The plant community diversity, species composition and community structure of rare thermophilic plant communities and aggregations of Nizhne-Tchazhminsky hot springs (Kronotsky Nature Reserve, Eastern Kamchatka) were studied. A number of rare and endangered species of vascular plants were revealed in the area of the hot springs. The horizontal structure of the plant cover was studied. In accordance with the temperature and moisture of the substrate, several vegetation microzones were distinguished.

In the article, herbarium collections of adventive monocotyledon plants of Institute of Biology of the Komi Science Centre of the Ural Division RAS (SYKO) and Pitirim Sorokin Syktyvkar State University (SYKT) are published. The authors showed that since the 30-ies of the 20th century 50 species (or 46 taking into account a wider interpretation of species Typha) of adventive plants from four families were found on the territory of the Republic of Komi. Seven species (Typha incana, T. laxmannii, Anisantha sterilis, Bromus danthoniae, Holcus lanatus, Hordeum leporinum) are picked up only once or twice at the same place (Alisma lanceolatum). Other 11 species (Typha elata, Aegilops cylindrica, Anisantha tectorum, Avena strigosa, Beckmannia syzigachne, Elymus sibiricus, Hordeum murinum, Lolium remotum, Phleum nodosum, Setaria italica, S. pumila, Sorghum halepense ) are gathered in different places of the Republic, but there are no repeated finds for location. The structure of finds is similar for the following 10 species (Typha intermedia, T. linnaei, Alopecurus myosuroides, Bromus japonicus, Hordeum distichon, H. vulgare, Lolium multiflorum, L. temulentum, Phalaris canariensis, Phleum phleoides ), but they have more massive collections. Finds of 13 species of cultivated plants and weeds (Agropyron cristatum, Avena fatua, A. sativa, Bromus arvensis, B. mollis, B. squarrosus, Echinochloa crusgalli, Hordeum brevisubulatum, H. jubatum, Lolium perenne, Panicum miliaceum, Secale cereale, Triticum aestivum) were relatively abundant until 90-ies of the 20th century then they stop. Properly massive and permanent collections are characteristic only for two plants – Elodea canadensis, Typha latifolia s. str. They successfully infiltrated natural or anthropogenicallytransformed reservoirs of the Republic and are currently expanding their areas. In addition, the collections of Alopecurus geniculatus , Poa compressa and Setaria viridis are relatively abundant and constant until the end of the 20th century. Absence of new finds of these species is difficult to explain.

The article gives a detailed checklist of the flora of monocotyledonous plants of Sverdlovsk region, based on the long-term field researches, critical study of herbarium materials and literary sources. A brief history of the study of the vegeta-tion cover of the region is given. Information is provided on the distribution, bio-ecological features and economic significance of 394 species, 12 subspecies and 13 interspecies hybrids of monocotyledonous plants of the natural flora of the region. Species in need of protection are indicated, as well as species widely cultivated on the territory of the region, were noted.

An annotated list of rare species of the Southern Opillya (Western Ukraine) flora is presented. It comprises 259 species of vascular plants. The majority of rare species are protected at international, national and regional scales. The present study analyzes the occurrence and population size of rare species. The total number of populations found is 1900; 74.6% of them was estimated. More than a half these populations (53.3%) are small including from a few to a hundred individuals. Most species have rare occurrence, 59.1% out of which are known from 1-5 localities. Species growing in more than 20 localities comprise only 7.3% of the rare flora. Bot-rychium multifidum, Gymnadenia odoratissima, Ophrys insectifera, Tofieldia calycu-lata, Salix starkeana, Viola palustris, V. uliginosa, Leersia aryzoides are likely to be-come extinct in the Southern Opillya.

Ophioglossum vulgatum L. on the White Sea is common on the coastal meadows. Analysis of the formulas of amplitude ecological characteristics of species of these meadows by scales of L.G. Ramenskij (1956) revealed the existence of two groups of species with contrasting ecology. In this case, there is a layering of soil salt: desalination of its upper horizon and the occurrence of salt in a small rooting depth. For O. vulgatum such meadows are favorable lack of shading and strong root competi-tion of other species.
