Diagnose

Mediterranean calciphilous annual and ephemeroid swards and grasslands

Remarques

tra01 : The therophyte-rich dwarf-herb and low-grass communities on calcareous substrates have been relatively well studied in the Western Mediterranean (including the Tyrrhenian region), but they remain only poorly known in the Eastern Mediterranean. Only recently have some alliances have been described from Italy (Vulpio ciliatae-Crepidion neglectae Poldini 1989, Hypochoeridion achyrophori Biondi et Guerra 2008), but their syntaxonomic relationship to the Western Mediterranean units remains unclear. We may presume that phytogeographic criteria may play a major role in the syntaxonomic subdivision of this order, yet how these vegetation types are differentiated along major environmental gradients is not well understood.
