From the point of view of plant geography, including various aspects of chorology, one of the prerequisites of successful large-scale synthesis of this type is and adequate flora covering the area in question, and providing a common language in respect to the delimitation and nomenclature of the taxa to be treated. This essential conditon is now fulfilled for Europe by the current volumes of Flora Europaeae. This new series of compendium atlas volumes makes available allthe distribution maps so far produced by the commitee for mapping the flora of Europe in convenient library editons and in the format and livery of Flora Europaeae. A thirds volume containing the caryophllacaeae is in preparation.
