bank of the river. However, these plants were only identified by A.A. Khapugin in 2018. Near this site, in 1917-2008, when the sheep skin-fur factory was working, raw materials for which could have served as a source of the B. frondosa invasion (through seeds). At this location, the bank of the Tura River served as a berth for ships engaged in both river navigation and cargo tran spor ta tion. Therefore, we assume that this particular B. frondosa po pu lation could be the first one appeared in Siberia. The stu died population covers a length of 500 m, where B. frondosa is re pre sented in high abundance. In August 2019, the con struc tion of the embankment began on this site. As a re sult, the coastal Salix thickets were cut down, and the area was covered in concrete. That is why, only small part of the original B. frondosa population remained covering the area of 100 m 2 at the border of the con struction. Besides this, three solitary B. frondosa plants were found in 2020 2 km northward, upstream of the Tura Ri ver. We assume that B. fron dosa spread to this site by amateur fishermen because they grew at some dis tance from each other. B. frondosa is a new alien species to the flora of the Tyumen Re gion and a rare record in the whole of Siberia. This is the first re port of the B. frondosa's presence in the Tyumen Re gi on, based on reliable herbarium specimens, which have ci ta tions of herbarium specimen labels of this alien species, and the complete history of B. frondosa observations in the Tyu men Region is present. Photos were uploaded to the site iNaturalist.org. Taxonomic notes. B. frondosa co-occurs with B. tri par tita L. and B. radiata Thuill. The invasive plant reliably differs from the two other species by having leaves with petioles, a large ha bi tus and the ability to grow until the snow cover is establish, while both other species are die back by this time.

I.V. Kuzmin s.n. (Ueda 2021j) (Reichenbach 1832). It is also known in Ukraine (POWO 2019). Moreover, there are scans of herbarium specimens of D. × courtoisii available, which were collected in Germany (Turpel & Walisch 2021), France (MNHN, Chagnoux 2021a), Switzerland (Orrell, In for matics Office 2021), and Finland (Kurtto 2021). In Rus sia, it was discovered for the first time in the territory of the modern Kos tro ma Region by Kossinsky in 1912(Kos sin skyi 1913. However, the taxon has not been mentioned in the main floristic summary reports for Russia (including con tem porary ones) (Krylov 1931a, Shishkin 1936, Baikov 1993, Kuz mina 2004. Czerepanov (1995) just mentioned "D. × courtoisii Reichenb. (D. barbatus L. × D. superbus L.)" without pro viding any comments. Perhaps, this is due to an extreme rarity of these findings in the 20th century: there are only four herbarium specimens known which were collected in [1912][1913][1914][1915][1916][1917][1918][1919][1920] in the Kostroma and Tver Regions . However, since the beginning of the 21st century, the number of findings has increased and the species has been recorded in the Yaroslavl Region and, for the first time in Si beria, in the Tomsk Region ). There are also pho to graphs available on Plantarium website received from the Perm Territory (Pavlov 2018) and the Kemerovo Region (Nosi kov 2014). For Eastern Siberia, this species has been recor ded for the first time. It is believed that the reason of a sudden appearance of D. × cour toisii in many places on the territory of Russia at the turn of the 20th and 21st centuries is related to a huge in crease in the number of garden plots outside of populated areas which appeared in [1980][1981][1982][1983][1984][1985][1986][1987][1988][1989][1990] in little disturbed natural commu nities. Starting from this period, there've been conditions created for hyb ri di zation between the popular garden plant D. barbatus and the local species D. superbus in the forest zone of European Rus sia and Siberia . Taxonomical notes. An allozyme analysis proved the hybrid origin of D. × courtoisii . It also showed that the plants of D. × courtoisii collected in Western Siberia in the vicinity of Tomsk are a group of a first-generation hybrids (F1) D. superbus × D. barbatus. However, in the opinion of the authors of the above mentioned publication, establishing equi va lence between Russian hybrids and D. × courtoisii requires additional research, since Reichenbach (1832, p. 806) while de scribing D. × cour toisii indicates some features that do not quite correspond to the appearance of Russian hybrids: "bracts exceed a half of the length of calyx ... inflorescence is thick, corymbose-paniculate ... [when in] D. barbatus it is looser ... [when in] D. superbus, petals are like those of D. bar ba tus ..." (i. e., the plant looks more like D. bar ba tus than D. su per bus). The Tomsk's plants have petals whose shape, size, and dissection peculiarities which make them appear clo ser to D. superbus, their bracts equal approximatively one third of a calyx; their inflorescence consists of 2-8 flowers and is more or less thick, with flowers in congestion by 2-3, sometimes detached. (i. e., that the plants from Russia diverge from D. superbus). Such differences, according to the authors of the publication, may be associated with a generally high po ly morphism of the hybrids, but also with the fact that the pair of parental species in Belgium (locus classicus D. × courtoisii) was genetically more or less different from the pair of D. barbatus and D. superbus in Russia . As for the Ir kutsk plants, the ratio of calyx and bracts varies in a wide range, but the inflorescence is few-flowered. D. × courtoisii resembles most to D. fischeri and differs from the latter, first of all, in its long-creeping rhizomes and having a dee per cut of its petals . D. fischeri has largetoothed along the edges of the petals, when in D. × courtoisii they are in cised into lanceolate lobules. In addition, in D. × courtoisii, the bracts are sharply narrowed and form a long styloid tip, while in D. fi sche ri, they are gradually narrowed to form a lanceolate end. Also, the capsules of D. × courtoisii are puny, often empty, because the seeds usually do not develop, while D. fischeri has capsules with plenty of seeds. D. × courtoisii differs from D. barbatus in having quite a loose in flo res cence with flowers on more developed pedicels and petals in cised into lanceolate lobules along the edges. D. superbus differs from all the above-mentioned species in having threadlike or linear lobes, into which petals are dis sected up to a half or more of the length of the limb. Examined specimens (new record).

