The genus Stipa is one of the largest genera of Poaceae. The phylogeny of the genus is still poorly resolved, and one of the main problems is linked to the extensive inter and intrasectional hybridization. Disclosure of hybridization processes is a key to understanding relationships between species within the genus. During a floristic study in feathergrass steppe ecosystems of central Asia, we found challenging specimens of Stipa with an interesting combination of morphological characters suggesting their origination through hybridization between morphologically and phylogenetically distant species. To confirm our hypothesis, we applied a combination of classical morphological and genome-wide SNP genotyping methods. Using such an approach, we determined that the new taxon named Stipa × smelanskyi arose from crossing S. richteriana and S. drobovii and confirmed that it is an F1 hybrid. Moreover, we found a S. drobovii specimen with a minor admixture of S. richteriana loci that may indicate putative introgression events among these taxa.

This paper presents the chromosome numbers (2n) for 13 alien species (from the families Apocynaceae, Asteraceae, Brassicaceae, Fabaceae, Lamiaceae, Polygonaceae, Solanaceae) in the Novosibirsk Region. For Vincetoxicum hirundinaria Medik. (2n = 22) and Sisymbrium altissimum L. (2n = 14), chromosome numbers were determined for the first time on the material from Russia; for Betonica officinalis L. (2n = 16) – from Asian Russia; for Stachys annua (L.) L. (2n = 34) – from West Siberia. Chromosome numbers on the material from the Novosibirsk Region were revealed for the first time for Cosmos bipinnatus Cav. (2n = 24), Inula helenium L. (2n = 20), Sonchus oleraceus L. (2n = 18), Medicago sativa subsp. varia(Martyn) Arcang. (2n = 32), Rumex obtusifolius L. (2n = 20) and Solanum nigrum L. (2n = 48). For all the species studied, brief notes on their general distribution and dispersal in the Novosibirsk Region are provided, along with literature data on chromosome numbers from other regions of Russia.

The classification of forests in the Bolshoy Agul river basin (Eastern Sayan) was developed using the Brawn-Blanquet method and cluster analysis. Two zonal forests categories in North Asia – boreal forests of the Vaccinio–Piceetea Br.-Bl. in Br.-Bl. et al. 1939 and hemiboreal forests of the Rhytidio–Laricetea Korotkov et Ermakov 1999 were revealed. Boreal coniferous forests are represented dominantly by two orders of the East Siberian-Mongolian type – Ledo–Laricetalia Ermakov et Alsynbayev 2004 and Lathyro–Laricetalia Ermakov et al. 2002. The first order includes alliance Pino sibiricae–Laricion Ermakov et Alsynbayev 2004 and two associations – Carici globularis–Pinetum sibiricae ass. nov. and Linnaeo–Pinetum sibiricae ass. nov. occurring on long-term frozen soils with different moisture regimes. The second order of the East Siberian-Mongolian type is represented by community Senecio nemorensis – Larix sibirica(Rhododendro–Laricion Ermakov in Krestov et al. 2009). The third order of boreal forests – Piceo obovatae–Pinetalia sibiricae Ermakov 2013 represents extra-zonal communities of the Ural-Siberian geographical type occurring in the moderately warm habitats. Hemiboreal light-coniferous forests of the East Siberian-Mongolian type (class Rhytidio–Laricetea Korotkov et Ermakov 1999, alliance Festuco–Laricion Korotkov et Ermakov ex Ermakov et al. 2000, Campanulo turczaninovii–Laricetum sibiricae ass. nov.) are locally found in the driest sites. The results of the classification and comparative plant-geographical analysis make it possible to correct the border between the East Siberian and Euro-Siberian geobotanical subregions as well as the boundaries of districts, provinces and regions in the forest zonation system of Southern Siberia.
采用Brawn-Blanquet方法和聚类分析对Bolshoy-Agul河流域（萨扬东部）的森林进行了分类。揭示了北亚的两个地带性森林类别——Br.-Bl.等人1939年的Vaccinio–Piceetea Br.-Bl的北方森林和Rhytidio–Laricetea Korotkov等人1999年的半北方森林。北方针叶林主要由东西伯利亚蒙古型的两个目代表——Ledo–Laricetalia Ermakov et Alsynbayev 2004和Lathyro–Laricetalia Ermakov et al.2002。第一个目包括2004年西伯利亚皮诺-Laricion Ermakov和Alsynbayev联盟和两个协会-球果-西伯利亚松和林奈-西伯利亚松。东西伯利亚蒙古型的第二目以千里光-西伯利亚落叶松群落为代表（Krestov等人2009年的Rhododendro–Laricion Ermakov）。北方森林的第三级——Piceo obovatae——Pinetalia sibiricae Ermakov 2013代表了乌拉尔-西伯利亚地理类型的温带群落，分布在中等温暖的栖息地。东西伯利亚蒙古类型的半北方轻型针叶林（Rhytidio–Laricetea Korotkov et Ermakov 1999，联盟Festuco–Laricion Korotkovet Ermakov ex Ermakovet al.2000，Campanulo turczaninovii–Laricetum sibiricae ass.nov.）在最干旱的地区局部发现。分类和比较植物地理分析的结果使纠正东西伯利亚和欧洲西伯利亚地植物亚区之间的边界以及南西伯利亚森林区划系统中的区、省和地区边界成为可能。

Modes of reproduction vary considerably in the genus Taraxacum. In particular, the extent and distribution of sexuality are decisive criteria for the evaluation of variation and the taxonomic conclusions in this complicated genus. Taraxacum sect. Borealia is widespread in the Arctic and Subarctic regions of the Asiatic part of Russia, but sexual reproduction has not been known to occur there, unlike T. sect. Arctica with a number of sexually reproducing species in the continental Far East. A detailed analysis of the herbarium material of Taraxacum kolymense Khokhryakov, using pollen size analysis and achene set examination, revealed sexuality in this distinctive member of T. sect. Borealia. The lectotype is selected for T. kolymensefrom a rich type gathering consisting of seven herbarium specimens, and a new consolidated description was compiled.

