The necessary basis for studying the structure and dynamics of populations is an investigation of ontomophogenetic peculiarities and establishment of ontogenetic stages of individuals. Information about ontomorphogenesis is especially important for protected species of plants. The minimal amount of data on morphology of plants in the different periods of ontogenesis complicates plant identification and evaluation of population state conditions in nature and culture. Trifolium rubens L. is a perennial Central European plant listed in the Red Book of Ukraine as a rare species. The objective of this research is to analyze the peculiarities of ontomorphogenesis of T. rubens, to establish diagnostic signs of age stages and the sequence of their passage for identification of the multivariance of development. The results of the study on T. rubens ontomorphogeny at the M. M. Gryshko National Botanical Garden оf the National Academy of Sciences of Ukraine and in the natural population in Zakarpattya are represented in this article. The terms “age stage” and “age period” are used to describe the degree of ontogenetic development of individuals. Diagnostic features of the age periods: latent, pregenerative, generative and senile are established. Detailed morphological descriptions of plants in different stages of ontogenesis are presented. The study shows a multivariate development that reveals different sequences of passing ontogenesis stages by individuals and, accordingly, the rate of their aging and life expectancy. It was found that during the first year of vegetation the plants undergo two periods (latent and pregenerative) and 5 stages of ontogeny (latent, seedlings, juvenile, immature and virginile). The first bloom in plants appears mainly in the second year of vegetation. The research showed the change of the leaf blade shape in ontogeny from simple to compound. There is a difference in the pubescence of leaf parts, and leaf shape indicates that these features are age-old. It was concluded that the aboveground part of the immature, virginile, generative individuals during the flowering period of plants differ from subsenile and senile in shape and number of leaves. In the generative period of ontogeny in dense plantings or in the natural population, it is difficult to reliably determine the boundaries of an individual by the aboveground part. The correlation between vegetative shoots of different type and generative shoots in the individual or group of plants can be used as an indicator to estimate the ontogenetic status of a particular locus or population. Successful growth of T. rubens in culture outside the natural range indicates good prospects for its ex situ protection and the implementation of measures for repatriation and restoration of populations in nature. The data of the research may be used for evaluation of the age structure of T. rubens populations.

Investigation of plant ontogenetic peculiarities and establishment of boundaries of ontogenetic states of individuals is a necessary basis for studying their populations. The minimal amount of data on morphology of plants in the pregenerative period of ontogenesis complicates plant identification in natural and cultural populations. Such information is especially important for rare species of plants. Dictamnus albus L. is a perennial rare plant listed in the Red Book of Ukraine.The objective of this research is to analyze the peculiarities of ontomorphogenesis of D. albus, to establish diagnostic signs of age stages and the sequence of their passage for identification of the multivariance of development. The results of the study on D. albus ontomorphogeny in the latent and pregenerative period at the M. M. Gryshko National Botanical Garden оf the National Academy of Sciences of Ukraine are represented in this article. Diagnostic features of age stages: seeds, seedlings, juvenile, immature, virginile are established. The study shows a multivariate development that reveals different sequences of passing ontogenesis states by individuals and, accordingly, the rate of their aging and life expectancy. To describe the variation of the passage by individuals of ontogeny stages, we divided the stages into ontomorphs, which determined the degree of development-degradation of plants. The research showed that every age stage lasts for one growing season or longer. The first bloom in plants does not come earlier than the sixth year of vegetation. Seedlings and juvenile plants vary in leaf number and phyllotaxy. The development of immature plants takes place from the third year of vegetation. Seedlings, juvenile and young immature plants have a tap-root system. In individuals older than 4 years a root system forms which becomes similar to the fibrous root system due to the presence of several thickened roots. In immature and virginile plants, we observed the formation of adventitious roots on the caudex. It has been found that D. albus is characterized by heterophylly and morphological variability of leaves, which is developed during ontogeny and shoot formation. The variety of the architecture of individuals in the early stages of ontogenesis and the multi-variation of their development indicate the variation of the reaction rate.The data may be used for evaluate age (ontogenetic) structure of D. albus populations.