Diarthron linifolium Turcz. (Thymelaeaceae)
Contributor: Natalia S. Gamova Distribution and habitat. This species (described from Nor thern Mongolia) is distributed in the southern part of Eastern Si be ria and Russian Far East and East Asia (Mongolia, Chi na, Japan). However, it was not found in Republic of Burya tiya. D. linifolium prefers sandy and rocky places within the steppe and forest-steppe regions. D. linifolium is a new species and genus to the Republic of Buryatia. Taxonomis notes. D. linifolium is an annual herb. It was descri bed as the first species in genus Diarthron. Since then se ve ral species have been added to this genus, though recent re searches consider them to belong to Stelleropsis and Dendrostellera (Ga licia-Herbada 2006). No other related species are dis tribu ted in nearby regions of Eastern Si be ria.  (Rouy 1913). It is distributed in the forest zone of North-Western (Fennoscandia), Central and Eastern Europe, Wes tern Si be ria and Eastern part North America (Ivanenko & Tzve lev 2004). Previously, this taxon was not noted in the Re public of Mordovia. It inhabits thinned pine (Pinus sylvestris L.) forests on sandy soils. Taxonomic notes. D. zeilleri is a hybridogenic species derived from hybridization of D. complanatum (L.) Holub and D. trista chyum (Pursh) Holub (Tzvelev 2000, Ivanenko & Tzve lev 2004. Its rhizome-like plagiotropic shoots are predominantly the under ground type. However, they often emerge partially to the ground surface and where they are green. The underground part of the or tho tropic shoot is vertical, pale-yellow, usually 3-12 cm long, with spatulate phylloids and filmy along the edges. La te ral branches of the orthotropic shoots are noticeably flat tened, 1.5-2.5 mm wide. The branch systems can be from loosely grouped forming inverse-conical bundles to fan-sha pely prostrated. The free plates of lateral phylloids are from sickle-curved toward the branch axis to narrow-tri an gu lar. The descending bases of the ventral phylloids are less pro nounced than those of the dorsal phylloids. The base length of the free plates of the ventral phylloids is about 1/4 of the branch width, taking into account the free parts of the la te ral phylloids. The peduncles with strobili are formed on both lateral fertile branches and main axis of the orthotropic shoot. Strobili are arranged on the 2-6 long peduncles. Examined specimens (new records). RUSSIA: Mor dovian ASSR, Bolshie Berezniki District, 7 km south of the Sim kino village, pine forest on the old dunes, [54°11'10.87''N 46°08'37.72''E], 22.06.1980, coll Ame rica (Ca nada and the northern part of the USA) (GBIF Se cre ta riat 2019b). The species is much less common in Si beria, especially in the south (Krylov 1931b, Yuzepchuk 1939, Pesh ko va 1994, Baikov 2012. Some findings were made in the Far East of Rus sia (Sakhalin and Kunashir Islands), in North Ko rea and Japan (GBIF Secretariat 2019b). Everywhere the spe cies is confined to peat bogs (mainly sphagnum bogs). Since D. × obovata is a hybridogenous species, it is more of ten found in areas where habitats of both parental species D. angli ca Huds. and D. rotundifolia L occur. The latter is also ob ser ved in the localities cited by us, where the species was first found for the Republic of Altai (Khmeleva 2012) and the Al tai Mountains as a whole (Krylov 1931b, Yuzepchuk 1939, Pesh ko va 1994, Baikov 2012, Ebel 2012. While D. rotundifolia prefers moss ridges and tussocks, D. anglica is common in hollows and can be partially immersed in water. D. × obovata occupies transitional locations. Taxonomic notes. D. × obovata is differed from D. anglica by having shorter and wider (obovate) leaves that rapidly ta pering to the petiole as well as by having underdeveloped seed cap sule with often sterile seeds. D. anglica has longer leaves which have linear-wedge-shaped blade that gradually turns into a pe tiole, and the seed capsule is well developed. In contrast to D. rotundifolia with recumbent leaves, while D. ang li ca and D. × obo va ta have upright (erect) leaves (Krylov 1931b, Yuzepchuk 1939, Peshkova 1994 Distribution and habitat. E. exaltatus was described from spe ci mens grown in the Göttingen botanical garden; the place of their origin is mistakenly indicated as Siberia ("in Si bi ria") (Bobrov 1962, Tscherneva 1994. Its native range is Cent ral and Southern Europe. It is alien in the flora of Nor thern and Eastern Europe (except for the Carpathians), North America (POWO 2019). This alien species is reported here first time for the flora of the Samara Region and the Middle Volga Region. Taxonomic notes. E. exaltatus belongs to the section Ter ma Endl. The stems are 50-150 cm long, furrow-ribbed, loose at the bottom, densely whitish-tomentose at the top; leaves are 20-30 mm long, up to 15 cm wide, pinnately parted, sparsely and short-bristly above, abaxial surface is white tomentose, sometimes grayish, without glands, stem leaves are amplexicaul, with well-defined auricles; 16-18 anthodium leaves are arranged in 3-4 rows, without glandular pubescence on the back, the inner leaves in the lower part are slightly fused with each other; tuft is cup-shaped, split on top; head shaped common inflorescences are 4-6 cm in diameter.  (Razifard et al. 2016). The species is very rare in Western Siberia. It is known from the Kemerovo Region (the middle flow of the Tom' River) (Vlasova 1996, Grebenyuk 2012, the Altai Republic (Nor thern Altai) (Krasnoborov 2012), the Khanty-Mansi Autonomous Area -Yugra (Malaya Sosva Nature Reserve and the flood plain of the Ob' River in the vicinity of the Polnovat village) (Vasina 2012, Glazunov & Nikolaenko 2018. We re cor ded this species for the first time for the territory of the Tyumen Region. E. triandra grows in stagnant and slowly flowing water bodies to a depth of 1-1.5 m with a predominantly sandy bottom, on wet coastal sands, on silty and sandy alluvium (Grebenyuk 2012). In the cited locality, the water in the waterbody was trans parent to the bottom. The bottom of the reservoir is san dy with a small amount of silt. E. triandra grew in the Callitriche her ma phro ditica L. community which included a small population of Potamogeton trichoides Cham. et Schlecht. The projective cover of E. triandra did not exceed 1-2%. Taxonomic notes. E. triandra belongs to the section Crypta (Nutt.) Seub. These are small herbaceous annuals submerged in water. E. triandra has prostrate stems 2-18 cm long, usually bran ched, rooting at the nodes. Leaves are opposite, light green to green, blades are linear, broadly linear or oblong, (3)5-10(15) mm long, 1-2(3.5) mm wide, obtuse or acute at the apex; petioles very short, 0-3 mm long. Stipules are trian gular or ovate-lanceolate, 0.7-1 mm long, margins are dentate. Flowers are solitary, axillary, sessile; sepals usually 3, petals 3, white or reddish, ovoid or elliptical, stamens 3, slyles 3. Capsules are compressed-globose, three-locular, 1.2-1.7 mm in diameter. Seeds are oblong, 10-25 per locule, 0.5 mm long, slightly curved, brown, with a cellular surface (Vlasova 1996, Razifard et al. 2016. Examined specimens (new records). RUSSIA: Tyumen Re gion, Tobolsk District, 4.5 km NE from the railway station "To bolsk", 58°18'48"N 68°22'17"E, watered sand quarry, 640 m southeast of the railway, under water, depth 0.  (Egorova 1976, Alekseev 2006, in the Orenburg (Rya bi ni na & Knyazev 2009) and Chelyabinsk (Kulikov 2010) Regions, in the south of Middle and Eastern Siberia (Bubno va 1990) and the Russian Far East (Ovchinnikova 2012). Our find is the first report of the species in Western Siberia and the most northern point of the known distribution the species in Siberia (Bubnova 1990). E. klingei grows in damp and marshy saline meadows, on the shores and shallow wa-ters of water bodies. We found plants on the swampy shore of a floodplain lake with secondary soil salinity. The salinity of water in temporary reservoirs on the shore of the lake was 0.7 ‰. In the cited locality, in addition to E. klingei, we recorded a number of halophilic species growing: Salicornia pe ren nans Willd., Spergularia salina J. et C. Presl., Tripolium pan no ni cum (Jacq.) Dobrocz., Puccinellia distans (Jacq.) Parl., P. haup tiana (V.I. Krecz.) Kitag., Suaeda sp. Taxonomic notes. E. klingei belongs to the Eleocharis section (Egorova 2001). Plants have stems 20-40 cm in height with reddish-brown leafy sheaths in the lower part. One sterile scales are developed at the base of the spikelet. It covers the base of the spikelet entirely or by 2/3. The fruits are obo vate, their surface is finely meshed. E. klingei differs from the closely related species E. uniglumis (Link) Schult. in a number of characters: a larger conical stylopodium 0.5-0.9 cm in length, a larger multiflowered spikelet 1-2.5 cm in length, light-brown covering scales 4.5-5 mm in length with a wide white membranous margin, thickened stems of 1.5-2.5 mm in dia meter. Examined specimens (new records). RUSSIA: Tyumen Region, Tobolsk District, in 1.6 km W-SW from the village Savi na, shore of Lake Erek (oxbow of the Irtysh river), near a con ser ved well of mineral water, swampy coast, 58°12'02"N 68°10'42"E, 02.07.2020; coll.

