Abstract

Important agencies responsible for the invasion of alien plants to Norway by means of shipping were ballast thrown ashore from sailing ships and contaminants in imported grain. Most ballast-plants were casuals, which disappeared when the ballast traffic ceased at the time of World War I. Changes in the origin of imported grain are reflected in the grain mill flora.