We present the study of the structure of the seed coat of 52 species from 31 genera (Acmella, Ambrosia, Aspilia, Balsamorhiza, Blainvillea, Borrichia, Chrysogonum, Clibadium, Delilia, Echinacea, Eclipta, Engelmannia, Helianthella, Helianthus, Heliomeris, Heliopsis, Iva, Lindheimera, Parthenium, Ratibida, Rudbeckia, Sanvitalia, Silphium, Sphagneticola, Synedrella, Synedrellopsis, Tithonia, Verbesina, Xanthium, Zaluzania, Zinnia) of ten subtribes of the tribe Heliantheae of the Asteraceae family. The study of the seed coat structure was carried out by scanning electron microscopy. It has been established that the species of the tribe have a distinctly sculptured or smooth, well-developed testa, which remains until the full maturity of the achenes. The sculpture of the seed surface in most species is determined by the exotesta cells. The several types and subtypes of the structure of exotesta cells due to the degree and type thickening of cell walls were revealed. The sculpture of the surface of the seeds of the species that make up the tribe is diverse. The shape and specifications of the thickening of the walls of the exotesta cells within the genus and subtribe are diverse, as a result, it is not possible to identify the characters inherent in the entire Heliantheae tribe, as well as its subtribes and genera. The division of the Heliantheae tribe into subtribes is not supported by the results of our study. The conservative nature of the characters of the testa cells structure allows to use them in solving problems of taxonomy of genera, phylogenetics, to establish the degree of homogeneity of taxa united in genera and subtribes of the Heliantheae tribe.

Conservation of biological diversity is one of the most important issues in conservation biology, so a wide range of quantitative spatial methods have been used to determine the biodiversity hotspots and the conservation priority areas. The main aims of the present study are determining the areas of endemism as well as the centers of diversity of the genus Onosma based on the GIE, IPAs, species richness, and AZE-like criteria approaches, to assess the status and priorities of conservation of the mentioned genus in Iran. Based on the findings of this research, centers of species richness, the main areas of endemism, top-ranked IPAs, and AZE-like criteria are situated in the Zagros ecosystems. The comparison of the four approaches used in this study shows that the IPAs and GIE techniques have succeeded in identifying the most important centers of diversity and endemism of Onosma in Iran. Considering that this genus with a high percentage of endemic species is one of the most important genera of Iranian flora and only 46 % of the IPAs and areas of endemism specified in the research are located in protected areas, identification and protection of the rest of these areas is one of the prevalent measures needed for conservation of Onosma species diversity in Iran.

During floristic research in 2017–2022 in the Emirate of Fujairah in the United Arab Emirates (UAE), the authors discovered new alien species that complement the species composition of the flora of vascular plants in the Emirate and the UAE as a whole. The article presents new records of five alien species previously unknown from the flora of UAE and Fujairah: Gomphrena serrata L. (Amaranthaceae), Portulaca pilosa L., P. grandiflora Hook., P. umbraticolaKunth (Portulacaceae), and Peperomia pellucida (L.) Kunth (Piperaceae). Gomphrena serrata which is rare in the country was found only in one place in the mountainous region of Fujarah, and it is a novelty for the flora of the Arabian Peninsula as a whole, while Portulaca pilosa was observed in several different areas of Fujairah Emirate and is also known for Saudi Arabia, Yemen and Oman. Peperomia pellucida was found only in a single locality in the “Alamarey plant nursery” in Dibba town but in large number of individuals. For every species, synonyms, overall distribution, habitat preferences, affinity and taxonomic remarks as well as the list of localities are given. The herbarium materials were deposited in the Herbarium of the Komarov Botanical Institute (LE, Saint-Petersburg, Russia), duplicates were sent to the Herbarium of Altai State University (ALTB, Barnaul, Russia) and the Scientific Herbarium of Fujairah (FSH, Wadi Wuraya National Park, Fujairah, UAE).

Gomphrena serrata which is rare in the country was found only in one place in the mountainous region of Fujarah, and it is a novelty for the flora of the Arabian Peninsula as a whole, while Portulaca pilosa was observed in several different areas of Fujairah Emirate and is also known for Saudi Arabia, Yemen and Oman. Peperomia pellucida was found only in a single locality in the “Alamarey plant nursery” in Dibba town but in large number of individuals. For every species, synonyms, overall distribution, habitat preferences, affinity and taxonomic remarks as well as the list of localities are given. The herbarium materials were deposited in the Herbarium of the Komarov Botanical Institute (LE, Saint-Petersburg, Russia), duplicates were sent to the Herbarium of Altai State University (ALTB, Barnaul, Russia) and the Scientific Herbarium of Fujairah (FSH, Wadi Wuraya National Park, Fujairah, UAE).","PeriodicalId":45595,"journal":{"name":"Turczaninowia","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41552199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The article reports on the floral records of seven plant taxa for the Mangystau region: Cakile maritima (subsp. euxina), Epilobium hirsutum, Rosa canina, Hordeum murinum. Among the finds, Cakile maritima subsp. euxina is a new genus and species for the flora of Kazakhstan, presumably it also grows on the northern shore of the Caspian Sea, in the Atyrau (Kazakhstan) and Astrakhan Regions (Russia). Epilobium hirsutum and Rosa canina are given for the first time for the Mangyshlak floristic district, and Hordeum murinum – for the Northern Ust-Urt.