Epipactis condensata Boiss. ex D.P. Young (Orchidaceae) Contributors: Alexander V. Fateryga, Ramazan A. Murtazaliev & Petr G. Efimov
Distribution and habitat. This species is known from Greece (Samos Island), Russia, Turkey (the type locality is "Bou nar bachi. Smyrna" in İzmir Province), Cyprus, Syria, Le ba non, Georgia, and Azerbaijan (Delforge 2016, Fateryga & Fateryga 2018. The only Russian region where the re cords of E. condensata were previously documented from is the Kras nodar Territory (Fateryga & Fateryga 2018, Popovich et al. 2020, although Efimov (2020) did not mention this species among the taxa restricted in their distribution to a single region. E. condensata is confined to various types of fo rest communities. In Russia, it is known to occur in pine, oak, hornbeam, and mixed forests and shrub communities (Popo vich et al. 2020). The present report is the first publication of records of E. condensata from Dagestan. Taxonomic notes. Three species in the genus Epipactis Zinn were previously reported from Dagestan by Murtazaliev (2009): E. atrorubens (Hoffm.) Besser, E. helleborine (L.) Crantz, and E. palustris (L.) Crantz; Fateryga & Fateryga (2018) added E. persica (Soó) Hausskn. ex Nannf. E. atrorubens was ob vi ously reported by a mistake since it was absent from the Cauca sus as a whole (Fateryga & Fateryga 2018, Efimov 2020). Thus, four species of Epipactis are currently known from Dages tan: E. condensata, E. helleborine, E. palustris, and E. persica. Further records of other species in this genus (e.g., E. lepto chila (Godfery) Godfery) are still expected. Although E. condensata was not included to the recent molecular phylogenetic study of the genus Epipactis (Sramkó et al. 2019), we suppose that it is a bona fide species (terminology by Sramkó et al. 2019) due to a distinctive morphology. E. con densata can be recognized among the species in the ge nus Epipactis occurring in Russia by the leaves which are app roxi mately equal in length to the internodes, the ovaries which are pubescent as well as the rachis of the inflorescence, two separate bosses at the base of the epichile, and the viscidium which is present but inefficient (Fateryga & Fateryga 2018 kov 1961). Its distribution is not well studied, the taxon is known reliably in the South of Ukraine (Nikolaev Region) and of Donbass Territory (Donetsk Peoples Republic, Lugansk Peoples Republic) (Klokov 1961, Ostapko 2005. For the first time the species is reported for the Saratov Region and probably for Russia. It grows on steppe slopes and cretaceous outcrops. Taxonomic notes. G. affrenum is a hybridogenic taxon derived from hybridization of G. octonarium (Klokov) Pobed. s. l. and G. ruthenicum Willd. (Klokov 1961). The nothospecies is some times unreasonably combined with G. ruthenicum (Cze re pa nov 1995) or Asperula rumelica Boiss. (POWO 2019). The perennial plant has several hairy, almost erect stems 50-85 cm tall. The lower and middle stem leaves are collected in whorls of 8-10, linear-bristle with curled edges, 3-40 mm in length and 0.5-0.8 mm in width, glabrous above, shortpiloses below. Inflorescence is paniculate, multiflorous, rather dense; pedicels are 0.2-1 mm long, glabrous; the corolla is pale lemon yellow or whitish, short-cone, 1.6-1.8 mm long and 2-2.5 mm in diameter, with a tube 2-2.3 times shorter than the laminas; ovaries and fruits are densely-piloses.

Genista tinctoria L. (Fabaceae) Contributor: Alla V. Verkhozina & A.L. Ebel
Distribution and habitat. The native range of G. tinctoria covers Europe, including the European part of Russia, and Asia: Afghanistan, Azerbaijan, Iran, Kazakhstan, Lebanon-Syria, the Caucasus, Transcaucasia, Ural (Chelyabinsk and Sverdlovsk Regions) and Transurals (the Kurgan Region) (Jakov lev et al. 1996, Roskov et al. 2006, POWO 2019. The eastern border of the natural distribution of the species is in Trans urals. The species has been introduced into Argentina, Iraq, Ca nada, United States, Australia (Roskov et al. 2006, POWO 2019. There are also iNaturalist observations available reported from Siberia, namely, from Novosibirsk (Shaulo 2000, Zykova 2009, Omsk (Ueda 2021o), and Tomsk Regions (Ueda 2021p). For Eastern Siberia, the species has been recorded for the first time as an adventive species that has probably escaped from cultivation. However, the Komarov Botanical Institute RAS has a specimen received from the Ledebour's herbarium that was collected in the city of Irkutsk. Taxonomic notes. G. tinctoria belongs to the Genista section (Gibbs 1966, Pardo et al. 2004). The species is high ly variable. The synonymy shows multiple attempts to dis tinguish individual forms as separated species (Shishkin 1945, Gibbs 1966, Jakovlev et al. 1996. So, for the Siberia (the Kurgan Region), besides G. tinctoria there is also G. sibirica mentioned as a separate species, that comprises bare or slightly pubescent plants with more narrow leaves (0.3-0.8(1) cm) and broader 3.5-5 mm beans (Kurbatskiy 1994). Ac cording to the diagnosis, G. sibirica resembles G. tinctoria, but it has bare, hardly striped, non-channeled or angled culms and more narrow and barer leaves (Linné 1771). However, in the typification of Linnaean specific and varietal names in the Le gu mi nosae, P.E. Gibbs synonymised G. sibirica and G. tinctoria (Turland & Jarvis 1997 (Sultanova 1973). The species was reported in Kyrgyzstan (Sultanova 1973, Lazkov & Sultanova 2014. In "Flora of the USSR" (Fedchenko 1948), "Flora of the Kirghiz SSR" (Nikitina 1957) and "Flora of Ka zakh stan" (Baytenov 1961), these plants from the Talas Ala-Too were falsely referred to H. cephalotes, and the plant is pre sented schematically in Table 58 and Figure 2 in "Flora in Kazakhstan" (1961), so that it is difficult to refer it to this or that species (Kovalevskaya 1981). According to the information provided by S.S. Kovalevskaya (1981), the distri bution area of H. talassicum is located in the Talas Ala-Too, Susamir-tau, Kovak-tau, and Fergana ranges of the Tian Shan mountains. The herbarium specimens from the National Herbarium of Uz be kistan, Tashkent, (TASH), the Institute of Biology's Her ba rium, Bishkek, Kyrgyzstan (FRU), the Herbarium of the Komarov Botanical Institute, St. Petersburg, Russia (LE), the Herbarium of the Moscow State University (MW) were reviewed. As the result of our survey, no herbarium samples col lected at the Susamir-tau, Kovak-tau, and Fergana ranges have been found. On the contrary, the herbarium specimens collected at the Santalash ridge (Kyrgyzstan, Ala-Buka district (12.08.1961, Ubukeeva (FRU)) were present. During field researches in 2019 in the mountainous regions of the South-West Tien Shan populations of H. talassicum were found on the slopes of Pskem ridges at the altitude of 2800-3100 m in the Barkrak river, which is one of the left inflows of the Oigaing river. It is the first record for the flora in Uzbe kistan. Thus, we can conclude that the distribution area of the H. ta las sicum is at the Talas Ala-Too, Santlash and Pskem ridges. The species grow on small, sandy, rocky, and gra vel slopes in the lower, middle and upper part of the mountains. The geographical distribution of the species by favorable climatic and environmental conditions has been modeled with the MaxEnt v. 3.4.1 Software (Phillips et al. 2006, Phillips & Du dik 2008. The geographical model of favourable growth areas for H. talassicum in the current climatic conditions have been compiled. Six main bioclimatic factors (mean annual tem pe rature (BIO1); isothermality (BIO1/BIO7) * 100 (BIO3); temperature seasonality (BIO4); mean temperature in the wettest period (BIO8); pre ci pi tation in the wettest period (BIO16); precipitation at the driest period (BIO17) were used to create a potential habitat areas of the species. In the resulting model ( Fig. 1), favourable climatic conditions for species growth were set from 0 to 1 with 0 as the lowest pro bability, and 1 as the highest one. The percentage for ran do mised analysis was set to 25 and the results were cross-va li dated through 500 replications. The assessment of the re sul ting model showed that the AUC (Area Under Curve) stu dy result was 0.998, and the test result was 0.996. The two re sul ting AUC values exceed 0.9, which is consistent with the mo del's predictive capability (Scheldeman & van Zonneveld 2010). Taxonomic notes. Hedysarum L. is one of the major genera of Fabaceae Lindl. There are more than 160 species globally, most of them grow in Eurasia, Central and Southwest Asia, North Africa and North America (Liu et al. 2017a(Liu et al. , 2017b. More than half of the species of the genus Hedysarum grow in Middle Asia. Conspectus Florae Asiae Media points out 72 spe cies (Kovalevskaya 1981). According to our estimations, at least 79 species of Hedysarum are known in Middle Asia, 47 of which are endemics of the Tien Shan and Pamir Alay moun tains. 19 species of Hedysarum were recorded in the first edi tion of "Flora in Uzbekistan" (Korotkova 1955). In recent years, new findings have increased the number of records of the species up to 26 (Tojibaev et al. 2014, unpublished data). Ma ny of them are local endemics from the Tien Shan and Pamir Alay mountains. Some authors consider Hedysarum as one of the polymorphic groups in local mountain flora of Uz bekistan (Sennikov et al. 2016). One of the species that resembles to H. talassicum, is H. min ja nen se Rech. f., the main difference is in the color of the brac-teole (H. minjanense has a gray-brown bracteole). It differs from H. minjanense because of its ovateoblong blades, half-ho ri zon tal pilose or densely pilose calyx, through a smaller size of corolla (the corolla of H. minjanense reaches 16 mm long), and a sparsely pilose peduncle. H. talassicum by many characteristics is closer to H. narynense E. Nikit. than H. minjanense: bracteole is 4-8 mm long, for H. na ry nense it is 2.5-3.5 mm long, wings are about half as long or half shorter than the keel (the wings of H. narynense are more than half of the keel). The data comparison for morphological features obtained in a new record (for H. min ja nense and H. narynense) are pre sen ted. The morphological characteristics of H. ta las si cum and H. narynense are described based on the herbarium spe ci mens from the TASH and the description of each species type (Nikitina 1957, Sultanova 1973 (Fig. 2).

