The article is dedicated to the memory of famous researcher of flora of the Middle Volga Region, Doctor of Biological Sciences, Professor, Honored Scientist of the Russian Federation Sergey Vladimirovich Saksonov.
A classification of habitats is proposed, which is based on the topographic position of biotopes and the territorial units of vegetation that diagnose them (TUV). Units represent by phytocenoses (for many of them the syntaxonomic status of the association and below rank is established), ecological or ecological-genetic series and complexes. Any landscape with this approach is considered as a complex of territorially related habitats. Four categories of habitats of the first level, 15 – of the second and 38 – of the third are allocated for the Nenetsky Reserve territory. The definition of habitats of the first and second levels is based mainly on their topographic position, of the third – TUV is well diagnosed. "Zakharyin shore" cluster of nature reserve is characterized by the largest (28) diversity of biotopes of the second and third levels, and "Bolvanskiy" is smaller (20). Seven categories of habitats out of 22 in the "Islands" cluster are characteristic only of Dolgiy, Matveyev, Bolshoi and Malyi Zelentsy Islands, where carbonate rocks and rocky and pebble shores exist on the surface. It is in these biotopes that the largest number of species of rare plant objects that are included in the Red Book of the Nenets Autonomous Okrug is concentrated. For most categories of the proposed classification, their correspondence with the categories of European Union Nature Information System (EUNIS) is established. EUNIS is a pan-European integrating habitat system and, despite its shortcomings, serves as a standard ensuring the comparability of national and international classifications.
The flora of vascular plants of the Astrakhan State Biosphere Reserve was studied. In 1995–2019, 445 taxa of wild and invasive plants belonging to 71 families were identified. An annotated summary of the flora is given. New for the flora of Astrakhan Region are 5 species: Aconitum lasiostomum Rchb.ex Besser, Campanula trachelium L., Delphin-ium cuneatum Steven ex DC., Genista tinctoria L., Salvia pratensis L. which are given on the basis of the data of the herbarium of Moscow State University (MW). Nine species from the Red Data Book of Astrakhan Region and three species from the Red Data Book of the Russian Federation have been identified in the reserve.
The article contains a synopsis of the flora of Tyumen, which included 1029 species and subspecies of vascular plants. The city is located in the south of Western Siberia, in the subtaiga (57°10ʹ N and 65°32ʹ E). The flora of the city includes 892 species and subspecies of vascular plants, of which 639 are historical flora (until 1965), 771 are modern. The synopsis includes 137 species of cultivated plants (landscaping, fruit and berry, vegetable, spicy, etc.) – marked (*). 121 species and subspecies have probably disappeared from the territory of the modern city (without numbers). The modern flora includes 385 genera and 101 families. Leading by the number of species of the family Asteraceae (96 species), Poaceae (66) and Rosaceae (49), the genera Carex (23 species), Artemisia (12), Rumex (12), Potentilla (10). The native fraction of the flora consists of 528 species and subspecies. Most of the species be-long to groups with boreal (42.6%) and polyzonal (26.1%) distribution. The native flora is dominated by species with a wide range within the northern hemisphere: eurasian (48.3%), holarctic (26.1%), european-siberian (20.1%). The alien fraction includes 243 species and subspecies, 167 genera and 50 families. The most widely repre-sented families are Asteraceae (42 species), Brassicaceae (28), and Chenopodiacae (26). By origin, the majority of alien species are european (27.2%), mediterranean (20.2%), iranian-turanian (14.4%) and american (14.0%). Ac-cording to the time of introduction, 66 species are archaeophytes, 177 are kenophytes. The dominant species of ru-deral habitats are epecophytes (59.3%). Invasive species (Acer negundo, Elodea canadensis, Heracleum sosnowskii, Malus baccata) are actively spreading. There are 20 protected species in the modern flora of the city: Adenophora liliifolia, Carex obtusata, Cerasus fruticosa, Coleanthus subtilis, Corallorhiza trifida, Cypripedium guttatum, Dian-thus acicularis, Digitalis grandiflora, Epipactis atrorubens, E. palustris, Neottia nidus-avis, Neottianthe cucullata, Rubus caesius, Stipa pennata, Tilia cordata, Verbascum phoeniceum.
