The body of basic knowledge of vascular plants has increased rapidly inrecent decennia, and the taxonomical and geobotanical informationscattered throughout the world in innumberable herbaria and botanicalpapers urgently requires synthesis at international or continental level. From the point of plant geography, including various aspects ofchorology, one of the prerequisites of a successful large-scale synthesis of this type is an adequate flora covering the area in question, and providing a common language in respect of the delimitationand nomenclature of the taxa to be treated. This essential condition isnow fulfilled for Europe by the current volumes of 'Flora Europaea'. Sofar only a small number of European taxa of vascular plants has beensatisfactorily mapped. - The Atlas is being issued by a numerous staffof international researchers, including Meusel, Ellenberg,Faegri, Tolmachev and many others leading in plant geography. FloraEuropaea is followed, whenever possible, as to species (and subspecies),and nomenclature. The area mapped is that of Flora Europaea. The Azoresand Spitsbergen appear as insets. Mapping unit is the 50 km square ofthe UTM grid map, scale 1:1 Million. Europe comprises approx. 4400squares.