Isoëtes echinospora Durieu (Isoëtaceae) Contributors: Valerii A. Glazunov, Svetlana A. Nikolaenko & Stepan A. Senator
Distributiom and habitat. I. echinospora is a boreal Euro-Sibe rian species, the main part of its range is located in Central and Eastern Europe, it is found in the Middle and Southern Urals, in Western and Eastern Siberia. It is included in the Red Book of the Russian Federation as a I. setacea Durieu. About the no menclature confusion and priority in the name of the spe cies is written in W. Greuter & A. Troia (2015). Se ve ral lo ca li ties are known in Khanty-Mansi Autonomous Area -Yug ra (Glazunov & Nikolaenko 2019) and one is in the Tyu men Re gion . In 2019, it was first found in the Yamal-Nenets Autonomous Area (Popova & Donetskov 2019). Taxonomic notes. It is a perennial rooting aquatic heterospore plant 5-15 cm long. The stem is spherical, 0.5-1 cm in dia me ter. The sessile leaves are arranged spirally, often ar cuate curved, narrow, with an extended base, light green, trans lu cent in the light. At the base of fertile leaves on the inner side there are mega-and microsporangia. Megasporangia are oval, 4-5 mm long and 3-4 mm wide.
Megaspores are whitish, about 0.3 mm in diameter, with a surface covered with thin brittle spines. It is found in oligotrophic lakes with clear fresh water on a sandy, less often muddy bottom, usually at a depth of 0.3 to 1.0 m. In the Kurgan Region, this plant inhabits steppificated and alkaline meadows of ri ver valleys, in floodplain shrub thickets and along the forest edges. J. grandidentata is considered to be rare and included in to the Red Data Book of the Kurgan Region. In 2019, we studied invasion centers of alien plants in the city of Tyu men. One of them was a site where the large highway enters into Tyumen from the Kurgan Re gion (i.e. Chervishevskiy tract). A major road junction was built here. At the roadside and in the roadside ditch, we found the following co-inhabited species: Tripolium pannonicum (Jacq.) Dobrocz. (50 individuals), Plantago cornuti Gouan (two in divi duals) и J. grandidentata (one individual). These plants are characteristic for southern steppe regions with partially alka line soils, which are not typical for a natural zone, where Tyu men is situated. However, we register sometimes such steppe plant species penetrated into Tyumen area. Of the mentioned plants, the locations of the first two species (together with some other ones, like Lysimachia ma ri tima (L.) Galasso, Banfi & Soldano) have been previously found in Tyumen. However, the record of J. gran di den tata is the first and unique location in Tyumen, being found in 200 km northward of the known limit of its range. This was a solitary plant. It was very large, well de ve lo ped, 1 m in height and 1 m in diameter, with a large num ber of generative stems. In 2019, the plant was actively flo we ring and fruiting, having more than 200 inflorescences. The flowers were actively pollinating by dipterans. The mo ni to ring of this location in 2020 demonstrated the same results. Despite the active fruiting in 2019 and 2020, no one young plant was found in 500-m radius around the mother plant. This indicates unfavorable conditions of the Tyumen Region for seed reproduction of J. grandidentata. J. grandidentata is a new alien species to the flora of the Tyumen Re gion and a rare record in the whole of Siberia. Photos were uploaded to the site iNaturalist.org.

Lappula heteracantha (Ledeb.) Gürke (Boraginaceae)
Contributor: Svetlana V. Ovchinnikova Distribution and habitat. L. heteracantha was described by C.F. Le de bour from Astrakhan (Volga Region) by own collec tion and are found from the territory of Russia: Europe part, Western Siberia; Western Europe: Czechoslovakia, France, Hun gary, Romania; Eastern Europe: Podolia, Crimea; South-West Asia: Caucasus, Turkey, Iran, Afghanistan; Central Asia: Mon golia, China (Popov 1953, Hlavacek 1958, Zhu Ge-ling et al. 1995, Ovchinnikova 1997, Gubanov 1999, Ov chinnikova et al. 2004). In Middle Asia species is known only from Northern Kasakhstan and the Alai Valley of Kyr gyz stan (Goloskokov 1964, Kupriyanov & Ovchinnikova 2017, Ovchinnikova & Ganybaeva 2019. L. heteracantha grows on sandy places and rocky outcrops in steppes, semi-deserts and on mountain slopes. Revision of herbarium collections TASH showed that L. heteracantha is new species from the territory of Tajikistan. Taxonomic notes. The genus Lappula Moench comprises over 70 species of hispid small to medium-sized annual or pe ren nial herbs with distribution in the northern Hemisphere and has several representatives in Africa and Australia (Ovchinnikova 2005). L. heteracantha belongs to series Lappula of section Lappula with subulate gynobase, ovate glochidiate nutlets with 1-3 rows of spinules. Ere mocarps in cenobium of the species L. heteracantha are he te romorphic, of two types. In the upper part of the fertile twigs, 2 eremocarps have an inner row of long protruding spines that are not fused together and an outer incomplete row of short anchor spines; the other two eremocarps have a wide raised cupped wing at the edge of the disc; an in complete row of short spines is located under the wing. Spiny eremocarps without wing are characted for related spe cies L. consanguinea (Fisch. et C.A. Mey.) Gürke with homomorphic nutlets (Ovchinnikova 2005, Ovczinnikova 2009 Lavandula angustifolia Mill. = L. spica L., nom. rej. (Lamiaceae) Contributor: Victoria V. Bondareva Distribution and habitat. The native range of L. angustifolia is South-Western Europe: North-Eastern Spain, South France and Italy (POWO 2019). It is rarely cultivated as an es sen tial oil, honey and ornamental plant in the South of the Middle Volga region (Saksonov & Senator 2012, Rakov et al. 2014, Vasjukov & Saksonov 2020). This species is first listed for the flora of the Samara Region as a wild colonophyte plant (self -seeding and wintering in the open ground). Taxonomic notes. In the genus Lavandula L. about 25 species distributed in Eurasia from the Canary Islands to India (Glad kova 1978). For the territory of European Russia (Cri mea), only one species of L. angustifolia is listed as a cultivated plant. It is a subshrublet 20-100 cm high, with numerous branched shoots and linear-lanceolate leaves 2-6 cm long and 2-6 mm wide, the flowers are collected in false whorls of 6-10 at the end of the stems, forming an intermittent spike-shaped inflorescence, corolla are purple, about 1 cm long (Shishkin 1954, Gladkova 1978.

