Metaxya lanosa, a Second Species in the Genus and Fern Family Metaxyaceae

  title={Metaxya lanosa, a Second Species in the Genus and Fern Family Metaxyaceae},
  author={Alan R. Smith and Hanna Tuomisto and Kathleen M Pryer and Jeffery S. Hunt and Paul G Wolf},
Abstract We describe and illustrate Metaxya lanosa, the second known species in the genus and the fern family Metaxyaceae (Pteridophyta). It is currently known from four different watersheds in Amazonian Peru and Venezuela. It can be distinguished readily from M. rostrata by the noticeably woolly-hairy stipes and rachises (hairs red-brown or orange-brown and easily abraded), broader, more elliptic pinnae, cartilaginous and whitish pinna margins, more distinct veins abaxially, and longer pinna… Expand
Newly discovered diversity in the tropical fern genus Metaxya based on morphology and molecular phylogenetic analyses
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 andExpand
Erratum to: Newly discovered diversity in the tropical fern genus Metaxya based on morphology and molecular phylogenetic analyses
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. Expand
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. Expand
Wedocument 137 species of pteridophytes new to the flora of Peru since the pubUcation of the previous flora by Tryon and Stolze, in 1994. Some of these are recently described species (but no newExpand
Assessing phylogenetic relationships in extant heterosporous ferns (Salviniales), with a focus on Pilularia and Salvinia
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. 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
A classification for extant ferns
We present a revised classification for extant ferns, with emphasis on ordinal and familial ranks, and a synopsis of included genera. Our classification reflects recently published phylogeneticExpand
Fern phylogeny inferred from 400 leptosporangiate species and three plastid genes
The scope of the analysis provides unprecedented insight into overall fern relationships, not only delivering additional support for the deepest leptosporangiate divergences, but also uncovering the composition of more recently emerging clades and their relationships to one another. Expand
Species richness, endemism, and conservation of American tree ferns (Cyatheales)
Analyses of richness and endemism of Cyatheales (tree ferns) in tropical America were performed and evidence of a diversity gradient is presented. For this, the occurrence ranges of 239 species wereExpand
New Compounds from the Tree Fern Metaxya rostrata C . Presl
Four new natural compounds, namely 2-deprenyl-7-hydroxy-rheediaxanthone B, (2E)-2-(hydroxyl hexyliden)-cyclopropyl-1→3-diglucoside and (6E)-6[2-(β-glucopyranosyloxy)-cyclopropyliden] hexanoic acidExpand


rbcL data reveal two monophyletic groups of filmy ferns (Filicopsida: Hymenophyllaceae).
The results confirm the monophyly of the family and provide robust support for two monophyletic groups that correspond to the two classical genera and show that some taxa of uncertain affinity are convincingly included within Hymenophyllum s.l. Expand
A Molecular Assessment of Relationships Among Cryptic Species of Botrychium Subgenus Botrychium (Ophioglossaceae)
Phylogenetic relationships among 20 currently recognized species of Botrychium sub- genus Botrychium were investigated using nucleotide sequences from the plastid gene rbcL. Anal- ysis of eightExpand
Identification of the Juveniles of Some Ferns from Western Amazonia
In floristic inventories and ecological studies it is often desirable to collect and identify all individuals of the plants involved. This is necessary if the total number of individuals is to beExpand
An analysis of relationships within the Cupressaceae sensu stricto based on rbcL sequences.
The analysis of rbcL sequences of representative species of 13 of the 20 genera of the Cupressaceae sens. str. has produced a cladogram that agrees with data derived from other sources. The monophylyExpand
Non-Molecular Phylogenetic Hypotheses for Ferns
Ideas on the phylogenetic relationships of ferns are summarized, as based on evidence derived from such traditional sources as fossils, comparative morphology, anatomy, and chromosome number. Expand
Phylogenetic relationships of dennstaedtioid ferns: evidence from rbcL sequences.
Relationships among genera and families of dennstaedtioid ferns are clarified, and phylogenetic analysis of rbcL sequence data suggests relationships of some problematical genera, such as Monachosorum, Calochlaena, and Lonchitis. Expand
Molecular systematics and a revised taxonomy of the onocleoid ferns (Dryopteridaceae: Onocleeae).
Tree topologies of the onocleoid ingroup under maximum parsimony and maximum likelihood were completely congruent, and the previously recognized varieties of Onoclea sensibilis are supported at least at varietal rank and possibly at the rank of species. Expand
Phylogenetic relationships of extant ferns based on evidence from morphology and rbcL sequences
The first cladistic analysis of extant ferns based on morphological characters is presented, showing the value of using both molecular and morphological data sets in combination as well as separately, and bootstrap support for the leptosporangiate fern clades is much greater using the combined data set than when either the morphological or the molecular data set is analyzed separately.

Choosing an Approach and an Appropriate Gene for Phylogenetic Analysis
This chapter provides a general review of the various molecular techniques currently available to the plant systematist and discusses the advantages and disadvantages of each and the most appropriate approach for studying a given taxonomic level or type of evolutionary question. Expand
