Presented study is focused on the syntaxonomical revision and correct classification of the associations Arunco- Salicetum capreae and Filipendulo-Salicetum capreae. The associations were described by Hadač et al. (1969) from the Dolina Siedmich prameňov Valley in the Belianske Tatry Mts. The association Arunco-Salicetum capreae was emended by Šomšák (1986) by including the new subassociation from the Slovenské rudohorie Mts. Hadač et al. (1969) and Šomšák (1986) preliminarily ordered these associations within the class Querco-Fagetea, order Fagetalia, and alliance Alnion incanae. Later authors (Mucina & Maglocký 1985, Jarolímek & Šibík 2008) ordered them into two different classes. We used numerical analyses (hierarchical clustering and detrended correspondence analysis) of 1056 relevés from floristically and ecologically similar syntaxonomical units to classify the associations within higher syntaxa and to find out whether there is a reason to distinguish two associations from such a small geographic area. Based on the analysis results we merged both studied associations into one association Arunco vulgaris-Salicetum capreae Hadač et al. ex Petrášová et Jarolímek, ass. nova, which we ordered to the suballiance Alnenion glutinoso-incanae. V raziskavi smo se osredotočili na sintaksonomsko revizijo in pravilno uvrstitev asociacij Arunco-Salicetum capreae in Filipendulo-Salicetum capreae. Asociaciji so opisali Hadač et al. (1969) v dolini Dolina Siedmich prameňov v gorovju Belianske Tatry. Asociacijo Arunco-Salicetum capreae je emendiral Šomšák (1986) z vključitvijo nove subasociacije z gorovja Slovenské rudohorie. Hadač et al. (1969) in Šomšák (1986) so preliminarno uvrstili te asociacije v razred Querco-Fagetea, red Fagetalia in zvezo Alnion incanae. Kasneje so jih različni avtorji (Mucina & Maglocký 1985, Jarolímek & Šibík 2008) uvrstili v različna razreda. Za uvrstitev asociacij v višje sintaksone smo uporabili numerične analize (hierarhično kopičenje in korespondenčno analizo z odstranjenim trendom) 1056 vegetacijskih popisov floristično in ekološko podobnih sintaksonov. Želeli smo tudi ugotoviti ali je smiselno ločevati dve asociaciji na tako majhnem geografskem območju. Na osnovi rezultatov analiz smo združili obe asociaciji v Arunco vulgaris-Salicetum capreae Hadač et al. ex Petrášová et Jarolímek, ass. nova, ki smo jo uvrstili v podzvezo Alnenion glutinoso-incanae.
