Abstract The Prodrome of French vegetation is presented from its beginning in 1996 to the publication in 2004 of the first version of the national synsystem detailed up to the level of suballiance (PVF1). Work began in 2006 to produce a second edition, called PVF2, which aims to describe 78 of the 80 classes recorded in mainland France and Corsica, up to the level of association and subassociation. So far, 19 classes have been published, five classes are ready for publication and 54 classes are under preparation. The most important classes of PVF2, especially forest classes, should be completed in 2015.
