The monogeneric Daphniphyllaceae contain 36 taxa in the genus Daphniphyllum Blume that are endemic to Southeast Asia. is a morphologically homogeneous group of evergreen shrubs trees divided into three sections: Daphniphyllum, Lunata T. C. Huang, and Staminodia Hurusawa. While medicinal value has been explored many studies, understanding their evolutionary history infrageneric classification st...

phytoplankton taxa composition of the caspian sea were evaluated by using samples collected at 12 stations along the iranian coast of the caspian sea between 1996 and 2010. this study identified 158 phytoplankton species consisted of diatoms (70 species), dinoflagellates (23 species), chlorophytes (29 species), cyanophytes (31 species), and euglenoids (5 species). the dominant species were the ...

The phylogeny of the genera traditionally classified in the family Pluteaceae (Agaricales, Basidiomycota) was investigated using molecular data from nuclear ribosomal genes (nSSU, ITS, nLSU) and consequences for taxonomy and character evolution were evaluated. The genus Volvariella is polyphyletic, as most of its representatives fall outside the Pluteoid clade and shows affinities to some hygro...

The current classification of what used to be called Catapyrenium comprises eight genera belonging to distinct lineages in the Verrucariaceae. Previous phylogenetic studies have shown that the redefined genus Catapyrenium (Catapyrenium s. str.) is monophyletic and sister of Placidiopsis within the Staurothele group, but this relationship was based on only two species from each genus. We conduct...

a total of 90 species, belonging to 29 genera and 15 families, observed from an urban wetland of meghalaya is the species-rich rotifera assemblage known till date from any sub-tropical ecosystem of the indian sub-region. total richness (s) merits biodiversity value as ~56.0, ~ 38.0 and ~23.0 % of the species recorded from meghalaya, northeast india (nei) and india, respectively while several ro...

Analysis of sequence data from the chloroplast gene ndhF identifies at least 12 major well-supported clades within the genus Solanum. These are briefly described, given informal clade names, and compared with the groups recognized by previous Solanum workers. Non-molecular synapomorphies are proposed for many of the clades. Continued use of informal taxonomic designations is advocated for new i...
