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...

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 ...

Low‐copy nuclear data confirm rampant allopolyploidy in the Cystopteridaceae (Polypodiales) [PDF]

open access: yesTaxon, 2014
AbstractHere we present the first nuclear phylogeny for Cystopteridaceae (Polypodiales), using the single‐copy locusgapCp“short”. This phylogeny corroborates broad results from plastid data in demonstrating strong support for the monophyly of the family's three genera—Cystopteris, Acystopteris, andGymnocarpium—and of the major groups withinCystopteris ...
