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 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 کاملAdetogramma (Polypodiaceae), a new monotypic fern genus segregated from Polypodium
Polypodiaceae is one of the most diverse and abundant families of ferns in tropical and subtropical forests. Despite multiple studies investigating its phylogeny and taxonomy, several generic boundaries within the family still need clarification. One of the most problematic circumscriptions is that of Polypodium L., and one species that still contributes to this uncertainty is Polypodium chryso...
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 کاملPteris latipinna sp. nov. (Pteridaceae), a new species segregated from Pteris fauriei
Pteris fauriei is widely distributed in Eastern Asia and has high morphological variation. Some morphologically similar plants related to this species are difficult to distinguish. We showed that the new Pteris species from Taiwan, previously identified as P. fauriei, can be morphologically distinguished by its wide pinnae, larger terminal pinnae than the lateral pinnae in sterile fronds, and t...
