Historical (mainly 1930s) and contemporary records of 482 vascular plant species or genus of non-littoral areas of 464 islands in the archipelago of SW Finland are compared to visualise changes in distribution patterns, and to identify environmental variables that exert an influence on the distribution of the species. The environmental variables were measured in a GIS. Logistic regression analysis was used to find variables that exert an influence on the probability of species occurrences. In this second part of a series of papers results, including distribution maps, are presented for species of Pinaceae, Cupressaceae, Nymphaeaceae, Ranunculaceae, Papaveraceae, Ulmaceae, Cannabaceae, Urticaceae, Fagaceae, Betulaceae, Myricaceae, Caryophyllaceae, Chenopodiaceae and Polygonaceae. A synthesis of the study will be presented in the last part of this article series.
