Simultaneous diversification of Polypodiales and angiosperms in the Mesozoic

Cladistics, 2021
AbstractComprising about 82% of the extant fern species diversity, Polypodiales are generally believed to have diversified in the Late Cretaceous. We estimated the divergence times of Polypodiales using both penalized likelihood and Bayesian methods, based on a dataset consisting of 208 plastomes representing all 28 families and 14 fossil constraints ...

Palynology of selected species of Blechnaceae (Polypodiopsida: Polypodiales)

Palynology, 2021
The Blechnaceae is a family of leptosporangiate ferns with a wide geographical distribution. Recent phylogenies revealed several lineages within the family, culminating in a classification system c...

Revision of the fern genus Diplazium (Polypodiales: Athyriaceae) in Thailand

Phytotaxa, 2023
The genus Diplazium in Thailand is revised. Thirty-one species are recognized, of which D. thailandicum is new to science, and two species, D. bellum and D. pallidum are new to Thailand. These species are described and illustrated. The lectotypes of D. dilatatum, D. leptophyllum, D. petolotii and D. petrii are designated here.

Five long-distance dispersals shaped the major intercontinental disjunctions in Tectariaceae s.l. (Polypodiales, Polypodiopsida)

Molecular Phylogenetics and Evolution, 2023
Intercontinental disjunct distributions can arise either from vicariance, from long-distance dispersal, or through extinction of an ancestral population with a broader distribution. Tectariaceae s.l., a clade of ferns in Polypodiales with ca. 300 species mainly distributed in the tropics and subtropics, provide an excellent opportunity to investigate ...

Ultrastructure and composition of cell wall appositions in the roots of Asplenium (Polypodiales)

Micron, 2011
Cell wall appositions (CWAs), formed by the deposition of extra wall material at the contact site with microbial organisms, are an integral part of the response of plants to microbial challenge. Detailed histological studies of CWAs in fern roots do not exist.

Morphological characterization of infra‐generic lineages in Deparia (Athyriaceae: Polypodiales)

Cladistics, 2017
AbstractDeparia, including the previously recognized genera Lunathyrium, Dryoathyrium (=Parathyrium), Athyriopsis, Triblemma, and Dictyodroma, is a fern genus comprising about 70 species in Athyriaceae. In this study, we inferred a robust Deparia phylogeny based on a comprehensive taxon sampling (~81% of species) that captures the morphological ...

Systematics of the Adiantum philippense complex (Pteridaceae, Polypodiales) in Taiwan

Phytotaxa, 2016
Adiantum philippense s.l. is a member of once-pinnate Adiantum but comprise several cytotaxa with different ploidies and reproductive modes. According to the differences of cytotypes, the up-to-date revision had identified three subspecies under the A. philippense complex. In Taiwan, different ploidies and reproductive modes had also been found in this