The results of the expedition work from 1987 to 2020 in 4 central municipal districts of the Udmurt Republic (Kras-nogorsky, Seltinsky, Syumsinsky, Yakshur-bodinsky) are given. they are almost entirely located within the Kilmez-zakamsky floristic region. The total species composition of native vascular plants includes 705 species from 331 genera and 95 families. The article presents lists of native species of four floras of municipal districts. Their taxonomic compo-sition is compared. It is established that their floras are quite similar. They have 523 common views. This indicates the identification of the main core of the natural flora of one of the four floristic regions of Udmurtia. The richest in the number of native plant species is the territory of Yakshur-Bodya district. It has a greater variety of ecotopes due to the greater dissection of the terrain compared to other areas compared. On its territory, several non-moral relics are pre-served, such as Polystichum braunii, Bromopsis benekenii, Galeobdolon luteum and representatives of the Siberian and Ural flora – Paeonia anomala, Knautia tatarica.
In 2015, Ophioglossum vulgatum L. (Ophioglossaceae) was included in the Red Data Book of the Vologda Region, with a 3/LC status, due to the emerging negative trend of decrease of localities and populations numbers. In the region, from 1826 to 2020, this species was reported in 90 localities in 22 (out of 26) administrative districts. Localities of ad-der's-tongue fall within the boundaries of 38 squares of grid mapping adopted by Atlas Florae Europaeae (46,9% of their total number in the region), while in 14 of them, the species was not found in the last two decades, and within certain squares, disappeared or sharply reduced its abundance in communities in several localities. Ophioglossum vulgatum usually prefers meadow and edge-meadow biotopes, but some cases of its occurrence in disturbed natural and modified habitats have been recorded as well. In communities, mosses and vascular plants (over 200 species recorded) adjoin adder’s-tongue. The most constancy show 37 species of herbaceous and 8 species of woody plants, but not one of them shows 100% constancy to O. vulgatum. The decrease in the agricultural load on meadow biotopes and the subsequent natural transformation of communities are the main threats to the existence of O. vulgatum in the taiga zone. Adder’s-tongue was recorded on the territory of eight protected areas. Necessary protection measures include (1) organization of regional "meadow" protected areas ("zakazniks" or natural monuments) in places where the largest O. vulgatum populations are found, the protection regime of which implies moderate agricultural loads in the form of cattle grazing and haying, as well as (2) monitoring of known populations dynamics and search for new adder’s-tongue populations. We assume that the emerging negative trends in the existence of O. vulgatum in the region will continue.
The findings of previously unknown coenopopulations of Camphorosma songorica and Pholiurus pannonicus in 2020 in Tambov Region and the Saratov right bank allow us to clarify the northern boundaries of their distribution not only in the Khoper river basin, but also in the middle zone of the European part of Russia as a whole.
The use of modern information technologies and intellectual Internet resources has become a powerful tool in maintaining the Red Data Book of Tula Oblast. In 2019–2020, thanks to the international Citizen Science project iNaturalist, as well as the Flora of Russia and Tula Oblast Flora portals created on its platform, a team of biologists and amateur naturalists managed to conduct more than 30 thousand photographic observations of plants in nature. Of these, 403 observations reflect the locations of 74 species included in the Red Data Book of Tula Oblast. Finds of 23 species were made in locations not previously registered by specialists. The article presents a list of species with the number of observations, as well as information about new locations.
Here we reported new records in the Syktyvkar city of rare moss Neckera pennata Hedw. included in the Red Book of the Komi Republic. The local population of this moss was studied for the first time. Population studies of Bryophyta have never been conducted before in the Komi Republic. In the territory of the recreational zone «Dynamo», we found 92 habitats of Neckera pennata, and six habitats were found in the bordering forest array (bordering site). For each location, we cited data from the herbarium label added with the information about each moss carpet (height above ground level, tree trunk circumference, carpet projection area, exposition, the occurrence of moss-capsules). Total, we studied 219 moss carpets (199 within the ski base, and 20 in the bordering area). The area of moss carpets at the main site ranged from 2 to 450 cm2 (mean area 56 cm2). At older bordering site, moss carpets were larger, from 10 to 511 cm2 (mean area 157 cm2). Total projection area of carpets at the tree trunk was 1,4 m2 (main site – 1,1 m2, bordering site – 0,3 m2). Moss dry weight was 122 g at the main site. The obtained data, after a simple recalculation per unit of area, make it possible to estimate the probable occurrence, projection area and biomass of the species in adjacent for-ests. Neckera pennata