Borhidi 1996 is a characteristic association of the calcareous sandy areas of the Pannonian basin; its dominant grass species is <em>Festuca vaginata</em>. Another typical species of these sandy areas is the newly discovered <em>F.</em><em> pseudovaginata</em>. The question is whether <em>F. pseudovaginata</em> forms an independent coenotaxa? Our study proved that <em>F. vaginata</em> and <em>F. pseudovaginata</em> populations grow separately and compose different associations. Stands dominated by <em>F. pseudovaginata </em>had a higher species richness and harboured twice as many <em>Festuca-Brometea</em> species compared to the <em>Festucetum vaginatae</em> stands. Diagnostic species of the <em>Festucetum pseudovaginatae </em>association are <em>Festuca pseudovaginata, Colchicum arenarium, Ephedra distachya</em>, <em>Koeleria majoriflora, </em>and <em>Astragalus onobrychis</em>. The number of species, the density of the individuals, and the variability and diversity of the vegetation separated it from the <em>Festucetum vaginatae </em>association; thus, it can be considered an independent endemic association. <em>Festucetum pseudovaginatae</em> has its own differentiating and dominant species: <em>Carex stenophylla</em>,<em> Cynodon dactylon</em>,<em> Eryngium campestre</em>,<em> Kochia laniflora</em>.</p> ER -
