“…(Gaertner, 1770: 539) s.l., are difficult to segregate due to lack of distinct generic characteristics and the prevalence of intergeneric hybrids. Elymus, the largest genus in the tribe Triticeae, consists of about 226 taxa worldwide and most of which are caespitose, linear-spiked perennial species, which were previously treated under Agropyron sensu lato (Tzvelev, 1973). Melderis (1978a) studied both the genera and expanded the genus Elymus by including the genera, that is, Roegneria K. Koch, Elytrigia Desv.…”

“…is one of the most widespread species of the genus Elymus L. in Northern Eurasia. Its habitat covers all of Europe from Iceland and the Mediterranean to the Urals Mountains, almost all, Palearctic parts of Siberia and some areas of Central Asia (Tzvelev, 1976; Hultén & Fries, 1986). In northern Europe, it is common everywhere in Sweden and Denmark, getting slightly less common in Norway and Finland.…”

We represent a comparative analysis of GBSS1 gene fragment sequences for a number of species related to Elymus caninus: Elymus prokudinii, Elymus viridiglumis, Elymus goloskokovii, as well as a number of morphologically deviating biotypes, inhabiting Russia and Kazakhstan. Microevolutionary relationships between species were assessed from dendrograms derived from sequences of exons and introns. In all taxa, the St subgenome was represented by St2 variants, rather typical of the North American ancestral line of Pseudoroegneria spicata than of the Asian line descending from Pseudoroegneria strigosa. All putative relatives of E. caninus had H1 subgenome variants linked around the Asian diploid carrier of the H genome from Hordeum jubatum and were divided into two subclades. One of them (H1‐1) contained most of the closely related E. caninus clones, including Elymus uralensis. Another subclade (H1‐2) consisted of five variants phylogenetically related to Elymus mutabilis. We have also studied reproductive relationships between species E. goloskokovii, E. prokudinii, and E. viridiglumis and the degree of their integration into the E. caninus complex. Biotypes included in sexual hybridization formed a single recombination gene pool, within which slight differences in reproductive compatibility were observed. A comprehensive study of microevolutionary differentiation of taxa showed the expediency of taxonomic revision. The species mentioned should probably be relegated to the infraspecific rank within E. caninus s. l.

“…Thus, lampoon flowers with yellow flowers were of the perianth narrow wedge-shaped leaflets to the base used to designate P. uralensis. The P. patens are characterized by a blue-violet (different saturation) color of the perianth, wider lobes of leaf plates (Tzvelev 2001(Tzvelev , 2012Egorova et al 2017). In common habitats, these species form transitional populations with intermediate trait values (Figure 1) (Sushencov 2007).…”

Abstract. Aidarkhanova GS, Kubentayev SA, Kukhar YV, Urazalina AS. 2022. Current state of populations, resources, and biological activity Pulsatilla patens (Ranunculaceae) in Northern Kazakhstan. Biodiversitas 23: 2311-2320. Pulsatilla (Ranunculaceae Juss.) is one of the complex groups in systematic and nomenclature terms, which has more than 30 taxa. Pulsatilla species are widely used against many pathologies. Anti-inflammatory, antibacterial, antifungal, antimicrobial, antimalarial, and antitumor properties of these plants are known. The object of our research was Pulsatilla patens (L.) Mill. (Ranunculaceae) from the allopathic complex P. patens with yellow flower color in the Northern regions of Kazakhstan. The article provides detailed information on environmental and biological features, morphology, geographical distribution, phylogenetic characteristics, and raw materials of P. patens in Northern Kazakhstan. In addition to these studies, the antimicrobial and fungicidal activity of extracts from leaves and roots of the species is shown. It was established that the species grows in 6 administrative regions of Central and Northern Kazakhstan and 7 floristic regions. In the studied region, P. patens are often found along rocky foothill terraces (mainly on the southern slopes), forest edges, along the southern slopes and tops of the hills of steppes, and among shrubs. Data on the study of P. patens biomorphology showed that quantitative parameters are characterized by the greatest intra- and inter-population variability CV (number of individuals per 1 m2 (38-69%); the number of basal leaves (44-61%); the number of generative shoots per bush (32-53%). Metric parameters such as height during flowering (17-27%), height during fruiting (12-18%), flower diameter (14-24%), leaf blade diameter (11-26%) are characterized by low and medium variability, both within the population and at the inter-population level. In the phenological aspect, the species begins to grow in the first half of April. Blooms from mid-April to early May. Bears fruit from the second half of May to early June. The complete end of vegetation falls at the end of September. Analysis of biological activity of stem extracts and leaves of P. patens of Kazakhstan population showed that they have pronounced fungicidal properties in relation to conditionally pathogenic yeast Candida parapsilosis and molds Aspergillus niger. Water decoction P. patens was also active against Escherichia coli, indicating that it has antibacterial properties.
