Pteris 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...
متن کاملChemical constituents of Pteris cretica Linn. (Pteridaceae)
1. Subject and Source The group of fern from the genus Pteris (Pteridaceae) contains 250 cosmopolitan species (Mabberley, 1997). One species, P. cretica (Japanese name: ohbano-inomotoso) called Cretan brake fern is widely distributed in the temperate and warm area of Japan. Although some fern members of the family Pteridaceae are well known to contain carcinogenic C-14 illudane-type sesquiterpe...
متن کاملExtreme Multiple Reticulate Origins of the Pteris cadieri Complex (Pteridaceae)
The Pteris cadieri complex displays extensive morphological variation and seems to have originated through hybridization. However, the members of this complex reproduce by apogamy, which usually limits genetic variation. To evaluate the hypotheses of hybrid origins, the pattern of evolution in this species complex is reconstructed. Multiple methodologies were used. Diploids, triploids, and tetr...
متن کاملGaga, 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 کاملCharacterization of arsenic-resistant endophytic bacteria from hyperaccumulators Pteris vittata and Pteris multifida.
We isolated and characterized As-resistant endophytic bacteria (AEB) from two arsenic hyperaccumulators. Their plant growth promoting traits and the relation between As tolerance and transformation were evaluated. A total of 41 and 33 AEB were isolated from Pteris vittata (PV) and Pteris multifida (PM) respectively. PV AEB represented 2genera while PM AEB comprised of 12 genera, with Bacillus s...
