Flora of the Troyeruchitsa State Reserve (Tver Oblast, Russia)
Pp. 4-31
Abstract. 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 ( encounts 434 observations of 358 species. High diversity of flora is the most important feature of the area.

Polyvariance of the habitus of virginal and young reproductive individuals of Quercus robur L. (Fagaceae) in phytocenoses of the Upper and Middle Oka river
Pp. 66-90
Abstract. From the perspective of the modular concept plasticity of crown architecture in 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. For each individual shape, growth habit and ramification of axes of the main structural units of crown. 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 habit types.

Platanthera chorisiana Cham. (Orchidaceae),
a possible new member of the flora of European Russia
Pp. 116-124
Abstract. 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 taxon, 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.

Hemileccinum impolitum (Fr.) Šutara (Boletaceae)
is a candidate for inclusion in the Red Book of Belgorod Region
Pp. 166-178
Abstract. 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 distances 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: preservation 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.

Habitats of the East European tundra and their accordance by the EUNIS categories
on the Nenetsky Reserve example
Pp. 359–397
Abstract. 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.

Flora of the Tyumen city
Pp. 420–497
Abstract. 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 belong 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 represented 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%). According to the time of introduction, 66 species are archaeophytes, 177 are kenophytes. The dominant species of ruderal 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, Dianthus acicularis, Digitalis grandiflora, Epipactis atrorubens, E. palustris, Neottia nidus-avis, Neottianthe cucullata, Rubus caesius, Stipa pennata, Tilia cordata, Verbascum phoeniceum.

Native flora of the central regions of the Udmurt Republic
Pp. 498–523
Abstract. The results of the expedition work from 1987 to 2020 in 4 central municipal districts of the Udmurt Republic (Krasnogorsky, 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 composition 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 preserved, such as Polystichum braunii, Bromopsis benekenii, Galeobdolon luteum and representatives of the Siberian and Ural flora – Paeonia anomala, Knautia tatarica.

Ophioglossum vulgatum (Polypodiopsida, Ophioglossaceae) in the Vologda Region, Russia
Pp. 524–544
Abstract. 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 adder'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.

Population of the Neckera pennata Hedw. (Bryophyta, Neckeraceae)
in the Syktyvkar city (Komi Republic)
Pp. 560–586
Abstract. 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 forests. 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 between 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 (covered 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 development, 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 decreases 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 populations 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.

Algae flora of the water reservoir of the object of cultural and historical heritage
"Aksakovsky Park" (Orenburg Region, Russia)
Pp. 587–602
Abstract. 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 protected area, was founded in 1767–1769, has undergone several reconstructions, but has never been scientifically studied. 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 danubiana (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 development of algae flora indicate both the violation of the stability of the ecosystem and the process of accelerated eutrophication. 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).