Global climate change and increased land use lead to the loss of biodiversity at all levels of the organization of living organisms – ecosystems, species, landscape population, genetic, molecular biological levels, etc. The reaction of plants to anthropogenic impact, according to experts, may be even stronger than postglacial changes. A shift in the thermal isotherm will cause the plants to either move and adapt, or disappear. Endemic species that make up “biodiversity hotspots” require special attention. Cornus sessilis Torr. ex Durand, the object of our research, is part of one of these points – the California Floristic Province. Researchers are now focusing their efforts on developing a climate change – related biodiversity management strategy. In the case of the threat of extinction of the species in nature, there is a important method of preserving it in culture (ex situ). M. M. Gryshko National Botanical Garden at the National Academy of Sciences of Ukraine (the NBG) pays great attention to the introduction of rare endemic species from the different geographical and floristic regions of the world. The gene pool of Cornus L. s. l. in the NBG consists of more than 30 species and 40 cultivars including the insufficiently researched and little-known Californian endemic C. sessilis. In Europe, it has been grown since 2017 only in Chateau Perouse Botanic Gardens (Saint-Gilles, France) and in Ukraine only the NBG has it. In this article we evaluate the life cycle of the development C. sessilis under conditions of introduction different from the conditions of its natural area. To do this, we used the classic traditional methods of the research on the process of introduction, in particular, botanical plant identification, visual observation, phenology, comparative morphology and biometrics. Morphological descriptors (life form, colour and texture of bark, leaf shape, pubescence character, structure of generative and vegetative buds, inflorescences, flowers, fruits and endocarp) of C. sessilis genotypes introduced to the NBG are identical to those of plants from their natural habitats. The weight of fruits and endocarps were determined by us for the first time. The results of biometric analysis of the size of leaves and fruits showed that the plants of C. sessilis grown in the NBG had the larger leaf blades, but the smaller fruits as compared to those in the wild. In the NBG the plants underwent a full cycle of seasonal development (from the deployment of buds to the leaf fall, inclusive) for 229 days. In general, the phenological strategy of C. sessilis genotypes introduced in the NBG corresponds to that of other species of Cornus s. str., including C. mas L. Our results indicate that C. sessilis, California’s rare endemic species new to Ukraine, has adapted to the new conditions – the plants bear fruits and produce seeds. The experience of successful introduction makes it possible to cultivate a new species to expand the diversity of food, medicinal and reclamation plants of the family Cornaceae as well as the use in synthetic breeding to obtain new cultivars with valuable biological and economic properties. Cornus sessilis compatibility test as rootstocks for other species is important for clarifying the theoretical issues of family ties of species Cornaceae and practical – for widespread reproduction of the required cultivars C. mas breeding in the NBG on a potentially compatible rootstock C. sessilis.

Rare Plant Species

Increasing anthropogenic pressure, global climate change, and the lack of large introduction centers in the Chernihiv region makes it important to preserve rare species of flora ex situ outside this administrative region. The article presents the results of the study of taxonomic composition and evaluation of the success of the introduction of rare plant species of Chernihiv region in the M. M. Gryshko National Botanical Garden of National Academy of Sciences of Ukraine. The study of rare plant species and the development of methods for their effective reproduction was initiated in the NBG in 1970 in a separate section “Rare plants of the flora of Ukraine.” It is established that the collection grows and protects 57 phythorarites of Chernihiv region, of which 29 species are listed in the Red Book of Ukraine (III edition), and 28 species – in the “List of regionally rare plant species of Chernihiv region”. Most plants successfully recover ex situ with moderate care or without additional human intervention. The biomorphological spectrum of introduced plants is dominated by cryptophytes (50.88 %) and hemicryptophytes (42.11 %), the shares of phanerophytes, hamephytes and therophytes are insignificant. 17 species of phythorarites formed stable homeostatic populations. Of these: 5 species are listed in the Red Book of Ukraine (Allium ursinum, Crocus reticulatus, Epipactis helleborine, Galanthus nivalis, Pulsatilla pratensis) and 12 species – in the “List of regionally rare plant species of Chernihiv region” (Aster amellus, Corydalis intermedia, C. marschal, Daphne mesereum, Equisetum hyemale, Iris hungarica, Phlomis tuberosa, Primula veris, Pteridium aquilinum, Scilla bifolia, S. sibirica, Vinca minor). Thus, the cultivation of almost a third of the phythorarites of Chernihiv region in the M. M. Gryshko National Botanical Garden testifies to the effectiveness of their preservation ex situ.

This paper discusses morphological and anatomical aspects of the first-and-second-year-leaf epidermis of the two winter-green species, genus Rhododendron L.: R. catawbiense Michx. and R. davidsonianum Rehd., grown in the Bugsko-Polessky Region from the seed reproduction of the Central Botanical Garden of the National Academy of Sciences of Belarus. The representatives of the studied genus are promising crops for planting gardens, settlements and interiors. Therefore, the study of leaf anatomy lets to find plants adaptive features to different environmental conditions and identify their adaptation capacity in the new conditions of growth. The paper identified diagnostic features, as well as similarities and differences of morphometric parameters. The research method was a comparative anatomical one. The author made a code of diagnostic features of the leaf anatomical structure, which described the views of cross sections. The character of the natural confinement species lays its mark on the formation of individual elements of the leaves structure, ensuring their successful adaptation to the new conditions of growth. The studies have shown that both species quite successfully acclimatized and are promising for mass reproduction and wider use in the Bugsko-Polessky Region, and this is supported by qualitative and quantitative indicators of the morphology and internal leaf structure.

