Hymenasplenium inthanonense (Aspleniaceae), A New Fern Species from Doi Inthanon, and its Phylogenetic Status

  title={Hymenasplenium inthanonense (Aspleniaceae), A New Fern Species from Doi Inthanon, and its Phylogenetic Status},
  author={Kunio Iwatsuki and Jun Yokoyama and Noriaki Murakami},
A new species of Aspleniaceae, Hymenasplenium inthanonense N. Murak. et J. Yokoy. was described from Doi Inthanon, Tha iland . This species is closely re lated to  H. cheilosorum , but can be distinguished by it more medial sorus position and less dimidiate pinnae. It is readily recognizable even in mixed populations by its morphological, cytological, ecological and molecular characters. The relatively large (about 10 base pairs) difference in the s lowly evolving rbcL gene between H… Expand
Molecular α-Taxonomy of a Morphologically Simple Fern Asplenium nidus Complex from Mt. Halimun National Park, Indonesia
This work made a detailed analysis of the genetic variation of A. nidus in one locality, Mt. Halimun National Park, West Java, Indonesia, and found good correlation among rbcL types, some morphological characters and ecological traits, especially for morphologically simple organisms like ferns.

Molecular systematics of the Asplenium nidus complex from Mt. Halimun National Park, Indonesia: evidence for reproductive isolation among three sympatric rbcL sequence types.
The results suggest that three rbcL sequence types of A. nidus are cryptic species because they are reproductively isolated but they are difficult to distinguish morphologically. Expand
Allozyme analysis of cryptic species in the Asplenium nidus complex from West Java, Indonesia
The view that the five rbcL sequence types found in West Java are potential cryptic species is supported because they were genetically differentiated in allozymes that are encoded in their nuclear genomes. Expand
A Reassessment of the Little-Known Amazonian Fern Diplazium praestans Based on Molecular and Morphological Evidence
Abstract Family- and genus-level circumscription of ferns in the suborder Aspleniineae (eupolypods II) has long been controversial, due in part to confusion about the relationship among the familiesExpand
Cryptic species in the fern Ceratopteris thalictroides (Parkeriaceae). III. Referential diagnostic characters of three cryptic species

Three cryptic species of Ceratopteris thalictroides, named the south type, the north type and the third type, were examined for their morphological characteristics, using sporophytes cultivated under common conditions, finding the following characters to be effective for identifying the three types: the relative lengths of stipe to blade and to pinna, the degree of dissection, and the segment densities.

Adaptive evolution of rbcL in Conocephalum (Hepaticae, bryophytes).
An excess of nonsynonymous substitutions over synonymous ones has been regarded as an important indicator of adaptive evolution or positive selection at the molecular level. We now report such a caseExpand
Phylogenetic Placements of Loxoscaphe thecifera (Aspleniaceae) and Actiniopteris radiata (Pteridaceae) Based on Analysis of rbcL Nucleotide Sequences
It is indicated that there is presently no phylogenetic justification for accepting Loxoscaphe as a genus independent of Asplenium, and Actiniopteris radiata is robustly grouped with two Onychium species in a clade sister to traditional taenitidoids and deeply separated from the cheilanthoids, supporting affinities previously suggested by spore morphology.

Towards a stable nomenclature for Thai ferns
There have been many changes to family and genus delimitation in Thai ferns since the publication of volume 3 (Pteridophytes) of the Flora of Thailand and current names for all taxa, including those recently described or recorded for Thailand, are presented. Expand
Genetic Analysis of the Newly Found Diploid Cytotype of Deparia petersenii (Woodsiaceae: Pteridophyta): Evidence for Multiple Origins of the Tetraploid
It is concluded that the tetraploid D. petersenii has evolved from the diploid at least twice, which is a new cytotype the authors discovered in Taiwan. Expand
