplotypes and morphological features were not found to be exclusive to either breeding system or ploidy and no taxonomic revision is proposed, indicating possible long-term persistence in these areas of Australia and New Zealand.
Transcriptomic Evidence of Adaptive Evolution of the Epiphytic Fern Asplenium nidus
Genes involved in stress responses and photosynthesis were found to have undergone positive selection in A. nidus, especially in the ANR1 subclade of MADS-box family genes which played roles in lateral root development.
Taxonomic revision of the Asplenium wrightii complex (Aspleniaceae) with reinstatement of A. alatulum and A. subcrenatum
A taxonomic revision of the three species of Asplenium in this complex from Asia is carried out, revealing that A. alatulum and A. subcrenatum, previously treated as synonyms of A. wrightii, should be reinstated.
Character expression, reproductive barriers, and origin of the rare fern hybrid Asplenium ×aran-tohanum (Aspleniaceae)
Asplenium ×aran-tohanum appears to be an evolutionary dead end, probably formed recurrently at the places where it grows, but incapable of completing its life cycle or producing viable offspring.
Biotic Interactions between the Gametophytes of Wall Rue (Asplenium ruta-muraria) and Other Fern Species
It is concluded that the sample of A. ruta-muraria does not use antheridiogens and may be able to affect the growth of other gametophytes by other means, possibly via allelopathy, although this aspect ofgametophyte interaction is poorly understood.
Looking Back on 130 Years of Fern and Lycophyte Research in Glacier National Park, Montana: A Modern Taxonomic Account
Abstract. Glacier National Park encompasses over one million acres in the mountains of northwestern Montana, along the United States–Canada border. Our survey of online databases indicates that the
Asplenium quangbinhense sp. nov. and three new records of Asplenium (Aspleniaceae) from Vietnam
A new species of Asplenium (Aspleniaceae) from Vietnam is described as A. quangbinhense, and a morphological comparison is presented between the two species.


A global plastid phylogeny uncovers extensive cryptic speciation in the fern genus Hymenasplenium (Aspleniaceae).
The fern genus Hymenasplenium (Aspleniaceae) is one of the two genera in the family. It is generally recognized among modern pteridologists. However, its infrageneric relationships and species
Phylogenetic relationships of two Cuban spleenworts with unusual morphology: Asplenium (Schaffneria) nigripes and Asplenium pumilum (Aspleniaceae, leptosporangiate ferns)
It is proposed to treat Schaffneria as a synonym of Asplenium and adopt the name Asplenic nigripes, which is placed sister to A. pumilum, the only species of AsPlenium with whitish catenate hairs on its leaves.
A global plastid phylogeny of the brake fern genus Pteris (Pteridaceae) and related genera in the Pteridoideae
DNA sequences of six plastid loci of 146 accessions representing 119 species of Pteris and 18 related genera were used to infer a phylogeny using maximum‐likelihood, Bayesian‐inference and maximum‐parsimony methods.
Chloroplast Phylogeny of Asplenioid Ferns based on rbcL and trnL-F Spacer Sequences (Polypodiidae, Aspleniaceae) and its Implications for Biogeography
A phylogenetic framework from which the historical biogeography of asplenioid ferns can be inferred for Europe and North America is presented, showing a separation of the deeper branches into tropical and temperate clades.
A revised family-level classification for eupolypod II ferns (Polypodiidae: Polypodiales)
We present a family-level classification for the eupolypod II clade of leptosporangiate ferns, one of the two major lineages within the Eupolypods, and one of the few parts of the fern tree of life
Phylogeny of the fern family Aspleniaceae in Australasia and the south-western Pacific
This study supports the current taxonomic practice of recognising two genera, Asplenium L. and Hymenasplenium Hayata, in Aspleniaceae, and identifies future taxonomic work required for the family in this region, including potential synonymising of species, and revision of species complexes or widespread species that are demonstrably non-monophyletic.
Species diversity and reticulate evolution in the Asplenium normale complex (Aspleniaceae) in China and adjacent areas
The results support the hypothesis that A. normale s.l. contains several species and outline an improved species classification recognizing three diploid and four tetraploid entities.
Phylogenetic and biosystematic relationships in four highly disjunct polyploid complexes in the subgenera Ceterach and Phyllitis in Asplenium (Aspleniaceae)
Phylogenetic studies using DNA sequences of two chloroplast regions demonstrate that the proposed genus Ceterach is a small clade within the large genus Asplenium, and sister to the Phyllitis clade, which suggests that leaf blades with dense indumenta have evolved at least twice within asplenioid ferns.

Global phylogeny and biogeography of grammitid ferns (Polypodiaceae).
Grammitid ferns are a well-supported monophyletic group with two biogeographically distinct lineages: a primarily Neotropical grade exhibiting several independent successful colonizations to the Afro-Malagasy region and a primarily Paleotropical clade exhibiting multiple independent dispersals to remote Pacific islands and temperate, austral regions.