Gymnospermium odessanum is a rare relict endemic plant species. The research was carried out during G. odessanum flowering in 2019–2021 at the botanical-geographical plot “Steppes of Ukraine” of the M.M. Gryshko National Botanical Garden, National Academy of Sciences of Ukraine (NBG). Ecological and coenotic conditions of introduction at the NBG differ from natural habitats of the species and are not optimal for its vegetation. However, this species demonstrated ecological-coenotic plasticity and, over the decades, has formed a stable homeostatic introduction coenopopulation here. As of 2021, the area of introduction coenopopulation of G. odessanum at the NBG was 2,075 m2. It comprises 412 individuals of this species (including 40 seedlings, 241 juvenile, 45 immature, 40 virginal, 45 generative, and 1 sub-senile plants). Coenopopulation fragments with a high density of G. odessanum individuals are rare here, so the average density is low – only 0.2 individuals per 1 m2. In 2021, in the spectrum of age states, the total percentage of pregenerative individuals was very high and reached 88.8 %; the share of generative individuals was 10.9 %.In general, the age structure of the introduction coenopopulation of G. odessanum is characterized by long-term (2010–2021) stability. The spatial distribution of individuals in the introduction coenopopulation is of two kinds – random and in groups. This is due to combined myrmecochoric and barochoric propagation. Also due to myrmecochory, this coenopopulation tends to spread the area. Compared to natural coenopopulations, the introduction coenopopulation of G. odessanum at the NBG is characterized by a larger area, a much significant number, and, at the same time, a low average density of individuals. However, like in most of natural populations, its age spectrum is left-sided.The conducted research testifies the successful formation of the introduction coenopopulation of G. odessanum in the meadow-steppe cultural phytocoenosis of the NBG. This introduction coenopopulation is an example of a successful multi-year scientific experiment and effective ex situ protection and preservation of G. odessanum on the northern border of the Right Bank Forest-Steppe of Ukraine, far beyond the natural range of this endemic plant species.

Feverfew (Tanacetum parthenium (L.) Schultz Bip. is a perennial plant of the Aster family, which has an anti-migraine, anti-inflammatory and analgesic activity. These days studying of the feverfew varieties is actual in order to expand the raw material base because species and varieties are known to have a similar chemical composition. In Ukraine, the varieties White Gem and Phlora Pleno are widely cultivated and they are unpretentious to the natural and climatic conditions of Ukraine. The morphological and anatomical study of the selected varieties previously has not been studied, therefore this analysis is actual. The aim of the work was to conduct a morphological and anatomical analysis of the feverfew herb varieties Phlora Pleno and White Gem. The object of the study was samples of the feverfew herb varieties Phlora Pleno and White Gem collected during the period of mass flowering in 2018–2019 on experimental plots of the Botanical Garden of the National University of Pharmacy (Kharkiv, Ukraine) and the National Botanical Garden N. N. Grishka (Kiev, Ukraine.). Morphological features were examined on fresh, dry and fixed raw materials using a Levenhuk Zeno Handy ZH19 magnifier. Anatomical studies were carried out using raw materials fixed in a mixture of alcohol–glycerin–water (1:1:1) and in accordance with the requirements of the SPhU. As a result of the analysis the general and individual morphological and anatomical features of the feverfew herb varieties White Gem and Phlora Pleno were determined. The individual morphological features of the Phlora Pleno variety include white, female ray flowers up to 1.0 cm long, arranged in 2–3 rows; variety White Gem – white, female up to 0.8 cm long, located singly ray flowers. The individual anatomical features of the Phlora Pleno variety include the paracytic and anisocytic types of the stomata; single prismatic crystals and druses in the mesophyll; variety White Gem – anomocytic type of the stomata, on the epidermis of the stem – trichomes with a lobed terminal cell and glandules. For the first time a comparative morphological and anatomical analysis of the feverfew herb varieties Phlora Pleno and White Gem collected in Ukraine was carried out. The general and distinctive features of each variety, as well as their main diagnostic features, have been determined, therefore it will be used later to standardize the feverfew herb varieties Phlora Pleno and White Gem.

