Chemodiversity, as a new research concept, is highlighted by a discussion of selected publications of Professor Dr E. Wollenweber. Excretion phenomena of flavonoid aglycones are addressed, such as localization, chemosystematic, and applied aspects. Various classes of flavonoids have been reported from exudates; even flavonoid glycosides and biflavonoids were accumulated on the leaf surfaces of plants. The production of other exudate constituents outside the flavonoid pathway is briefly addressed. The connective role to biological disciplines is stressed, particularly as far as secretory structures are concerned.
