( F. x souliei ) in Europe (Gutiérrez Villarías et al, 1992 ); F. polesica and F. arundinaceae , Festuca × polovina in Ukraine (Bednarska, 2009 ); Festuca rubra and Vulpia myuros in Italy (Ardenghi et al, 2011 ); F. galiciensis × F. rupicola in Ukraine (Bednarska & Brazauskas, 2017 ). Thus, the complex genetic structure in this group brings difficulties with the proper taxonomic identification of specimens.…”

“…For instance, F. valesiaca is diploid and hexaploid (Arndt, 2008;Probatova et al, 2008;Šmarda, 2008;Šmarda et al, 2005), while F. rupicola and F. pseudovina are hexaploids (Alexeev et al, 1988;Šmarda et al, 2005). Whereas, samples of a hybrid origin may have the same or different ploidy levels in comparison with parental species (Bednarska & Brazauskas, 2017). Subcluster C consists of F. albifolia, F. borissii, F. kryloviana, F. kurtschumica, F. tschujensis, and F. saurica species that are characterized by leaf sheaths closed for ¼-⅘ of its length and three sclerenchyma strands.…”

“…Interspecific hybridization is another quite frequent phenomenon that is observed in fine‐leaved fescues and plays an important role in species formation within the genus Festuca (Ardenghi et al, 2011 ; Bednarska, 2009 ; Bednarska & Brazauskas, 2017 ; Gutiérrez Villarías et al, 1992 ). The taxonomical difficulties in Festuca are the result of the morphological similarity of species, and the identification of hybrids based on morphological and anatomical characters is very hard, especially in complexes of closely related and morphologically similar taxa.…”

Additionally, it has been estimated that approximately 70% of fescue taxa are polyploids with a wide range of ploidy levels, spanning from diploid to dodecaploid species (Bednarska & Brazauskas, 2017; Dubcovsky & Martinez, 1992; Hunziker & Stebbins, 1987; Šmarda, 2006; Šmarda et al, 2005; Šmarda & Stancik, 2006).…”

Festuca is one of the largest genera within the Poaceae family. Molecular phylogenies demonstrate that Festuca s.l. comprises two groups: broad‐ and fine‐leaved species. The latter is the species‐richest and taxonomically complicated group due to being paraphyletic. Here, we provide the first insight into the phylogeny of 17 fine‐leaved species of Altai fescues. Based on genome‐wide genotyping, the examined taxa were divided into three markedly differentiated clusters. The first cluster comprises species from the F. rubra complex, the second cluster includes the F. brachyphylla complex, and the third cluster contains taxa from the groups F. ovina , F. valesiaca , and F. kryloviana . Importantly, we detected a complex genetic pattern within the groups of F. valesiaca and F. kryloviana . Moreover, our findings underline a discrepancy between morphological and molecular data for some species distributed within the Altai Mountain Country. We suggest that in order to validate the current findings on the fine‐leaved fescues, additional comprehensive research including morphological, karyological, and molecular methods is required. Nonetheless, our work provides a baseline for further investigations on the genus and studies on the floral diversity of Asia.

River riparian ecosystems deteriorate because of anthropogenic factors that are related to industry, intensive agriculture and tourism. Two native species, Bidens tripartita and B. cernua, are weeds widespread in Lithuania on river banks and other habitats. An alien species, B. frondosa, is also widespread in the same habitats. We investigated the genetic diversity of B. frondosa, compared its population structure to that of related species and assessed the possibility of genetic interaction between B. frondosa and native congeners. Genetic analysis of populations was based on inter-simple sequence repeats (ISSR) polymorphism. Our results revealed high genetic differentiation in the B. frondosa populations (48.2%) and high genotypic diversity (i = 0.99). Bayesian cluster analysis using the program Structure revealed signs of gene flow between B. frondosa and the native species; however, principal coordinate analysis did not support this result. Our results do not indicate the role of interspecific hybridization in the invasiveness of B. frondosa.

As a result of monographic studies of taxonomy of the genus Festuca in the flora of Central Europe, a specialized herbarium collection of the genus was established on the base of LWKS. The key peculiarity of the collection is the populational approach to the material. As of today, about 600 population sample groups with 20-30 specimens in each are stored, which total approximately 15 000 plants. The collection represents diversity patterns in populations (mostly narrow-leaved fescue species) in various geographical areas and allows analyzing the peculiarities of species differentiation anatomically and morphologically in different ecological conditions, in natural and anthropogenically disturbed habitats, in cultivation, and even under weather and climatic changes in different years.