was found mainly in the spruce, mixed and aspen forests of green moss type. We did not find any relationship between the size of moss carpet and the type of forest formation. But, there is a definite relationship be-tween the age of the stand and the area of projection of the moss carpet. Moss carpets establish aspen trunks at a height ranged from 0,2 m to 2,5 m (up to 4 m at the bordering site). The carpets are mainly single. But their number on the trunk increases with the age of the stand under the favorable environment (up to 5 carpets per tree at the bordering site). The trunk circumference in the place of moss carpet establishment ranged from 52 to 197 cm (average 91 cm). Main part of the population is located in the lower and upper part of tree trunks, while the butt-end part of tree (cov-ered with snow in winter period) is less colonized. The carpet occurrence was about the same in the upper and lower part of trunk. But, the moss productivity was higher in the lower part where the largest carpets were registered. There is a tendency of a decrease in the number of carpets and their biomass with a change in exposure from strictly northern, where the maximum of these indicators is noted, towards eastern and western. The illumination of the trunks, as well as the carpet height above ground level, determines microclimate conditions, namely air moisture, which is the most important factor for this epiphytic moss. We found moss carpets not only at the living trees, but also on the dead wood, which indicates the natural dynamics of the population. Neckera pennata in most cases forms monospecies carpets, but we found several accompanying species: Campylidium sommerfeltii, Оrthotrichum speciosum, Pylaisia polyantha, Radula complanata, and Sanionia uncinata. The shape of carpets is ranged, depending on the stage of carpet develop-ment, from dot and linear through sickle and reverse-triangular to typical broadly-trapeziform, heart-shaped and broad-renal. We found an impact of air moisture and stand and tree age on the frequency of sporulation. We did not find a clear relationship between trunk diameter and the occurrence of moss-capsules. The correlation between height of carpet location and the occurrence of moss-capsules is insignificant – the share of carpets with moss-capsules de-creases with height, which might be connected with the changes in air moisture. Air moisture is also determined the higher frequency of moss-capsules occurrence on the trunks with northern exposition. The composition of stand did not affect the occurrence of moss-capsules. The population of Neckera pennata in Syktyvkar is closed to the popula-tions from the Vologda Region. The differences are due to more severe climate of the Komi Republic. Here, the moss establishes trees with less diameter, forms fewer carpets per habitat and does not from carpets high on trunks.
An object of cultural and historical heritage "Aksakovsky Park" (Orenburg Region, Russia) was allocated in order to preserve the historical sites associated with the name of the famous writer S.T. Aksakov. The pond, located in the pro-tected area, was founded in 1767–1769, has undergone several reconstructions, but has never been scientifically stud-ied. To assess its ecological state, the algae flora of the reservoir was studied. 96 species and varieties of microalgae and cyanobacteria were identified, belonging to 7 phyla, 10 classes, 24 orders, 36 families, 63 genera. Three new species for the algae flora of the Orenburg Region were found: Asterococcus superbus (Cienkowski) Scherffel, Raphidocelis dan-ubiana (Hindák) Marvan, Komárek & Comas, Cryptoglena skujae Marin & Melkonian. A. superbus is rare in Russia. Our data expands the understanding of this species distribution. Structural and functional indicators of the develop-ment of algae flora indicate both the violation of the stability of the ecosystem and the process of accelerated eutrophi-cation. In addition, the significant development of Cyanobacteria poses a potential threat to the health of animals and humans using this reservoir as a source for watering (animals, birds) or a recreation area (humans).
This article for the first time a detailed checklist of the flora of dicotyledonous plants (family Fabaceae – Lobeliaceae) of the Sverdlovsk region, based on multi-years filed research, a critical study of herbarium materials and literature sources.

Stratiotes aloides L. is a common species in European Russia. It plays an important role in the functioning of fresh, mesoeutrophic, low-flowing water bodies with silty-clay and organic bottom deposits. It was found that in European Russia S. aloides forms at least 24 associations related to 12 formations of freshwater macrophytic vegetation. At least 119 species take part in the formation of these associations. Phytocoenoses of associations Stratiotes aloides purum, Stratiotes aloides aquiherbosa, Stratiotes aloides + Lemna trisulca and Typha angustifolia – Stratiotes aloides are the most common.
Three syntaxa are validated with the previous names regarded as invalidly according to the International Code of Phytosociological Nomenclature. The validated syntaxa as follows: Astragalo albicaulis–Thymion cretacei, Centaure-tum sumensis, Hyssopetum cretacei. Brief characteristics of the syntaxa are given and diagnostic species are indicated.
