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...

Pteris vittata L. is very common and a widely distributed species belongs to the family Pteridaceae. Various cytotypes from diploid octaploid available in this fern species. The present work has been carried out for genetic diversity both within between cytotypes. molecular analysis at inter- as well intra-species with 57 accessions of P. other Microsorium punctatum considered an group taxon. F...

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...

The essential oils of water-distilled aerial parts of Anthemis pseudocotula and Anthemis cretica subsp. pontica (Asteraceae) were analysed by GC-MS. As a result thirty-five and forty compounds were identified representing 93.1% and 89.0% of the oils, respectively. The main compounds of A. pseudocotula were 1,8-cineole (39.40%), camphor (9.36%), artemisiaketone (5.68%), filifolene (5.15%), and a...

Demographic parameters of the pink stem borer, Sesamia cretica Lederer (Lepidoptera: Noctuidae) were estimated on its two main host plants, maize and sugarcane. The present study was conducted under laboratory conditions at 27±1 ̊C, 50±10% Relative Humidity (RH %), and a photoperiod of 0:24 (L:D) hour for the larval stage and 16:8 (L:D) hour for the other life stages. The raw data were analyzed ...

The objective of this paper was to investigate the inhibitory effect of total flavonoids from Pteris multifida Poir on growth of transplanted H22 tumour in mice. H22 tumour-bearing mice model was established; the experimental animals were divide/d into the model group, Pteris multifida Poir total flavonoids high-, low-dose groups, and CTX group. Pteris multifida Poir groups were administered co...

Background and objectives: The main aims of this study have been finding out the antibacterial activity and preliminary phytochemical screening of some fern species. Methods: The antimicrobial activity of the methanol extracts of Polypodium interjectum Shivas, Polystichum woronowii Fomin, Polystichum aculeatum (L.) Roth., Dryopteris affinis (Lowe) Fraser-Jenk...
