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.
