In connection with the critical revision of species of the genus Buglossoides Moench of Eastern Europe, Asia Minor and Central (Middle) Asia, herbarium materials in collections stored in the Herbariums of LE, MW, TASH, NSK, NS, TK, as well as virtual collections posted on the aggregator Global plants on JSTOR were studied. The revision of collections and new specimens made it possible to identify changes in the taxonomy and distribution of species of the genus Buglossoides, to describe a new species for science B.asiatica Ovczinnikova from Central Asia, and to cite new localities for three species: B.tenuiflora (L. f.) I.M. Johnst. is first recorded for Tajikistan, B.rochelii (Friv.) Stoyanov, Mátis et Sennikov is first recorded for Turkmenistan, and new locations of this species have been identified in Turkey and the Lower Volga Region: in the Volgograd, Voronezh and Saratov Regions. B. sibthorpiana (Griseb.) Czerep. is first recorded for the Lower Volga Region (Astrakhan Region) and the Republic of Dagestan. The summаry includes a nomenclatural citation for all taxa, citations of type specimens and new locations, information on ecological features and distribution, and a key to identifying the species. The description of B.asiatica includes a diagnosis, a table of diagnostic features of the new species and the species to which it was included, an illustration of the main features of the eremocarps, a photograph of the holotype and a range map.

The anthecological features of the polycarpic, bulbous, semi-rosette plant, Gagea minima (L.) Ker Gawl, were studied in the Moscow Region. Observations were carried out in 2021-2024 according to generally accepted methods. The flowers are weakly protandrous. There is a gradual opening of the anthers of all six stamens over 3 days. The duration of flowering of an individual flower is 4-8 days when an overlap of the staminate and stigma stages is observed. In the evening (after 18 pm) and under unfavourable conditions, the perianth closes and the flowers droop. The synflorescence is an open thyrsus, in which the number of axes of the second order (composed monochasia) is 1-3. The opening of flowers in the synflorescence as a whole and its structural units (monochasia) occurs in a clear sequence, according to the order of branching of the shoot on which the flowers are borne. In sunny and fairly warm weather, the flowering period of synflorescences is 6-8 days, while in cloudy and cool weather it increases to 12 days. According to the ratio of pollen grains and ovules in flowers (308 ± 18), G. minima is a facultatively autogamous plant. The plants display a morning opening rhythm with a maximum at 8 am. Flowers that bloomed the previous days open earlier than flowers that open for the first time.

According to the descriptions, the Siberian species Elymus peschkovae Tzvelev and E. confusus (Roschev.) Tzvelev (Triticeae, Poaceae) differ in the presence or absence of trichomes on the surface of lemmas and the segments of the spikelet axis (rachillas). Two methods were used for studying the microevolutionary relationships between these species: hybridization of biotypes from different locations and analysis of the nucleotide sequences of the low-copy nuclear gene GBSS1. The created and grown hybrids in combinations E. peschkovae × E. confusus: AMU-8804 × BER-0807 and AMU-8804 × BUK-1109 showed complete seed sterility in two field vegetations. In the interspecific hybrid E. confusus TAR-0730 × E. peschkovae JTO-1708, a single grain was found from which an absolutely sterile individual was grown. Taking into account the vast species ranges, three hybrids were created between Magadan biotypes from the same habitat in the combination E. confusus MOL-1887 × E. peschkovae MOL-1882. The plants showed seed fertility (SF) values of no more than 1-2 grains per spike. Five grown F₂ plants of this combination showed complete sterility. At the same time, intraspecific hybrids of E. confusus between biotypes from different geographical habitats in three cross-combinations showed a relatively high SF. In addition, a comparative study of the GBSS1 gene sequences in accessions from our collections was carried out compared with clones of reference species. Differentiation of clones by the St2 subgenome in E. confusus, E. peschkovae and E. sibiricus L. did not reveal any clear relationships between the species. At the same time, species specificity in the H1 subgenome was noted, confirming the existence of microevolutionary isolation of E. peschkovae and E. confusus. It was concluded that reproductive relationships between individuals of the two species are possible according to the model of introgressive relationships between E. fibrosus (Schrenk) Tzvelev and E. caninus (L.) L.

Currently, the CSBG collection contains 27 cultivars of the genus Syringa L. The collection was replenished with 60 cultivars of the genus Syringa from 5 botanical institutions and nurseries located in other climatic zones from 2018 to 2022. New cultivars were planted in the scientific nursery of the laboratory of dendrology to study the features of biology, winter hardiness and subsequent introduction into urban greening in the continental climate of southern Western Siberia.

