Gaga, a New Fern Genus Segregated from Cheilanthes (Pteridaceae)
Ongoing molecular phylogenetic studies of cheilanthoid ferns confirm that the genus Cheilanthes (Pteridaceae) is polyphyletic. A monophyletic group of species within the hemionitid clade informally called the “C. marginata group” is here shown to be distinct from its closest relatives (the genus Aspidotis) and phylogenetically distant from the type species of Cheilanthes. This group is here seg...
متن کاملA New Triterpene Acid from the Fern Notholaena grayi

متن کاملTryonia, a new taenitidoid fern genus segregated from Jamesonia and Eriosorus (Pteridaceae)
The Neotropical fern genera Eriosorus and Jamesonia have long been thought of as close relatives. Molecular phylogenetic studies have confirmed this notion but have also revealed that neither genus is monophyletic with respect to the other. As a result, all known species of Eriosorus were recently subsumed under the older generic name Jamesonia. Here, through an analysis of a four-gene plastid ...
متن کاملPhytotaxa 7: 52–59 (2010) The new fern genus Calciphilopteris (Pteridaceae)
A new genus of Pteridaceae subfamily Cheilanthoideae is established for what has long been known as Doryopteris ludens. The newly erected genus is named Calciphilopteris in reference to its substrate specificity to limestone. Calciphilopteris can be found throughout Southeast Asia, from Indo-China to New Guinea and Australia. New combinations are established for the four known species (Calciphi...
متن کاملA synopsis of the genus Rheum (Polygonaceae) in Iran with description of three new species
According to previous studies, the genus Rheum in Iran includes four species: R. turkestanicum Janisch., R. persicum Losinsk., R. ribes L. and R. khorasanicum Baradaran & Jafari. During the long-term study, based on field and many herbaria specimens, three new species including R. iranshahrii Taheri & Assadi sp. nov., R. kordestanicum Taheri & Assadi sp. nov. and R. austro-iranicum Taheri & Ass...