Linaria grjunerae Knjaz. (Plantaginaceae) Contributors: Petr A. Kosachev & Polina D. Gudkova
Distribution and habitat. L. grjunerae from the Middle Ural was described by Knyazev (2003). He distinguished two varieties within the species: 1. L. grjunerae var. grjunerae: the Sverd lovsk Re gion, the Tagil River, on the right bank of rock "Mount Plya sha ti ha" between the villages of Tagil and Mor shinino. 07.30.2000, M.S. Knyazev (type LE, isotype SVER); 2. L. grju ne rae var. tuberculispermae Knyaz.: the Sverdlovsk Re gion, the Iset River, on the right bank of limestone rocks between the villages of Beklenischevo and Smolino. 05.08.2000, M.S. Knya zev (type LE, isotype SVER). Additio nal ly, the author gives the information about the distribution L. grjunerae var. grjunerae in the east macroslope of the Sou thern Urals, without men tio ning a specific location. At the same time Knya zev notices that there are the herbarium spe ci mens from the eastern part of Bash kiria, which probably be longs to the described type in the LE and the Institute of Bio logy of Ufa Scientific Center Academy of Sciences (Ufa) (Knya zev 2003). This species has not been reported from Si be ria (Polozhii 2003) and the Republic of Tyva (Kras no bo rov 2007). During taxonomic revision of Siberian Linaria at the Herbarium of the Central Siberian Botanical Garden (NS) a specimen of L. grjunerae collected in the Tyva Republic was found. This collection was previously misidentified as L. acu ti loba Fisch. L. grjunerae is a mountain spe cies inha bi ting the talc-chlorite (the first location) and the lime stone (the se cond location) slopes in the zone of the southern taiga. At a new location in the Republic of Tyva the plants were col lec ted at an altitude of 1400 m on the chlorite schist rocks, which is similar to habitat on "Mountain Plyashatiha". Taxonomic notes. In Tuva, six species of Linaria section from two sub-sections grow: 1. Subsectio Linaria: L. buriatica Turcz. ex Ledeb., L. melampyroides Kuprian., L. vulgaris Mill., L. acutiloba Fisch; 2. Subsectio Laeves: L. altaica Fisch. ex Kuprian., L. debilis Kuprian. In the area of growing L. grju ne rae and adjacent areas inhabit 4 species: L. vulgaris, L. acutiloba, L. altaica, L. debilis (Krasnoborov 2007). Knyazev assumes the hybrid origin of L. grjunerae, considering parental species L. vulgaris and L. debilis. Habitus, acute lobes of sepals, leaf shape hybridogeneous species of which are si mi lar to L. vulgaris; however, another complex of features, namely, smooth seeds, blue veins on the corolla tube, densely pu bes cent calyx and narrow glaucous of leaves indicates a kin ship with L. debilis. New location is more than 2,000 km distanced from the two known ha bi tats of the species. This disjunction in the distribution of the species may also indicate that the hybridization processes took place a long time ago, probably at the beginning of the Holo cene, when L. debilis spread far north (Knyazev 2003), and to the east, followed by isolation of relict populations and their active involvement into introgression process with widespread L. vulgaris.

Platycladus orientalis (L.) Franco (≡ Thuja orientalis L., and many other homo-and heterotypic synonyms, see for example WCVP (2021)) (Cupressaceae) Contributor: Denis A. Krivenko Distribution and habitat. The natural (indigenous) range of P. orientalis is located in China and Korea. This is possibly the most widely introduced Cupressaceae conifer in Asia. In ma ny areas inside and outside natural range it has escaped from cultivation and established spontaneous populations, in clu ding of Caucasus (Imkhanitskaya 2003, Farjon 2010. P. orientalis a species of open woodland and deciduous (oak, oak-birch, and oak-pine) forests. Within its natural range it is now al most invariably found in secondary vegetation or, nea rest to its original habitat, in more or less degraded woodland and forest. As a pioneer species which is relatively longlived, it can dominate certain slopes for a long time if further disturbances remain absent (Farjon 2010). Previously, this species was not known wild in Kabardino-Bal karian Republic (Shkhagapsoev 2015, Shkhagapsoev et al. 2018 although it was indicated for neighboring Karachay-Cher kess Republic (Zernov et al. 2015) and other regions of Caucasus (Imkhanitskaya 2003). Taxonomic notes. P. orientalis is representative of a monoty pic genus, closely related to the species of Thuja L. (Th. ko ra i ensis Nakai, Th. occidentalis L., Th. plicata Donn ex D. Don, Th. stan dishii (Gordon) Carrièreand) and Microbiota decussata Kom. (Mor gan 1999, Farjon 2010). All Thuja species have strong ly aromatic foliage when crushed, winged seeds, leaves paler green or markedly white underside. The foliage of P. orientalis, when crushed, is odorless, its seeds are wingless, and both sides of its foliage sprays are indistinguishable from each other in colour and texture. Finally, the cones of the Thuja species being somewhat similar in size and shape but those of P. orientalis almost three times larger with conspicuous recurved dorsal "horns" (the bract tips) on each fleshy swollen seed scale (Morgan 1999).

Distribution and habitat. The species was described based on a single collection from the northern part of the Kyrgyz Range in the Ala-Archa River valley (Soják 2003). This area be longs to the Chui Region, Kyrgyzstan. No other localities are currently known for P. × bishkekensis. The species grows on pebble and floodplain terraces of mountain rivers and mea dow-steppe slopes of different exposure. Taxonomic notes. According to Soják (2003), P. × bish ke ken sis is a rare hybrid species that resulted from crosses between P. agrimonioides M. Bieb. and P. multifida L. In its ha bi tus, this species is similar to P. multifida and differs in leaflets sparsely pubescent beneath with visible small glands and in numerous large yellowish glands on the sepals. P. multifida has hairs and shows no glands. Examined specimens (new records).

Potentilla chalchorum Soják (Rosaceae) Contributors: Alexey A. Kechaykin, Georgy A. Lazkov & Guljamilya A. Koychubekova
Distribution and habitat. The species was described based on numerous collections from the south of Central Sibe ria, Dau ria and Northern Mongolia (Soják 1970). Later, P. chal cho rum distributed from the Krasnoyarsk Territory to the Amur Re gion in Russia (Soják 2007), from the Mongolian Altai to the northeast in Mongolia (Urgamal et al. 2014), and in the Gan su (GBIF Secretariat 2019c) and Hebei (Soják 2007) provin ces in China. The species grows in different places from wet valley meadows to steppes and woodlands (typically larch and pine), sometimes forming numerous populations. P. chalchorum can also be found around tourist sites, near settle ments, and it often occupies disturbed habitats. Taxonomic notes. In some of the studies, Soják (2004Soják ( , 2007Soják ( , 2009 sugges ted that P. chalchorum is a hybrid that re sulted from crosses between P. longifolia D.F.K. Schltdl. and P. ter ge mina Soják. The author attempted to experimentally prove the hybrid nature of this species to confirm this hypothesis. He artificially crossed the putative parental species and hyb ridized P. longifolia and P. tergemina to obtain the species si mi lar to the natural species P. chalchorum (Soják 2012). The hyb rids obtained by J. Soják were found to be identical to the species P. chalchorum from natural populations collected by him in southern Siberia and Mongolia. P. tergemina grows in Kyrgyz stan (Adylov 1976), but P. longifolia has not yet been found there. However, the latter species grows in Kazakhstan on the ridges of the Zailiyskiy Alatau, Kungey Alatau and Terskey Atatau that border Kyrgyzstan (Adylov 1976). P. chal cho rum exhibits the traits of both parents, but it is closer in appearance to P. conferta Bunge, a widespread taxon in the flora of Kyrgyzstan (Lazkov & Sultanova 2011). These spe cies differ in the following morphological characters. Leaf pe tioles of P. chalchorum are covered with 0.8-2 mm hairs, petals are dis tinct ly longer than the calyx, achenes smooth, and several small glands can be found in sepal pubescence. Leaf petioles of P. conferta are covered with 2-3.5 mm hairs, petals do not ex ceed the calyx, achenes are glandular, numerous large glands, ty pi cally yellowish, can be found on the entire plant. It should be noted that the length of the P. chalchorum stems varies depending on environmental conditions (similar to many other Potentilla species), but the morphology of its leaf blades and the pubescence of the entire plant are cons tant characters.