The preliminary results of studying the complex of anthophilous insects of introduced woody plants Syringa vulgaris L. and S. josikaea Jacq. (Oleaceae) are presented, as well as characteristics of their seasonal development. The research was carried out over three years (2019-2021) on the territory of the Dendrological Park (Novosibirsk) using standard methods. The phenological development of shrubs generally corresponded to the growing season of local species of the Novosibirsk Region. The timing and duration of flowering of woody plants was influenced by weather conditions. The life status of model plants of S. vulgaris and S. josikaea was good. Flowering of S. josikaea shrubs was estimated as good (2019 and 2021) and abundant (2020), flowering of S. vulgaris was good (2019-2021). On the inflorescences of model plant species, a total of 56 species of insects belonging to 5 orders were noted: Hymenoptera (18), Hemiptera (14 species), Coleoptera (12 species), Diptera (9 species), Neuroptera (2 species) and Lepidoptera (1 species). Of these, 17 species were classified as pollinators and 39 species as insect visitors, of which 19 were insect pests, 10 parasites, 5 predators, 4 nectophages and 1 pollinophage. Among the pollinators, 5 major and 12 minor pollinators were identified; no specialized pollinators were noted. All pollinators were polylectic species. The anthophilous insect complex of S. vulgaris differed from S. josikaea both in insect density and in the number of species. The inflorescences of S. josikaea turned out to be the most attractive to insects. The similarity in the species composition of anthophilous insects of S. vulgaris and S. josikaea was 39 %: 22 common species were noted, of which 3 species were classified as major pollinators and 2 as minor pollinators. In general, the anthophilous insect complex of S. josikaea turned out to be much more diverse than that of S. vulgaris.

Based on the results of an analysis of tree collection of the Rosaceae Juss. family of the Donetsk Botanical Garden (DBG), a list of medicinal plants, used for treatment in official and traditional medicine, was compiled. This list includes 58 species from 20 genera. The official medicinal plants include 18 species, 13 of them being pharmacopeial ones. Collection of the Rosaceae family has been formed mainly in the 1970s. Most of the species are long-lived, have been part of our collection for more than 50 years, have successfully adapted to the conditions of the region, bloom and bear fruit. The paper provides a brief description of official medicinal plants, 7 species among them belong to the natural flora of the region. For each species the history of introduction into our collection is described, the characteristics of bioecological features in the natural, climatic and environmental conditions of our region are given and the vital state is assessed. Most medicinal woody plants after successful introduction trials are widespread in green spaces of industrial cities in our region along with native species.

The paper presents the first data on the findings of agaricoid fungi in the greenhouses of the Central Siberian Botanical Garden SB RAS. A total of 15 species of agaricoid basidiomycetes (Basidiomycota, Agaricomycetes, Agaricales) from 11 genera and 6 families were found in the greenhouse complexes of the botanical garden located in the Sovetsky district of the city of Novosibirsk. Half of the species belong to the family Agaricaceae, including some of lepiotaceous fungi known from warmer areas. All the identified species are saprotrophs, growing on soil and plant residues. Most of the species from the families Agaricaceae, Hymenogastraceae, Mycenaceae, Pluteaceae, Psathyrellaceae and Strophariaceae which were discovered in the greenhouse interiors of the Novosibirsk Botanical Garden were found in the natural forests of the surrounding areas, and were brought into the greenhouses, florariums, flower pots with substrate or fertilizer (soil, woody remains, bark, moss, manure). Only five species (Cystolepiota fumosifolia, Leucoagaricus americanus, Leucocoprinus brebissonii, L. straminellus and L. cepistipes) are specifically greenhouse species and were most likely introduced into the greenhouses of the Central Siberian Botanical Garden with planting materials of tropical plants. All of the species listed above are new for the Novosibirsk region. Cystolepiota fumosifolia is new for Siberia and Russian Federation. Of the 15 identified species of agaricoid fungi, Cystolepiota fumosifolia, Leucocoprinus cepistipes and L. brebissonii were the most common. The fruiting of Cystolepiota fumosifolia and other species found in the greenhouse soil of the demonstration greenhouses ceased after the greenhouse plants were transferred to another building. In the florarium, located in the greenhouse complex of the main building of Botanical Garden the fruiting of Leucocoprinus cepistipes is recorded annually in the winter.
