p>The article discusses the species independence of Polystichum subtripteron Tzvel. The spore structure and size of 2 closely related species – P. subtripteron and P. tripteron were studied. Morphological differences of fronds fit into the overall range of variation; there are no differences in the spore external structure. DNA fragment analysis (I...

... In recent years RAF has been sufficiently applied to value the genetic diversity and interpopulational relations in plants (Cunningham et al. 2002;Ramage et al. 2004;Nand et al. 2005;Chan et al. 2008;Kutsev et al. 2013a, b;Kreshchenok et al. 2016). For example, RAF supported to confirm the division of Cassia brewsteri (F.Muell.) ...
This article presents the results of population-genetic analysis in four populations of Tanacetum vulgare (typical tansy) from Southern Siberia on the basis of the Randomly Amplified DNA Fingerprints (RAF). We used RAF to find certain molecular-genetic differences between the typical tansy and the northern tansy. Since the present results did not show any clear differences between the typical tansy and the northern tansy at species level, we suggest that T. vulgare includes two subspecies: the typical T. vulgare subsp. vulgare and T. vulgare subsp. boreale.
The taxonomic composition of the Polypodiophyta of the Russian Far East was processed more than 30 years ago. There was a need to revise the taxonomic composition of this group of plants, the systematic position of its representative species, taking into account recent research. The taxonomic composition of the Dryopteridaceae family was specified. Dryopteridaceae is the largest family of Polypodiophyta in the flora of Russia and the Russian Far East. It showed that in the Russian Far East, the family is represented by 4 genera and 17 species.
