A total of 546 releves collected in western Bulgaria and referred to Festuco-Brometea were classified into the alliances Festucion valesiacae, Saturejion montanae, Cirsio-Brachypodion pinnati and Chrysopogono-Danthonion calycinae. All releves assigned to alliance Cirsio-Brachypodion pinnati were further classified towards lower level which resulted in the description of a new association - Hieracio pilosellae-Festucetum dalmaticae and two new subassociations added to ass. Galio lovcense-Artemisietum chamaemelifoliae. Both associations were ecologically well differentiated on the basis of soil parameters (pH and humus content) as well as some additional factors (exposition, land use, etc.). V zahodni Bolgariji smo naredili 546 vegetacijskih popisov, ki jih uvrščamo v razred Festuco-Brometea in dalje v zveze Festucion valesiacae, Saturejion montanae, Cirsio-Brachypodion pinnati in Chrysopogono-Danthonion calycinae. Vse popise, ki smo jih uvrstili v zvezo Cirsio-Brachypodion pinnati smo členili na nižje sintaksonomske enote. Opisali smo novo asociacijo - Hieracio pilosellae-Festucetum dalmaticae in dodali dve novi subasociaciji k asociaciji Galio lovcense-Artemisietum chamaemelifoliae. Obe asociaciji sta ekološko jasno ločeni na podlagi talnih parametrov (pH in vsebnost humusa) in nekaterih dodatnih dejavnikov (ekspozicija, raba tal, itd.).
