The distribution maps are custom-made. The maps for Germany are mainly based on data from the Bundesamt für Naturschutz (BfN) und Netzwerk Phytodiversität Deutschland (NetPhyD) (2013. The european maps are mainly based on data from the Euro+Med-database (Euro+Med 2006).

The colours represent the floristic status of the species in the respective region. Green indicates native occurrences, light green naturalized occurrences. Adventive occurrences are represented by light yellow shades and plants that are cultivated (but rarely occur in the wild) are dark yellow. Grey colours are used, if the floristic status of species is unknown or uncertain.