Aim. To compile and analyze an annotated list of autochthonous vitamin-bearing plant species of the Kiev Plateau, which according to ethnobotanical traditions are often used by the population of this region. Methods. The research was carried out in 2002–2021 in natural phytocoenoses of the Kyiv Plateau and artificial phytocoenoses of  M. M. Gryshko National Botanical Garden, National Academy of Sciences of Ukraine (NBG). Research methods are field and cameral. Dozens of locals were surveyed to find out which autochthonous vitamin-bearing plant species are most commonly used by the region's population. Latin names of plants are given according to the generally accepted taxonomy (Mosyakin & Fedoronchuk, 1999). A linear system (Golubev, 1972) was used for biomorphological analysis. The classification scheme of florocoenotypes (Kamelin, 1973) was used for ecologo-coenotic analysis. Results. An annotated list of autochthonous vitamin-bearing plant species of the Kyiv Plateau, which is frequently used by the population of the region, is given. The spectrum of families, biomorphological and ecologo-coenotic spectra, and priority of use of certain parts of plants are analyzed. Conclusions. The annotated list describes 43 species of plants belonging to 36 genera and 21 families. Rosaceae (26%) has the largest share in the spectrum of families. The biomorphological spectrum is dominated by herbaceous plants (61%), namely, herbaceous polycarpics (49%). In the ecologo-cenotic spectrum, the largest share is occupied by species of forest (42%) and meadow (33%) florocoenotypes. For practical use, the population of the region most often collects aboveground parts of plants, in particular, aboveground shoots (46%) or aboveground shoots and fruits (33%). All plant species listed in the annotated list are presented ex situ in the NBG. More than half of them (65.1%) are exhibited on the botanical-geographical plot “Steppes of Ukraine” of the NBG.

The studied was ultrasculpture of seed surface of 2 representatives of the genus Isodon (Schrad. ex Benth.) Spach from the family LamiaceaeLindl.– I. japonicus (Burman) H. Hara and I. japonicus (N. Z. Burm) Hara var. glaucocalyx (Maxim.) H. W. Li, introduced in the M. M. Gryshko National Botanical Garden National Academy of Sciences of Ukraine (Right-bank Forest-steppe). Representatives of the genus are common in the Asian region with the greatest species diversity in China; 2 species are found in the tropical regions of Africa. Screening of literary foreign sources showed that microscopic studies of the seeds of the species and variate did not occur, at least we did not find any information on this issue. This prompted us to investigate the macro- and micromorphology of the seeds. SEM was used in the work. Methodically guided by the well-known work of W. Barthlott. The descriptive part is documented photographically. As a result of the experiment, features in morphology and structure, common and distinctive features of seeds, morphological descriptions of their shape, color, primary and secondary sculpture of spermoderm are revealed. It has been established different types of external relief for species and the variete: for I. japonicus, a characteristic densely hilly relief, and for I. japonicus var. glaucocalyx– irregularly-mesh.Also revealed differences in the structure of the outer periclinal and anticlinal walls. The outer periclinal walls of the species are convex, anticlinal concave, and in the variate– concave and protruding respectively. The spermoderm of the seeds I. japonicus var. glaucocalyx is characterize by the presence of various types of papillomas in the apical region and stomatal cells, the significance and function of which still need to be further investigated. Differences in the microrelief of the seeds can be used as auxiliary diagnostic features at the species taxonomic level for plants of the genus Isodon, obtained under conditions of introduction from the seeds of the Index Seminum system.

Geographic distribution and habitat preferences of Saxicola rubicola rubicola (Linnaeus, 1766), S. maurus variegatus (S.G. Gmelin, 1774), and S. m. armenicus (Stegman, 1935) inhabiting the Caucasian Isthmus and adjacent areas are described in detail. We examined the individual, sexual, age, seasonal and geographical variations of seven main diagnostic features of both plumage and morphometrics (exactly, the length of wing and tail) using 381 skin specimens. Substantially improved diagnoses of S. m. variegatus and S. m. armenicus are provided. After a thorough examination of the materials and history of the expedition of Samuel Gmelin in 1768–1774, and his description of Parus variegatus, it was concluded that the type locality of this taxon was the vicinity of Shamakhi in Azerbaijan not Enzeli in North-Western Turkey. It is also shown the fallacy of the recently proposed attribution of the holotype of the northern subspecies S. m. variegatus to the southern taxon S. m. armenicus and synonymisation of these names, as well as the replacement of the name S. m. variegatus by its junior synonym S. m. hemrichii Ehrenberg, 1833 for the northern subspecies.
