Geographical distribution, habitats and modern state of Carlina cirsioides (Asteraceae) populations

The study of the current state and habitats rare threatened species plants is a relevant task ecological research. paper presents results systematic position, modern populations included in Red DataBook Ukraine Carlina cirsioides Klokov (=C. acaulis L.). well-known to European phytosozologists as an endemic relic Flora Ukraine. At same time, independence this taxon not recognized by authors monographs on genus “Flora Europaea”. Comparative morphological, chorological ecological-coenotic analyses do give sufficient reasons consider C. described separate species, According morphological traits, specimens from lowland part belong caulescens subspecies, which distributed mostly lowlaand regions Europe. Ecological-coenotic conditions plains are different those mountain close Central Steppe communities class Festuco-Brometea, component Ukraine, xerothermic herbaceous Europe; forest Erico-Pinetea with Ukrainian Polissia North-East Poland very сlose floristic composition. removal status near eastern border range does at all downplay its sozological significance. Taking into account low number Volhynian-Podolian Upland Polesian Lowland, localities must be taken under protection situ.