The article is devoted to the description of Platanthera chorisiana, an intriguing East Asiatic and North American Orchid, which was surprisingly discovered in an isolated locality in Moscow Region, although the possibility exists that the specimen might be mislabelled. This finding is discussed in the light of the presence of some other localities of this tax-on, proved to be positioned outwards from its main distribution area, although not so distantly spaced. We provide analogies with other Orchids, especially with the recent sensational find of East Asiatic representative of genus Liparis in West Europe. In short, we discuss also some other peculiarities of Platanthera chorisiana, which put this species apart from other representatives of its genus.
As a result of expedition work in 2019 on the flora of the Oka river basin within the Nizhny Novgorod Region, a number of rare vascular plant species were identified. Their findings complement the information on the flora of this region. The article provides of locations and habitats for 36 native and 2 alien vascular plant species. Besides, additions to the flora of the biostation of the Nizhny Novgorod University are given.

Rubus hirtus Waldst. et Kit. (Rosaceae) was found in two Moscow forest parks in 2020. The nearest known locations were recently discovered in Belarus. The status of the blackberry in Moscow is unclear: whether the species is native or alien. Vectors of invasion are under discussion.
The article presents the results of studying the state of the regional population of Hemileccinum impolitum (Fr.) Šutara (=Boletus impolitus Fr.) on the territory of Belgorod Region of the Russian Federation. 3 habitats of this species have been identified in the region. It has been established that the threatening factors for H. impolitum in Belgorod Region are: the low frequency of occurrence of habitats with local populations, the point of local populations, the dis-tances between the nearest populations, the disturbance (destruction) of habitats on cause of recreational load and the collection of fruit bodies. The following set of measures to maintain this species in nature is recommended: preserva-tion of existing habitats and search for new ones in characteristic ecotopes; taking identified habitats under territorial protection; monitoring the number of known habitats at least once every 2−3 years; environmental education of the population.
The flora of vascular plants of the Troyeruchitsa State Nature Reserve and three surrounding settlements was studied. In 2016–2019, I recorded 489 species of native and alien plants on an area of 10 km2 (supplemented with 12 species from papers published earlier) were revealed, including 456 species growing within the reserve and 45 species along its borders. An annotated checklist of the flora is presented. All known locations are given for species known from 1, 2 or 3 localities. Three species (Erigeron ×huelsenii, Eupatorium purpureum, Rumex ×heterophyllus) are novelties to the flora of Tver Oblast. Six native species are new to the flora of Ostashkovsky District (Monotropa hypophegea, Plantago uliginosa, Rosa ×majorugosa, Rubus nessensis, Sparganium gramineum, Typha angustifolia) as well as 19 species of alien plants. Sixteen species from the Red Data Book of Tver Oblast and four species from the Red Data Book of the Russian Federation are reported from the reserve. A dataset of georeferenced photos uploaded on iNaturalist as part of the Troyeruchitsa Local Flora project (https://www.inaturalist.org/projects/lokalnaya-flora-troeruchitsa) encounts 434 observations of 358 species. High diversity of flora is the most important feature of the area.
The list of 51 species of vascular aquatic plants, detailed to the level of separate administrative districts or locations, the growth of 49 on the territory of the Yamal-Nenets Autonomous Okrug is confirmed by herbarium collections. In addition, hybrids, species that are known only from literature are listed, as well as those included in the flora of the re-gion by mistake.
Current actual data on the distribution of Euonymus europaeus L. in the Middle Russia are presented, with details for individual regions and areas. The materials are based on a critical study of modern literary sources, existing herbarium materials, as well as the author's own field trips. The need for new field studies in a number of areas to clarify the extreme limits of the its distribution at the north-eastern border of its range and confirmation of old collections late 19th century is noted.
In 2009–2012, Hydrocleys nymphoides , a new alien species for the flora of Russia, was noted at the treatment
facilities of Nizhny Novgorod. After the reconstruction of treatment facilities, the local population disappeared.
From the perspective of the modular concept the variability of crown architecture of virginal and young reproductive individuals of Quercus robur L. has been researched. The individuals grow in phytocenoses of the Upper and Middle Oka river. The plant communities are subdivided into three groups accordingly to their light level (% of the full light): mesophytic meadows (100%), grass birch stands and pineries with small gaps (35–55%), closed canopy pineries (15–30%). The total amount of individuals is 210. In each individual, the configuration, growth and branching of the axes of the main structural units of the crown are considered. Meanings of quantitative parameters of shoot systems were selectively measured. Four architectural types have been distinguished: "Мeadow", "Мargin", "Forest 1", "Forest 2". The individuals of the meadow and margin types grow within the 1st and 2nd light level group communities respectively. The individuals of the forest types grow within the 3rd light level group community. In a series from the meadow type to the forest types ramification of biennial shoot systems simplifies while shape and structure of the branches from the trunk and trunk itself get more complex. Thus we figured out that Q. robur has a significant polyvariance of shoot systems, which leads to formation of qualitatively different types of habitus.
