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.

Infrageneric Revision of the Fern Genus Deparia (Athyriaceae, Aspleniineae, Polypodiales)
Systematic Botany, 2018Current molecular phylogenetic analyses support the monophyly and circumscription of the athyrioid fern genus Deparia (Athyriaceae), which includes previously recognized genera including Athyriopsis, ×Depazium, Dictyodroma, Dryoathyrium (= Parathyrium), Lunathyrium, and Neotriblemma (= Triblemma Ching), and ×Neotribleparia.

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.

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.

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.

Pteridryaceae: A new fern family of Polypodiineae (Polypodiales) including taxonomic treatments
Journal of Systematics and Evolution, 2018AbstractWe undertook phylogenetic analyses to resolve the relationships of Pteridrys and related taxa based on six plastid markers (atpA, atpB, matK & rps16‐matK, rbcL, rps4 & rps4‐trnS, and trnL & trnL‐F) and nuclear pgiC. We included 195 accessions representing approximately 147 species in 38 genera, and seven of the nine families in ...

Systematics of the Leptochilus macrophyllus complex (Polypodiaceae, Polypodiales)
Botanical Journal of the Linnean SocietyAbstract Leptochilus is an Old World fern genus with uncertain species diversity. The Leptochilus macrophyllus complex exemplifies this uncertainty, as previous taxonomic treatments recognized it as a broadly circumscribed species with considerable morphological variation.

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.
