A genus-wide molecular phylogeny for Polystichum and allied genera (Dryopteridaceae) was reconstructed to address the biogeographic origin and evolution of the three Hawaiian Polystichum species, all endemic there. The analysis was based on the cpDNA sequences rbcL and the trnL-F spacer from a taxonomically and geographically diverse sample. Parsimony and Bayesian phylogenetic analyses of the combined data support a monophyletic Polystichum and corroborate recent hypotheses as to membership and…

Phylogeny and biogeography of exindusiate Andean Polystichum (Dryopteridaceae).
TLDR
The monophyletic exindusiate Andean Polystichum lineage diverged from a Mexican lineage in the middle Miocene and diversified in the central Andes before dispersing northward, corresponding with episodes of uplift in the tropical Andes.
Using a multilocus phylogeny to test morphology-based classifications of Polystichum (Dryopteridaceae), one of the largest fern genera
TLDR
DNA sequences of five plastid loci of 177 accessions representing ca.
Phylogeny of Chinese Polystichum (Dryopteridaceae) based on chloroplast DNA sequence data (trnL-F and rps4-trnS)
TLDR
Three subclades resolved within Polystichum sensu stricto (s.s.) clade do not correspond with recent sectional classifications, and it is outlined the issues relevant to a new classification for the genus.
Global phylogeny and biogeography of the fern genus Ctenitis (Dryopteridaceae), with a focus on the Indian Ocean region.
Molecular Phylogenetic Relationships of Cibotium and Origin of the Hawaiian Endemics
TLDR
Molecular phylogenetic analyses supported Hawaiian Cibotium as monophyletic, suggesting a single colonization of the Hawaiian Islands, and suggest the trade winds or storms that delivered spores from Mesoamerica or theHawai'i Islands were colonized first by a species from Asia, followed by subsequent dispersal to MesoAmerica from Hawai'i.
Speciation and Reticulation in the Polystichum Allotetraploids of the Costa Rican Cordillera Talamanca
TLDR
Evidence that the páramo tetraploid most recently named as Polystichum orbiculatum is derived from two distinct Andean progenitors is found, and the Costa Rican polyploids incorporate the legacy of the Andean and Mayan regions into their genomes, forming new lineages with novel genotypes.
Historical biogeography of the fern genus Deparia (Athyriaceae) and its relation with polyploidy.
Biogeographic disjunction between eastern Asia and North America in the Adiantum pedatum complex (Pteridaceae).
TLDR
The eastern Asian-North American disjunction in the complex is inferred to be the result of two intercontinental migrations, one from eastern Asia into North America in the late Tertiary and the other from North America back to eastern Asia in the Pleistocene.

Asian origin for Polystichum (Dryopteridaceae) based on rbcL sequences
TLDR
The phylogenetic and divergence time estimation results lead us to suggest that Polystichum s.l. originated in Asia in the late Late Cretacous and migrated into other places in the world in early Eocene.
Major evolutionary events in the origin and diversification of the fern genus Polystichum (Dryopteridaceae).
TLDR
Examining rbcL sequences and morphological characters from 55 fern taxa suggests that the common ancestor of Polystichum s.s.l. and Phanerophlebia had evolved the common features of the alliance, including ciliate petiole-base scales, once-pinnate fronds, ultimate segments with scarious tips, peltate indusia, and microscales.

Origin of the Hawaiian endemic mints within North American Stachys (Lamiaceae).
TLDR
It is hypothesize that the Hawaiian mints may be polyploid hybrids whose reticulate genomes predate the Hawaiian dispersal event and are derived from Stachys lineages with flowers exhibiting insect- vs. bird-pollination characteristics.
Origin of the endemic fern genus Diellia coincides with the renewal of Hawaiian terrestrial life in the Miocene
TLDR
It is suggested that the ancestor of the Diellia lineage may have been among the first successful colonists of the newly emerging islands in the archipelago and is consistent with a recent rapid radiation.
Molecular Phylogeny of the Polystichoid Ferns in Asia Based on Rbcl Sequences
TLDR
Morphologically, once-pinnate leaf dissection and reticulate venation appear to be ancestral in the polystichoid ferns.
Phylogenetics of the genus Scaevola (Goodeniaceae): implication for dispersal patterns across the Pacific Basin and colonization of the Hawaiian Islands.
TLDR
Analyses of ITS sequence data demonstrate that Scaevola is a monophyletic group if S. collaris is excluded and Diaspasis filifolia is included, and indicates that three of the six dispersals established species on the remote Hawaiian Archipelago, representing at present the largest number of colonizations by any flowering plant genus to these islands.
Chloroplast DNA evolution and systematics of Phanerophlebia (Dryopteridaceae) and related fern genera.
TLDR
Reticulate venation, previously considered an important taxonomic character for infrageneric classification in Phanerophlebia, most likely evolved independently twice within the genus.
