A DNA barcode for land plants
The 2-locus combination of rbcL+matK will provide a universal framework for the routine use of DNA sequence data to identify specimens and contribute toward the discovery of overlooked species of land plants.
A classification for extant ferns
A revised classification for extant ferns is presented, with emphasis on ordinal and familial ranks, and a synopsis of included genera is provided, reflecting recently published phylogenetic hypotheses based on both morphological and molecular data.
Ferns diversified in the shadow of angiosperms
It is shown that polypod ferns (> 80% of living fern species) diversified in the Cretaceous, after angiosperms, suggesting perhaps an ecological opportunistic response to the diversification of angios perms, as angiosPerms came to dominate terrestrial ecosystems.
Phylogeny and evolution of ferns (monilophytes) with a focus on the early leptosporangiate divergences.
The phylogenetic structure of ferns (= monilophytes) is explored here, with a special focus on the early divergences among leptosporangiate lineages. Despite considerable progress in our
Horsetails and ferns are a monophyletic group and the closest living relatives to seed plants
It is shown that there are three monophyletic groups of extant vascular plants: (1) lycophytes, (2) seed plants and (3) a clade including equisetophytes (horsetails, psilotophytes) and all eusporangiate and leptosporangiates ferns.
A linear sequence of extant families and genera of lycophytes and ferns
A linear classification to the extant lycophytes and ferns based on current phylogenetic knowledge is provided, which provides a standardized guide for organisation of fern collections into a more natural sequence.
The timescale of early land plant evolution
A timescale for early land plant evolution that integrates over topological uncertainty by exploring the impact of competing hypotheses on bryophyte−tracheophyte relationships, among other variables, on divergence time estimation is established.
Chloroplast Phylogeny of Asplenioid Ferns based on rbcL and trnL-F Spacer Sequences (Polypodiidae, Aspleniaceae) and its Implications for Biogeography
A phylogenetic framework from which the historical biogeography of asplenioid ferns can be inferred for Europe and North America is presented, showing a separation of the deeper branches into tropical and temperate clades.
