The Lamiaceae Martinov family has about 200 genera and 3500 species, distributed in all climatic zones, with the highest species diversity in the Mediterranean. There are 35 genera in Ukraine, 180 species (together with the most cultivated ones) and stabilized hybrid forms described in the species status. The most significant nomenclature changes occurred in the segregate genera Acinos Mill., Calamintha Mill., Clinopodium L., and Micromeria Benth., the species of which were included in the genus Clinopodium L. The polyphiletic genus Micromeria Benth. has undergone nomenclature changes and a significant part of its taxa is excluded from the genus (African species are included in the genus Saturea L.). A number of these species, among which Micromeria serpyllifolia (M.Bieb.) Boiss. represented in Ukraine, included in the genus Clinopodium L., as well as in some other related genera. The genus Majorana Mill. included in the Origanum L. genus. Species of the genus Phlomis L. considered within two genera: Phlomis and Phlomoides Moench, many of which, described from the territory of Ukraine, and treated as synonyms. The genus Rosmarinus L. (R. officinalis L.) is included in the genus Salvia L. For each species, its distribution in Ukraine indicated, and the notes provide data on their variability and taxonomic affiliation.

The results of monitoring of the spontaneous vegetation in several leading institutions of the Right Bank of Ukraine are presented. It is M.M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine (Kyiv), State Dendrological Park «Oleksandriya» of the National Academy of Sciences of Ukraine (Bila Tserkva) and Syretsky Dendrological Park of National Importance (Kyiv). The studies were conducted in 2020–2021. 82 new taxa (species and subspecies) was found in the wild on the territory of the M.M. Gryshko National Botanical Garden. Currently, the historical spontaneous flora of the garden includes 730 taxa (species and subspecies), of which 418 – native, 173 – escaped plants, 139 – xenophytes. Rare native plants Hieracium sabaudum subsp. virgultorum, Pilosella plicatula, Taraxacum scanicum, Tragopogon ucrainicus were found during the monitoring of the habitats. Dysphania ambrosioides, Epilobium ciliatum subsp. adenocaulon, Erechtites hieracifolia, Erigeron strigosus, Euphorbia maculata, Hordeum bulbosum, Lamium amplexicaule var. orientale were important as progressive xenophytes. Arum elongatum, A. maculatum, Castanea sativa, Muscari armeniacum, Ornithogalum boucheanum has high rates of naturalization as a new ergasiophytes. For the first time, there are information on at least 20 introduced plants that have spread outside the botanical garden to the adjacent territories of Kyiv. Eighteen new taxa, including the endemic species Myosotis ucrainica, have been identified in the territory of park «Oleksandriya». According to new data, the wild flora of the arboretum includes 850 taxa, of which 581 native and 269 alien. Four species that were considered extinct were identified. Two natural habitats the Red Book species Neottia nidus-avis and Stipa pennata were found. There are information about mainly adventive plants in the spontaneous flora for the Syretsky Dendrological Park. Eleven tree ergasiophytes were found in the valley of the Kuryachy Brid stream near the Syretsky Dendrological Park. Among them, Fagus sylvatica, Lonicera xylosteum, Rubus occidentalis, Taxus baccata are extremely important for future monitoring.

The flora of vascular plants of old cemeteries in the city of Kherson (in southern Ukraine) includes 227 species belonging to 160 genera, 57 families, 3 classes and 2 divisions. The research was conducted during 2020–2021. In total, 3 cemeteries were studied: Kherson Memorial Cemetery (10.4509 ha), Jewish Cemetery (2.5783 ha) and Zabalkivskyi Cemetery (9.486 ha). Species richness varies from 172 to 202 (with an average of 190 species) in the different cemeteries. Leading in the number of species are the families Asteraceae (33 species), Poaceae (25), Fabaceae (15), Rosaceae (13), Chenopodiaceae (11), Brassicaceae (9), Boraginaceae (8), Caryophyllaceae (6), Lamiaceae (6), Veronicaceae (6). The systematic structure of the flora is typical for steppe flora, which are under significant anthropogenic pressure. The spectrum of life forms is dominated by therophytes (45.2 %). Most therophytes are alien plants, which indicates that this structure of the flora is the result of significant anthropogenic transformation. On the other hand, hemicryptophytes, which dominate in natural steppe flora, take second place (23.2 %) in the investigated cemeteries. Compared to rural cemeteries, the cemeteries of the city of Kherson are characterized by a higher level of sinatropization of flora. Almost half of the flora species are alien (49 %). Despite the high anthropogenic pressure of the urban environment, the flora of the old cemeteries in Kherson is still dominated by aboriginal plants (51 %). Also, there are many non-synatropic plant species (17.1 %), and several rare plant species have survived. In total, seven protected species of vascular plants (3.1 %) were found in the old cemeteries. Among them are Stipa capillata, included in the Red Book of Ukraine, and Convallaria majalis, Ephedra distachya, Fraxinus excelsior, Quercus robur, Muscari neglectum, Vinca herbacea, which are in the Red List of Kherson region. Given the environmental value of old cemeteries, it is necessary to optimize their use.