The article gives a detailed checklist of the flora of dicotyledonous plants (Rosaceae family) of Sverdlovsk Region, based on the long-term field researches, critical study of herbarium materials and literature sources. Information is provided on the distribution, bioecological features and economic significance of 138 species, 1 subspecies and 4 interspecies hybrids of the dicotyledonous plants of the natural flora of the region. Species in need of protection, as well as species widely cultivated on the territory of the region, were noted. The article discusses the history of the development of environmental ideas and a network of specially protected natural territories in the region.
For the first time, a list of alien plants registered on the territory of the Middle Volga Region (within the boundaries of Samara and Ulyanovsk Regions) is published. The alien flora of the Middle Volga Region is represented by 461 species of vascular plants belonging to 275 genera and 77 families (23.1% of the total flora). For each species information is provided about the time of occurrence in the flora (archaeophyte, neophyte), mode of introduction (xenophyte, ergasiophygophyte), invasive status (ephemerophyte, colonophyte, epecophyte, agriophyte), life form, geographical element, frequency of occurrence, range of occupied habitats, as well as the date of first mention. The predominance of neophytes (394 species, 85.5%) over archaeophytes (67 species, 14.5%) was found in the alien flora of the Middle Volga region. For the first time, information is provided on the findings of such species as Cleome spinosa, Echinacea purpurea, Grindelia squarrosa, Jovibarba globifera, Phaseolus vulgaris, and Rudbeckia laciniata. All listed species are accompanied by comments. Among alien plants is dominated by epecophytes (149 species, 32.3%) and ephemerophytes (148 species, 32.1%), 142 species are colonophytes (30.8%) and 22 (4.8%) are agriophytes. 21 species belong to the disappeared ones, they are listed in the general list, but are not included in the analysis. Currently, there is a high rate of adventization of the regional flora – 161 species (35.0% of their total number) recorded in the last 20 years. According to the modes of introduction, alien species are distributed almost equally – 227 xenophytes (49.2%) and 234 ergasiophygophytes (50.8%). The most common alien species in the region have been identified. The results of distribution of alien species are presented by habitat types.
It is reported that Euphorbia davidii Subils – a new species noted in the flora of the Central Black Soil Region was found in the Belgorod Oblast (Russia). The total area occupied by the population of this species was more than 300 m2. The data on the main diagnostic differences between close species E. davidii and E. dentata Michx. are indicated and information on the findings of this alien plant in Europe and in Russia. Most populations of E. davidii have a small number of plants, but in some cases, groups of plants can occupy large area. The species noted mainly on railways and agricultural lands without introduce into natural habitats.
As a result of botanical research in 2019 were found 620 species of vascular plants in the Bekovo and Tamala Districts of the Penza Region, including 5 species of the Red Book of the Russian Federation (2008) – Fritillaria ruthenica Wikstr., Iris aphylla L., Stipa dasyphylla (Lindem.) Czern. ex Trautv., S. pennata L. s.str., S. zalesskyi Wilensky ex Grossh. and 32 species of the Red Book of Penza Region (2013). The results of the floristic survey of 11 geographical points are presented.
A. cristophii Trautv. [A. albopilosum C.H. Wright, A. bodeanum Regel, A. walteri Regel] is a type of subsection Cristophiana. It is an extremely polymorphic taxon. The species has a fairly high seed productivity, which varies widely. The seed productivity of two samples was studied, one of which, under the name A. albopilosum S. N. Wright, was introduced from the Netherlands, and the second A. cristophii was obtained from the Botanical Garden of the Institute of Biology of the Komi Scientific Center, Ural Branch of the Russian Academy of Sciences. The age of the mother bulbs – 6–7 years. In Moscow Region A. albopilosum and A. cristophii fruit sticking was 89.2 and 88.5%, the real seed productivity was 4.54 and 2.72 g per inflorescence, the weight of 1000 seeds was 5.69 and 5.20 g, respectively (average values). In A. albopilosum, an average insemination was found – 5.54 units / fruit, with up to 13 seeds per fruit being noted in the lower tier, 15 in average, and 11 seeds per fruit in the upper tier. A. cristophii recorded an average insemina-tion of 4.93 pieces / fruit, while in the lower tier there was a formation of up to 11 seeds per fruit, average – 10, top – 8 seeds per fruit.
