New syntaxa of different hierarchical levels are here described in order to update the “Syntaxonomic checklist of the Italian classes, orders and alliances (Vegetation Prodrome of Italy)”, promoted in 2012 by the “Ministry of Environment, Land and Sea Protection” in collaboration with the “Italian Society of Botany”. The new alliances, suballiances and associations belong to the Salici purpureae-Populetea nigrae and Querco roboris-Fagetea sylvaticae classes.