Tubifera dudkae is a rare species, described in 2011. Literature data on its distribution are limited to Ukraine (typical locality), France and Russia. At the same time, the species has a recognizable morphology and bright color of fruiting bodies, images of which can often be found on web resources related to citizen (amateur) science. The aim of this study was to accumulate all available data on findings of T. dudkae, collected by amateur activists and to combine them with information collected by professional mycologists. The study was based on specimens stored in the CWP Scientific Herbarium, as well as illustrative materials, that can be identified to the level of the species, distributed in various online sources (GBIF, iNaturalist, UrkBIN) or sent to the author by professional amateurs. A search for information about findings of T. dudkae in publicly available sources showed the presence of references to the species, but mostly with incorrect identifications. At the same time, we have found high-quality images of T. dudkae on resources like MycoWeb, www.dziedava.lv and in the Slime Mold Identification & Appreciation group on Facebook. A total of 23 observations from 20 localities of T. dudkae were identified, 16 of which are new. Citizen scientists provided first data about distribution of T. dudkae in Netherlands, Latvia and Sweden. According to the data obtained, T. dudkae is distributed in Europe and North-West Asia in a fairly wide range of climatic conditions, from the Mediterranean (Crimea, Cote d'Azur) to the zone of mixed forests (southern Scandinavia, Moscow region). Substrate preferences of the species are also relatively broad: it occurs on dead wood of oak, pine, spruce, bare or covered with mosses and lichens, and even on fallen conifer needles. Thus, T. dudkae gives the impression of a species with a wide range of ecological tolerance. The analyzed data indicate that it is distributed in a Euro-Siberian area.

The first data on the lichens and lichenicolous fungi of Kivertsy National Natural Park «Tsumanska Pushcha» are reported. Totally, 50 species of lichens and one lichenicolous fungus were found. Among them, Acrocordia gemmata, Arthonia radiata, Athallia pyracea, Biatora chrysantha, Catillaria nigroclavata, Chaenotheca phaeocephala, Cladonia cariosa, C. coniocraea, Coppinsidea croatica, Heterocephalacria physciacearum Graphis scripta, Lecaniella naegelii, Lecanora expallens, Lepra albescens, L. amara, Lepraria incana, L. finkii, Mycobilimbia epixanthoides, Phlyctis argena, Peltigera didactyla, Porina aenea, Physcia tenella, Placynthiella uliginosa, Polyozosia persimilis, P. sambuci, Pseudoschismatomma rufescens, Rinodina freyi, Scoliciosporum sarothamni are new to the Volyn region. Coppinsidea croatica is recorded for the first time for the lowland part of Ukraine. Rinodina freyi are new for Ukraine. This species is common in the forest areas of Asia, Europe and North America. It is a pioneer lichen on thin twigs of shrubs or damaged areas (scars) on the bark of trees. Rinodina freyi is characterized by a thin, almost inconspicuous gray thallus with flat areolas and negative reactions to chemical tests, sessile apothecia 0.4–0.7 µm in diameter with a grayish-brown thalline margin (50–70 μm thick), and Physcia-type ascospores 15–19 × 6.5–8.5 µm. Lichen communities are presented mainly by epiphytic species that grow on the bark of Alnus incana, Quercus robur, Salix fragilis. Low number of species were found sandy soil of river terraces. Acrocordia gemmata is a species that was included in the regional Red List of the Volyn region.
