The purpose of the present paper are: a) to show the synusial structure of the herb layer of ten sities, located in Norway, Finland, Estonia, Latvia, Lithuania and Poland along the transect, and b) to characterize the species-area curves for all the sities studied. The number of types of synusiae on the particular sities ranges from three to ten, though only one or two have the dominating character, that is, occupy at least 20 percent of surface. From the point of view of synusial differentiation three geographical groups of sities could be estabilished
