The Adenostylion alliariae alliance (Mulgedio-Aconitetea class) comprises plant communities which grow optimally in the subalpine zone of the European mountain ranges. The flora of these communities consists of more than four hundred taxa of vascular plants. Some of the diagnostic species are valuable and rare, either in the Carpathians as a whole or in the countries in which the Carpathians lie. In the flora of the plant communities studied, five taxa are indexed in the Polish Red Book of Endangered Plant Species, thirteen taxa are endemic to the Carpathians, and fourteen represent the eastern biogeographical element in the Polish flora. Two taxa are listed in the Annex II of the Habitats Directive.
