Nor is the hornbeam (Oarpinus betulus) mapped. On the whole it followed in time and space the beech (Fagus.silvatica).Map f shows the distribution and, to some degree, the standard of pollen-analytical investigations in Sweden. The hatchedareas cover the sites from which pollen-analytical results, mostly as pollen diagrams, are published or will be published inthe near future. (Several unpublished pollen diagrams are kept in the archive of Sveriges Geologiska Unders6kning(SGU), Stoekholm 50.) The dots in South Sweden indicate the sites for the series of pollen diagrams presented by VONPosT in 1916 at the Scandinavian scientists' meeting in Kristiania (Oslo). The limits of distribution of oak and spruce,drawn schematically on the map, divide Sweden into three main forest regions below the alpine (black on the map) andsubalpine belts, viz. from south to north: (1) deciduous-tree forest region with beech, (2) conifer-forest region withthermophilous deciduous trees (partly without beech), and (3) conifer-forest region, mainly without thermophilousdeciduous trees.The presentation of the old shorelines and the extension of the land-ice is mainly based on maps by GRANLUND andFROMM (in G. LUNDQVIST 1963a) and by G. LuNDQVIST (1961).Acta Phytogeogr. Suec. 50
