ABSTRACT Aims The class Crypsietea aculeatae comprises pioneer ephemeral dwarf‐graminoid vegetation occurring in periodically flooded saline habitats. Although numerous regional studies have described this vegetation, a unified classification across Europe has been lacking. This study aims to establish a formalized, continent‐wide classification at the association level, identify its biogeographical patterns, and assess relationships between species composition and environmental gradients. Location Europe (except Armenia, Azerbaijan, Georgia, and Russia). Methods We compiled a dataset of 2538 vegetation plots from the European Vegetation Archive (EVA), private databases, and literature. A hierarchical expert system was developed using formal definitions of syntaxa based on species cover. Nonmetric multidimensional scaling ( NMDS ) was applied to evaluate compositional differences and reveal biogeographical patterns. Distance‐based redundancy analysis (db‐ RDA ) and unweighted community means of Ellenberg‐type indicator values ( EIVs ) were used to assess environmental drivers. Results We present a revised syntaxonomic framework for the class Crypsietea aculeatae and propose updates to the EuroVegChecklist . One alliance ( Cypero‐Spergularion marinae ) and four associations ( Crypsietum aculeatae , Crypsietum schoenoidis , Cyperetum pannonici , and Oxybasio chenopodioidis‐Crypsietum aculeatae ) were formally defined, with basic descriptions of their species composition, ecolog...