Potentilla doubjonneana Cambess. (Rosaceae) Contributors: Alexey A. Kechaykin, Georgy A. Lazkov & Guljamilya A. Koychubekova
Distribution and habitat. The species was described from Kash mir and, according to Soják (2007), it is widespread in Afghanistan, Pakistan, and on the Pamir-Alai and Wes tern Tien Shan Ridges. Isolated populations occur in the Cauca sus in South Ossetia, Georgia and Dagestan. This al pine pe ren nial plant prefers alpine meadows, stony and ero ded areas. It is typically found in the areas 3000-4500 m a.s.l.
Soják noted that P. doubjonneana was collected in Kyrgyzstan 14 times, but the author and other botanists never cited its spe cific localities for this region. In addition, we did not find herbarium specimens identified as P. doubjonneana and marked by J. Soják or other botanists in LE and FRU herbaria. Taxonomic notes. Among all Potentilla species growing in Cent ral Asia, P. doubjonneana is closest to P. gelida C.A. Mey., P. tephroleuca Th. Wolf, and P. turczaninowiana Stschegl. All these species belong to the section Aureae (Lehm.) Juz., and the last three species also grow in Kyrgyzstan (Lazkov & Sultanova 2011, Kechaykin et al. 2020. One of the main features that distinguish P. gelida from P. doubjonneana, P. tephroleuca, and P. tur cza ninowiana is the arrangement of basal leaves on the caudex. P. gelida has two-ranked leaf arrangement, while other species exhibit multi-ranked spiral arrangement. P. doub jon nea na differs from P. turczaninowiana in larger petals (6-9 mm long rather than 4-5.5 mm) and anthers (0.7-0.8 mm long rather than 0.3-0.5 mm). P. doubjonneana and P. tephroleuca differ from each other in leaflet pubescence. In P. tephroleuca, the leaflets (all or only in basal leaves) are covered with dense short hairs between veins. In P. doubjonneana, the leaflets are glabrous, with sporadic or sparse hairs between veins.

Potentilla tschimganica Soják (Rosaceae) Contributors: Alexey A. Kechaykin, Georgy A. Lazkov & Guljamilya A. Koychubekova
Distribution and habitat. The species was described based on collections from the slopes of the Bolshoi Chimgan Mountain (Soják 1987), no other localities are currently known. The mountain range located in the northeastern part of Uzbekistan in the Tashkent Region near the border with Kyr gyz stan belongs to the Chatkal Ridge System. A possible lo ca lity of P. tschimganica was indicated earlier for the flora of Kyr gyz stan (Kechaykin et al. 2020). This species grows among shrubs, on meadow and steppe slopes of western and sou thern exposures, sometimes along roads. The altitude limit indicated for P. tschimganica habitats varies from 1500 to 2800 m a.s.l. Taxonomic notes. According to the original source, P. tschim ga nica was considered a stabilized hybrid species that resulted from crosses between P. fedtschenkoana Siegfr. ex Th. Wolf and P. pedata Hornem. (Soják 1987). Both species are found in the flora of Kyrgyzstan (Lazkov & Sultanova 2011). We agree with I. Soják's opinion that P. fedtschenkoana and P. pedata can be parental species of P. tschimganica. Their populations of ten grow in close proximity in the Western Tien Shan. The pubes cence of P. tschimganica is intermediate between P. fed tschen ko ana and P. pedata. However, the appearance of P. tschimganica is closer to P. inclinata Vill., which grows in the central and wes tern part of Kyrgyzstan (Lazkov & Sultanova 2011, Kechay kin et al. 2020. P. tschimganica differs from this species in the presence of numerous small glands on leaf petioles, re la tively large leaflets (up to 9 cm long) with 7-9 teeth on both sides. In P. inclinata, glands are absent, and leaflets are ty pi cally 5-6-toothed and 3-5 cm long. In addition, the basal and lower stem palmately compound leaf blades of P. tschim ga nica typically have 7 leaflets (less often in combination with 5 leaflets). In P. inclinata, leaf blades typically have 5-6 leaflets (leaves with 7 leaflets are less common). Distribution and habitat. P. strictum described from garden specimens, probably, originating from the Volga Region, it is distributed in the forest-steppe and steppe zones of Central and Eastern Europe, the pre-Caucasus, southern Western Sibe ria and north-western Central Asia (Tzvelev 1989, Baikov 2012. P. strictum was not previously known for the Altai Repub lic (Lomonosova 1997, Krasnoborov 2012. It grows in steppes and steppes meadow. Taxonomic notes. P. strictum is a more or less pubescent gree nish plant with an upright single stem 20-50 cm long, at the top or below branching, leafy along the entire length, shoots at the base are covered with a cover from the sheaths of dead leaves, more or less destructive, but not split into fi la men tous fibers, with a tap root up to 2.5 cm in diameter; li near leaves 2-5 (7) mm wide; 3-10 heads on long peduncles; the flowers are yellow, the marginal ones are much longer than the pubescent anthodium; achenes are naked, sometimes with single hairs at the top, 9-14 mm long, at the base without a hollow pedicel.

Rhinanthus songaricus (Sterneck) B. Fedtsch. (Orobanchaceae) Contributor: Olga A. Kapitonova
Distribution and habitat. R. songaricus is a Ciscaucasian-Western Si be rian-Middle Asian desert-steppe species. It grows in the south of the European part of Russia (Lower Volga) (Ivani na 1981a), in the southern Urals (Plaksina 2001), in the Chelya binsk Region (Kulikov 2010), in Altai (Barnaul botanical-floris tic region) (Polozhii et al. 2003), in the northern and eas tern Ka zakh stan (Baitulin & Kotuhov 2011). We indicate this species for the first time for the territory of the Tyumen Region. This species grows in saline meadows and salt marshes, in the valleys of rivers and lakes (Ivanina 1981a). In the cited lo cali ty, R. songaricus grew in a sedge-horsetail rich fen with sparse willow and birch layer. Its abundance was low. Taxonomic notes. R. songaricus is described from Middle Asia ("Songaria"). The species belongs to the section Cleistolomus Chab. It is an herbaceous annual semi-parasitic plant. It differs from other species of the section by its numerous leaves and branches that are pressed or obliquely upwards directed. In addition, it is characterized by triangular-lanceolate, longpoin ted bracts with sharp long teeth in the lower part, which are 1.5-2 times longer than the calyx. Corolla is 17-18 mm long, yellow, with a slightly curved tube (Ivanina 1981a). Examined specimens (new records).

