SummaryFor a long time, the genus Metaxya was treated as monotypic with a single species, M. rostrata. A second species, M. lanosa, was described in 2001 on the basis of morphological features and rbcL gene sequences with a suggestion that the genus may contain even more species. We have now systematically compared morphological traits in a large number of Metaxya specimens collected in tropical America. We have also carried out phylogenetic analyses of 32 Metaxya and 5 outgroup specimens based… Expand
A community‐derived classification for extant lycophytes and ferns
A modern, comprehensive classification for lycophytes and ferns, down to the genus level, utilizing a community‐based approach, that uses monophyly as the primary criterion for the recognition of taxa, but also aims to preserve existing taxa and circumscriptions that are both widely accepted and consistent with the understanding of pteridophyte phylogeny.

Fern and lycophyte flora of Acre state, Brazil
This paper provides keys, illustrations, short descriptions, and voucher specimen citations for the ferns and lycophytes of Acre, Brazil. We recognize a total of 212 species in 66 genera and 28Expand
State of the art and perspectives on neotropical fern and lycophyte systematics
The current state of knowledge on fern and lycophyte systematics in the Neotropics is presented, and sampling sufficiency and current taxonomic and phylogenetic knowledge are emphasized. Expand
An inventory of the ferns and lycophytes of the Lower Tapajós River Basin in the Brazilian Amazon reveals collecting biases, sampling gaps, and previously undocumented diversity
Ferns and lycophytes are an excellent group for conservation and species distribution studies because they are closely related to environmental changes. In this study, we analyzed collection gaps,Expand
A free-access online key to identify Amazonian ferns
An internet-based free-access tool to identify Amazonian fern species, which includes 302 terrestrial and aquatic entities mainly from lowland Amazonian forests, developed in Lucid 3.5 software. Expand
Methylated Xanthones from the Rootlets of Metaxya rostrata Display Cytotoxic Activity in Colorectal Cancer Cells
The current investigation resulted in the isolation of the previously undescribed methylated xanthones, and the monomethylated derivatives showed qualitatively similar effects/mechanisms to their nonmethylated analogues, while dimethylation almost abolished the activity. Expand
Diversidad de los helechos y licófitos de Colombia
Se presenta el analisis de la diversidad de helechos y licofitos para Colombia, donde Andina es donde se presenta la mayor diversidad, 1199 especies incluidas en 142 generos, la region Caribe y the Orinoquia son las menos diversas. Expand


Molecular Phylogenetic Relationships and Morphological Evolution in the Heterosporous Fern Genus Marsilea
Using six plastid regions, a phylogeny for 26 species of the heterosporous fern genus Marsilea is presented, and it is suggested that the presence of an inferior sporocarp tooth and the place of sporocarps maturation are homoplastic characters, and are therefore of unreliable taxonomic use at an infrageneric level.

rbcL gene sequences provide evidence for the evolutionary lineages of leptosporangiate ferns.
To compare competing classifications, DNA sequences of a chloroplast gene were obtained and phylogenetic trees were inferred by the neighbor-joining and the parsimony methods that provided insights concerning major general evolutionary trends in the leptosporangiate ferns. Expand
Phylogenetic relationships of the enigmatic fern families Hymenophyllopsidaceae and Lophosoriaceae: Evidence fromrbcL nucleotide sequences
Both newly-examined families appear to be part of a previously characterized and well-supported clade of tree ferns, and a sister relationship between Lophosoria and Dicksonia and also between Hymenophyllopsis and Cyathea is supported. Expand
On the Phylogenetic Position of Cystodium: It's Not a Tree Fern – It's a Polypod!
The results strongly support including Cystodium within the large polypod clade, and suggest its close relationship to the species-poor grade taxa at the base of the polypod topology (Sphenomeris and Lonchitis, or Saccoloma in this study). Expand
Metaxya lanosa, a Second Species in the Genus and Fern Family Metaxyaceae
Metaxya lanosa is described and illustrated, the second known species in the genus and the fern family Metaxyaceae (Pteridophyta) and support for the recognition of at least two species within Metaxya is rejected. Expand
First insights into fern matK phylogeny.
The power of matK for fern phylogenetic reconstruction is demonstrated as well as primers that successfully amplify matK across all fern families and extensive sequence data that will greatly facilitate future evolutionary studies of ferns are provided. Expand
Tree ferns: monophyletic groups and their relationships as revealed by four protein-coding plastid loci.
The results show that Dicksoniaceae and Cyatheaceae, as currently recognised, are not monophyletic and new circumscriptions for these families are needed. Expand
Amplification of noncoding chloroplast DNA for phylogenetic studies in lycophytes and monilophytes with a comparative example of relative phylogenetic utility from Ophioglossaceae.
The relative phylogenetic utility of five cpDNA regions for resolving relationships in Botrychium s.l. (Ophioglossaceae) and lycophyte and monilophyte species was analyzed, with the strongest support for the inferred phylogeny coming from the trnS(GCU)-trnG(UUC) spacer+trnRpS4 intron region. Expand
Vascular tissue development in the mature stems of the six squamate genera of the Cyatheaceae is described, showing striking similarities in both anatomical and morphological characters, and constitute a natural grouping. Expand
Towards Resolving the Complete Fern Tree of Life
The most comprehensive fern phylogeny to date, representing over one-fifth of the extant global fern diversity, is inferred based on four plastid genes, demonstrating the power of using a ‘supermatrix’ approach to resolve large-scale phylogenies and reveal questionable taxonomies. Expand
