[1]: Noch stets gilt der in den Schluftbemerkungen aufgefiihrte Satz „From a chemotaxo-nomic point of view, it is highly satisfying that a chemotaxonomic evaluation of Compositae performed more than 10 years ago (i. e.: In Bd. Ill der Chemotaxonomie der Pflanzen [1964]) stands the test made possible by the availability of a very large number of new facts“.