Rochelia bungei Trautv. (Boraginaceae)
Contributor: Svetlana V. Ovchinnikova Distribution and habitat. R. bungei was described by R.E. Traut vet ter from Kopetdag mountain, Kisil-Arvat (Turk me nistan) by collection of A.C. Becker. The species oc cu pies a vast area, its is distributed in Iran, Afghanistan, Paki stan, Kash mir, Chi na, Mon golia, in Republics of Middle Asia: Ka zakh stan, Kyr gyz stan, Taji kistan, Turkmenistan, Uz be ki stan (Pav lov & Po pov 1953, Riedl 1967, Kazmi 1971, Abdul la e va et al. 1986, Zhu Ge-ling et al. 1995, Gubanov 1996, and the spe cies is also found in the Siberia (Altai) (Ov chin ni ko va 2012), and was not found from the territory of Europe. R. bungei grows at the fine-earth, stony-gravelly slopes, outcrops of variegated rocks, among ephemeral vege ta tion, from the plains to the middle belt of mountains, less often on fixed sands in depressions and crops, at an altitude 300-2300 m a.s.l. Taxonomic notes. The genus Rochelia Rchb. comprises 22 spe cies of annual ephemeral villous or hispid herbs with a small corolla with scaly vaults, the presence of a prominent bin der on the anthers, and a bilobed stigma, with a pseudo-mo no meric di eremic coenobium, dense intergrowth of ere mo carps with gynobasis, a special stellate-hairy surface of ere mo carp. The fruits of the genus Rochelia differ from the typical coenobium in that only the adaxial carpel forms two non-falling eremes, and the fruit is separated from the mother plant, representing a diaspo ra, together with the calyx and peduncle (Smirnova 1986). R. bungei belongs to section Rochelia. Narrow and inwardly curved sepals in species from the Rochelia section serve as hooks (re placing anchor spines) with which the diaspora clings to ani mal hair or human clothing. Apparently, therefore, almost all species are weeds, actively expanding their range, which distri bute from desert of Northern Africa and the Mediterranean Re gion to the mountains of the West, Middle, Central Asia, Al tai and Himalayas (Pavlov & Popov 1953, Riedl 1967, Kazmi 1971, Abdullaeva et al. 1986, Zhu Ge-ling et al. 1995, Khatam saz 2002. From related species R. leiocarpa it is dis tin guished by stellate-hairy surface of eremocarp, just as eremo carps of species R. leiocarpa are smooth or wrinkled, shiny, with out bumps on the surface. The closely related species R. kar sen sis Popov and R. microcalycina Bornm. are endemic to Turkey have a similar surface to eremocarps (Pavlov & Popov 1953 Meusel & Jager 1992). In the European part of Russia, this species within the natural range is found only in the Northwest (Tzvelev 2000). Resettlement of the species over Russia began in the XIX century (Vinogradova et al. 2010). To date, S. viscosus has been recorded in most of Euro pean Russia, except in the very south of the territory (Ko nech naya 1994, Tzvelev 2000. In Asia the species has been re corded from Kazakhstan, where it was observed in two lo ca tions of Kokshetau Upland (Epiktetov 2020, Evdokimov 2019. The species was introduced to the Russian Far East (Bar kalov 1992) and to North America (Barkley 2006). S. vis cosus is a heliophilous plant growing in dry habitats on re la ti vely poor soils, and it does not tolerate salinization. In the secon dary area it grows mainly on railway embankments, near roads, less often near housing (Vinogradova et al. 2010). In Siberia, the location of the species has been recorded since the 1980s. The first finds in the regions were noted in Al tai (Igna tov & Ignatova 1982) and Krasnoyarsk Territories (Ste panov 1990), the Irkutsk Region and Buryatia (Zarubin et al. 1993, Ivanova & Azovsky 1998, Sutkin 2010, Chepinoga et al. 2018, Kurgan (Naumenko 2008), Tyumen (Vibe 1997), Ke me rovo (Krasnoborov et al. 2002) regions, Khakassia (Skvort sov 2005. For the Novosibirsk Re gion this species is recorded for the first time. Taxonomic notes. S. viscosus is an annual 10-40 (50) cm high. Like some others species in sect. Senecio it has corymbs with ray flowers that are short, barely longer than phyllaries, with a flat or turned outward bend. In contrary to other re pre sen ta tives of this section, S. viscosus has sticky glandular pubes cence. Achenes are fusiform, brown, with thin longitu di nal ribs. For European populations of S. viscosus, naked ache nes are indicated (Stace 1997, Hodalova et al. 2004. How ever, plants with clearly pubescent achenes are rarely found in the Euro pean part of Russia. As a hypothesis requiring evi dence, this can be explained by introgressive hybridization with local species of the sect. Senecio: S. vulgaris L. or S. sylvaticus L. (Vinogradova et al. 2010). In Europe, hyb rids with S. sylvaticus L. (S. × viscidulus Scheele) are mostly sterile (Stace 1997 (Marhold 2011) and other European countries (POWO 2019), in some places in European Russia (Tzvelev 2004) and in the Ural Mountains (Chelyabinsk Region), where it occurs on grassy dumps of gravel and also on disturbed stony slopes (Kulikov 2010). The species is also recorded as an alien plant in many states of the USA and provinces of Ca na da (Morton 2005). Recently it has been found as alien plant in two locations in Kazakhstan (Ebel et al. 2015a). S. cserei is an alien species new for the flora of Sibe ria. It grows in anthropogenic habitats on disturbed soils. Taxonomic notes. This species of the genus Silene L. is an an nu al to biennial or rare short-lived perennial monocarpic be lon ging to section Behenantha Otth or subgenus Behen (Moench) Bunge which some authors are treated as a separate ge nus Oberna Adans. This group containing 20 to 25 spe cies dis tri bu ted in temperate and partly in cold and sub tro pi cal regions of Eurasia and North Africa (Tzvelev 2004). Ac cor ding to Tzvelev (2004), area of Silene cserei Baumg. s. str. (≡ Ober na cserei (Baumg.) Ikonn.) is located only in Tran syl va nia, whereas close related species Oberna schottiana (Schur) Tzvel. (≡ Silene schottiana Schur) has more wide distribution. On the other hand, the name Silene schottiana is considered to be a synonym of Silene vulgaris (Moench) Garcke (= Oberna behen (L.) Ikonn.). The latter species is a perennial widely dis tri bu ted in Eurasia. It has prominent reticulate veins on its ra ther large calyx, and the latter inflate while fruiting. S. csereii may be easy separated from S. vulgaris by the long, racemose pri ma ry bran ches of its inflorescence, the elliptic smaller calyx con stric ted at both ends, not inflated and tightly enclosing the capsule and lacking obvious venation, and the purple filaments.  (Mayorov 2018), the Udmurt Republic (Melnikov 2011). In the Asian part of Russia S. physalifolium was found in 2016 in several habitats of the Tyumensky District of the Tyumen Re gion (Nobis et al. 2020). In 1949 it was collected in the Bo dai binsky District (Australian Tropical Herbarium 2021); in 2015 S. physalifolium was observed in the Usolsksky district of the Irkutsk Region (Ueda 2021s). In the Omsk Region S. physalifolium is determined for the first time. It was found within the modern borders of Omsk, in a beet field and along the edge of an irrigation canal. Its cover reached 5 %. The species could be found on the territory of the Agricultural Production Cooperative "Bol she vik" in the Poltavsky District of the Omsk Region, since the seeds purchased for the lawn making on the territory of St. Petersburg contained an admixture of seeds of S. physalifolium (I.V. Kuz min, personal comments). The species grows in dis tur bed areas, on railways and highways embankments, in fields and ruderal habitats (Edmonds & Chweya 1997). Taxonomic notes. The species is related to Solanum nigrum L., from which S. physalifolium differs broadly by having ovoid, dark green to purple-to brownish-green ripe berries, usually with dis tinct reticulum of veins (sclereids accompanying the vas cu lar bundles are visible through the outer layers of the peri carp), usually translucent, sometimes opaque; lower half of mature fruit covered with appressed and enlarged ca ly ces, whose sepals often reflex away from fully mature berries (Edmonds & Chweya 1997, Mayorov 2018, Knapp еt al. 2020. Plants usually prostrate with many decumbent spraw ling late rals arising from the base; moderately to densely pu bes cent with spreading glandular-headed hairs (Edmonds & Chweya 1997). Two varieties of S. physalifolium species are known as var. physalifolium with South American distribution and var. nitidibaccatum, which successfully spreads beyond the pri mary range (Edmonds 1986). Plants from the Omsk Region have dentate-crenate leaf edge, 4-8-flowered inflorescences, broad ly triangular sepals, and broadly ovoid berries, that are cor res ponding to S. physalifolium var. nitidibaccatum (Bitter) Ed monds (Henderson 1974, Nobis et al. 2020. This variety was de ter mined on the territory of Russia and European count ries (Mayorov 2018, Särkinen et al. 2018, Nobis et al. 2020 (Fu & Zhu 2001). This species was considered to grow only in the Russian Far East -Amur Region, Jewish Auto no mous Region, Khabarovsk Terriory, Primorye Territory; as well as in Northeastern China and the Korean Peninsula (Lu fe rov 1989(Lu fe rov , 1995(Lu fe rov , 2016. It grows in upland and floodplain mea dows, forest edges and along roadsides (Luferov 1995). The study of herbarium collections stored at the V.L. Ko ma rov Botanical Institute (St. Petersburg) (LE) made it possible to identify the samples of Th. ussuriense for the first time in Inner Mongolia province (China). Taxonomic notes. The samples of Th. ussuriense were iden ti fied as Th. simplex L. p. p. (Komarov 1903, Nevsky 1937, Voro shi lov 1985, Th. strictum non Ledeb., auct. (Voroshilov 1966), Th. simplex subsp. strictum (Ledeb.) Worosch. comb. invalid. (Vo ro shilov 1982). Currently, the taxonomic distinction of Th. ussuriense is confirmed by its morphological, anatomical, eco logical-geographical, phenological and biochemical fea tures (Ponomarchuk & Ulanova 1972, Luferov 1989, Gavrilenko & Novozhilova 2015. Th. ussuriense is distin gui shed from the closely related Th. simplex by the following fea tures: aerial shoots up to 150-250 (300) cm tall (in Th. simplex the height of the shoots is 40-60 (80) cm); ho ri zon tal rhizomes, up to 150 cm long (in Th. simplex the rhi zomes can be horizontal, ascending or vertical, 5-30 cm, sometimes up to 50 cm long), gray roots (in Th. simplex the roots are lemon-yellow), highly branched stems (the stems of Th. sim plex are either not branched at all or with a few branches in the upper part), broad triangular leaves, triternate or tri pin nate, deflected from the stem; the leaflets are obovate or or bi cular-reniform, matte, 2-6 cm long, 1-5 cm wide (in Th. simplex the leaves are narrowly triangular, usually biternate or bipinnate, rarely tripinnate, compact; the leaflets are lan ceo late, narrow obovate, with glossy upper side, 1.5-3, rarely up to 4 cm long, 0.5-2 cm wide); the inflorescence is a broad py ra mi dal branching panicle (the inflorescence of Th. simplex is a narrow pyramidal panicle with compressed branches), the stig ma is ovate (in Th. simplex the stigma is sagittate or triangular).

