A new fossil record of Lindsaeaceae (Polypodiales) from the mid-Cretaceous amber of Myanmar
Cretaceous Research, 2020Abstract A new fossil belonging to the Lindsaeaceae is described as Proodontosoria myanmarensis gen. et sp. nov. from the mid-Cretaceous Myanmar amber. Its classification in the extant Lindsaeaceae is based on laterally fused vein tips that bear sori, indusia opening toward the segment margins, and trilete spores.

The fern Rumohra ponceana sp. nov., a narrow endemic of the Austral Pampean district, Pampean biogeographic province in Argentina, is described and illustrated. The species inhabits the Tandilia and Ventania Systems, where it grows in sunny rock crevices. The new species differs from the widespread R.

Systematics of the Adiantum philippense complex (Pteridaceae, Polypodiales) in Taiwan
Phytotaxa, 2016Adiantum 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

Antrophyum nambanense, A New Vittarioid Fern (Pteridaceae; Polypodiales) From Vietnam
Systematic Botany, 2020Abstract—A new species, Antrophyum nambanense, is described here based on the evidence from morphology and molecular phylogeny. Morphologically, short taeniform soral paraphyses and large fronds are the diagnostic characteristics of A. nambanense. Phylogenetically, it is most closely related to A.

Asplenium pifongiae (Aspleniaceae: Polypodiales), a New Species from Taiwan
Systematic Botany, 2016Abstract We describe and illustrate a new species, Asplenium pifongia., currently known only from Taiwan. Although superficially similar to A. monanthe., this species is a sexual diploid and has little perforation on its spore surfaces. Phylogenetic analyses demonstrate that A. pifongia. is not closely related to A.

Diversity, endemism and conservation of ferns (Polypodiales) in the Mexican Mountain Component
Journal of Mountain Science, 2015We analyzed the distributional patterns of 95 selected species of leptosporangiate ferns inhabiting the Mexican Mountain Component, using grid-cells of one geographical degree as unit areas, applying endemism indices and richness and beta diversity analyses. Distributional data were obtained from several herbaria and specialized literature.

The fern family Blechnaceae, with about 250 species, has traditionally comprised one large genus, Blechnum, plus seven to nine smaller genera, most with fewer than 10 species. Several phylogenetic analyses strongly suggest that Blechnum in the traditional sense is not a monophyletic group.

AbstractBlechnaceae, a leptosporangiate fern family nested within eupolypods II, comprises 200–250 species, typically divided among seven to nine genera. Despite recent molecular studies of the family, it still lacks a modern taxonomic update based on broad sampling from the two centres of diversity—the Neotropics and Australasia/Oceania.
