Molecular Phylogenetic Relationships and Morphological Evolution in the Heterosporous Fern Genus Marsilea

Abstract Using six plastid regions, we present a phylogeny for 26 species of the heterosporous fern genus Marsilea. [] Key Result Two well-supported groups within Marsilea are identified. Group I includes two subgroups, and is relatively species-poor. Species assignable to this group have glabrous leaves (although land leaves may have a few hairs), sporocarps lacking both a raphe and teeth, and share a preference for submerged conditions (i.e., they are intolerant of desiccation).

A Plastid Phylogeny of the Cosmopolitan Fern Family Cystopteridaceae (Polypodiopsida)
- Biology, Environmental Science
- 2013
This work assembles a three-locus plastid dataset (matK, rbcL, trnG-R) that includes most recognized species in the Cystopteridaceae and multiple accessions of widespread taxa from across their geographic ranges, and yields the first species-level phylogeny of the family and the first molecular phylogenetic evidence for species boundaries.
Taxonomy and evolutionary history of the neotropical fern genus Salpichlaena (Blechnaceae)
- BiologyBlumea - Biodiversity, Evolution and Biogeography of Plants
- 2019
This work systematically documented 62 morphological traits in 283 herbarium specimens and sequenced 52 Salpichlaena specimens, suggesting that a group of specimens, placed into different clades in the plastid and nuclear trees and showing mixed morphological characters, represent a fourth species of hybrid origin.
An Expanded Plastid Phylogeny of Marsilea with Emphasis on North American Species
- Biology, Environmental Science
- 2012
DNA/morphology discordance suggests that these taxa either may have hybridized extensively or that the number of Marsilea species within these clades may be overestimated, which warrants the addition of nuclear data sets and reevaluation of the species boundaries within the genus.
Newly discovered diversity in the tropical fern genus Metaxya based on morphology and molecular phylogenetic analyses
- BiologyKew Bulletin
- 2016
Based on the morphological variation among the Metaxya specimens, the authors accept six distinct species, three of which are described as new in this paper, which are considered true species despite the incomplete genetic differentiation.

A Unified Approach to Taxonomic Delimitation in the Fern Genus Pentagramma (Pteridaceae)

Combining spore studies with phylogenetic analyses of plastid and nuclear sequences, this study identifies six genetically and morphologically distinct diploid lineages in Pentagramma, each of which is here treated as a species.
Assessing phylogenetic relationships in extant heterosporous ferns (Salviniales), with a focus on Pilularia and Salvinia
- Biology

These individual species-level investigations for Pilularia and Salvinia, together with previously published studies on Marsilea and Azolla, provide phylogenies within all genera of heterosporous ferns.
A molecular phylogeny of scaly tree ferns (Cyatheaceae).
- Biology, Environmental ScienceAmerican journal of botany
- 2007
This work investigates the phylogenetic relationships of scaly tree ferns based on DNA sequence data from five plastid regions and concludes that indusium shape is homoplastic it does contain useful phylogenetic information that supports some of the larger clades recognised.
Species Relationships and Farina Evolution in the Cheilanthoid Fern Genus Argyrochosma (Pteridaceae)
- Biology
- 2011
This reconstruction is used to examine the evolution of farina (powdery leaf deposits), which has played a prominent role in the circumscription of cheilanthoid genera, and indicates that Argyrochosma comprises two major monophyletic groups: one exclusively non-farinose and the other primarily farinose.
Molecular phylogeny, character evolution, and biogeography of the grammitid fern genus Lellingeria (Polypodiaceae).
- BiologyAmerican journal of botany
- 2010
It is suggested that Lellingeria is monophyletic, with two clades that are easily characterized morphologically and biogeographically and a small clade previously considered in Terpsichore should be recognized as a new genus.