Distribution and habitat. T. austrosibiricus is endemic to moun tai nous areas of the southern part of Western and Cent ral Siberia: Tuva Republic, Kemerovo Region, Kras noyarsk Territory, Khakassia Republic. This species grows in sub alpine and forest zones, in moist valleys at 350-2600 m a.s.l. It occurs in forest glades and fringes, in mixed-grass and mixed-grass-cereal dry and swampy meadows, along the banks of rivers, streams and small ponds with fresh water (Erst et al. 2019). Taxonomic notes. T. austrosibiricus is morphologically close to T. chinensis Bunge. It is well distinguished by simple rhizomes (rather than by the multi-headed basal part of the plant, as in T. chinensis), shorter aerial shoots, smaller flowers and shorter persistent styles. T. chinensis is an East Asian spe cies occurring in Russia (Primorye and Khabarovsk Territories, Sakhalin Region), in the north and northeast of China and on the Korean peninsula (Siplivinsky 1972, Voroshilov 1982, Luferov 2004. The indication of the distribution of T. chi nen sis in western Mongolia (Uvs Province, Harhiraa), Siberia (Kras no yarsk Territory, Buryatia Republic) is based on an in cor rect identification of specimens, some of which belong to T. aust ro si biricus (Serebryanyi 2019). T. austrosibiricus is distin gui shed from T. asiaticus L. by having a smaller number of se pals, lon ger persistent styles and petals longer than sepals. T. asiaticus grows mainly in extra-tropical Asia (Western and Eastern Si be ria, Mongolia, northeast Kazakhstan and China), as well as in the northeast of European Russia (Schipczinsky 1937, Sip li vinsky 1972, Doroczewska 1974, Borodina-Grabovskaya 2001, Friesen 2003. Examined specimens (new record). RUSSIA: Altai Re pub lic, Kosh-Agachsky District, Upper Boguty Lake, 49°42'52.8"N 89°29'48.3"E, mountain steppe, 2475 m a.s.l., 08.08.2020, coll. A.S. Erst & T. Erst (NS) Typha latifolia L. (Typhaceae) Contributor: Olga A. Mochalova Distribution and habitat. T. latifolia is widespread semiaqua tic species. It is found as a native species in Eurasia, North and South America, Africa, and an introduced and in va sive species in Australia, New Zealand (GISD 2021). In Rus sia, it is found in the European part, Siberia and the Far East. In the northern part of the Russian Far East T. latifolia has been found in Central (Milkovo, Shchapino, Lazo, Esso in basin of Kam chatka River) and South Kamthatka (Paratunka) (Yaku bov & Chernyagina 2004). In Yakutia (Eastern Si be ria), broadleaf cattail has been found from Upper and Middle Lena valley (Vi lyui sky and Aldan district of Yakutia) (Krasnoborov & Ko rot kova 1988). The new locality is situated ~ 950 km south east from Kamchatka localities and 1050 km west from Yakutian localities. The new record in the Ma ga dan Region is the most northeastern in Russia and it is of an invasive character. We assumed 2 version of introduction for T. latifolia in the Ma ga dan Region: by vehicles or by people returning from va ca tions. We found out that most likely it was brought from the No vo sibirsk Region in 2004: "the broken bunch (pistillate spikes) was thrown into a roadside ditch, not on the road". In the new locality, this species is found near 200 m from the par king with roadside café not far from the highway. The site is heavily polluted by road dust. Such areas thaw in spring 1-2 weeks earlier than natural habitats, which pro bab ly determined the success of the Typha population here. T. latifolia grows in the widening of the watercourse (70 × 40 m) with thickets of willows on the shore. In 2017, broad leaf cattail grew in the 3 small thickets at a depth of up to 0.6 m. The area of the largest group of them was about 30 m 2 . In 2020, there were five sites with T. latifolia. The total pro jec tive cover of the community with broadleaf cattail was 70-80 %. The communities are dominated Equisetum fluviatile L. with Eleocharis palustris (L.) Roem. et Schult., in addition, the communities contain Calamagrostis langsdorffii (Link) Trin., Eriophorum scheuchzeri Hoppe, Carex vesicata Meinsh., Ranunculus gmelinii DC., Potamogeton berchtoldii Fieb. etc. Taxonomic notes. T. latifolia is variable separate slightly taxon may be shed partly as mixtures of differ ploid race, perhaps due to introgression hybridization. This species shares range with other related species, and hybrids. Reproduction is both by seed and ve getatively by rhizomes. T. latifolia rapidly colonizes exposed wet area, as it produces an extremely high number of wind water dispersed seeds. In the new Magadan locality, 30.06.2017 T. latifolia was represented by vegetative shoots 0.2-0.4 m height. At 8.09.2017 there were with as pistillate spikes, as staminate spikes partially showered. A week later (15.09.2017, coll. E.A. Dubinin) most pistillate spikes have al rea dy crumbled. At September erect shoots 1.0-1.3 m, 1.5-2 cm thick in base; leaf 1-1.5 cm wide. Pistillate spikes in fruit 9-15 cm, some of them were curved or underdeveloped. Some plants are in poor conditions. Due to the abundance of curved spikes and small size, we assumed it was a hybrid plants.
