Detection and identification of morphological and anatomical features (external and microscopic) of crushed medicinal-plant raw materials (MPR) included in a herbal mix is an integral part of the procedures ensuring the standardization and proper quality control of the finished pharmaceutical product.

The objective of the study is to examine the morphological and anatomical diagnostic features of crushed medicinal-plant raw materials included in the composition of a new anti-inflammatory mix. The study used macroscopic and microscopic methods of analysis based on the requirements set in the applicable general pharmacopoeial articles of the State Pharmacopoeia (SP) of the Russian Federation, Fifth Edition.A macroscopic analysis made it possible to identify and describe the external features of the compiled mix, as well as its isolated crushed components, corresponding to the description given in the regulatory documentation for sweet clover grass and licorice root, as well as reflected in literary sources concerning Canadian goldenrod grass and common horse chestnut leaves.

A microscopic study of the components of the mix revealed characteristic anatomical and diagnostic features of the declared medicinal raw material: features of the cuticle, structure of epidermal cells, types of stomatal apparatus, composition of trichomes, inclusions of various nature for the leaves of sweet clover, Canadian goldenrod and common horse chestnut; features of the epidermalcell structure of sepals or involucral leaflets, types of their stomatal apparatus, trichomes, inclusions, epidermal cells of petals and their inclusions, structure of pollen grains for flowers of sweet clover and Canadian goldenrod; features of parenchyma and starch grains, crystalline inclusions of fibers and wooded particles of licorice root.

The identified features will form the basis of the relevant sections of the regulatory documentation for the developed medicinal anti-inflammatory mix and will be used to control its quality, in particular, to confirm its authenticity.

This report presents the results of a study of Dagestan rare maple species (Acer L.) in nature and during introduction. Dagestan is considered as one of the centers of maple species diversity in the Caucasus. An overview of the distribution of maples in the Eastern Caucasus is given. A model of the formation of species diversity is described by crossing floral regions and provinces, including the ancient Mediterranean habitats: Hyrcanus (A. hyrcanum) and Colchis (A. trautvetteri).

It has been shown that the valley of the Sulak River, at the intersection of four mountain ranges in Foothill Dagestan, where five species of maple grow, serves as a conditional boundary between the Girkanian and Colchian elements of woody vegetation in Dagestan. As a result of this study, it has been revealed that the diversity of maple species in Dagestan is due to the complex climatic and geographical conditions. These conditions have contributed to the formation of ecosystems where there is a high degree of adaptation and differentiation of rare maple species.

In the course of the work, experimental studies were carried out to study rooting on clonal pear rootstocks: PG 12 (k), PG 17-16, PG 2, PG 333, OHF 333, Piro II, Kavkazskaya, K-1, K-2, 4-26, 4-39; on quince BA 29 (k), Northern, Provencal, Penza, No. 13, No. 25, No. 31, No. 40.

As a substance stimulating the processes of root formation, an aqueous solution was used: zircon (1.0 ml. /10 liters of water for 16 hours). Water was used as a control. The study of the rooting of green cuttings was carried out in a greenhouse with a film cover, equipped with a fogging unit.As a result of the research, it was found that green pear cuttings PG 12 (k), PG 17-16, PG 2, PG 333 had the highest rooting ability when treated with zircon and without the use of a plant growth regulator.

Clonal pear rootstocks PG 12 (k), PG 17-16, PG 2, PG 333 and quince forms BA 29 (k), Northern, Provencal, Penza were characterized by the highest growth height when using a zircon plant growth regulator and without using a plant growth regulator. The largest diameter of the conditional root collar when using the zircon plant growth regulator and without the treatment of the plant growth regulator was the clonal rootstocks of pear PG 12 (k), PG 17-16, PG 2, PG 333 and quince forms BA 29 (k), Northern, Provencal, Penza. Clonal pear rootstocks PG 12 (k), PG 17-16, PG 2, PG 333 were characterized by the largest number of roots with the use of zircon plant growth regulator and without the use of a plant growth regulator.

For the southern part of the Black Sea coast of Russia and the Republic of Abkhazia, new floristic finds are indicated: Anoda cristata (L.) Schltdl., Erysimum cheiranthoides L., Oxalis dillenii Jacq., Persicaria capitata (Buch.-Ham. ex D. Don) H. Gross. Information about the localities of finds, the geographical origin of species is provided, as well as detailed information about the species composition of plant communities.

A taxonomic review of species of the section Aquilae of the genus Anaptychia, including four lichen species — A. bryorum, A. isidiata, A. palmulata, A. runcinata, for the lichen flora of Russia and neighboring countries is given. The work was based on the results of studying specimens of our own collections in the Caucasus, the Southern Siberia, specimens stored in the herbaria of the Komarov Botanical Institute (LE), Institute of Botany and Ecology of the University of Tartu (TU), Botanical Museum of the University of Helsinki (H), as well as literature data. For the studied species of the Aquilae section, diagnostic characters, ecological and geographical characteristics of the species are shown; a key for identifying species and a map of distribution in Russia and adjacent regions are given

The paper presents the data of geobotanical characteristics of the phytocenosis with the participation of the protected species of the Russian Federation – Pterocarya fraxinifolia in the Samur forest. The structure of the vegetation cover in the studied area was revealed, according to the results of which the phytocenosis was classified by us as a complex variant of broad-leaved forest. The data of the assessment of the structure and condition of individuals of the Samur population of P. fraxinifolia showed its critical condition. Regeneration is exclusively vegetative – by root suckers. The condition of other species in the tree layer, except for Quercus robur subsp. pedunculiflora, is also unsatisfactory.
