Summary After a short review of the historical development of the problem of cytoplasmic inheritance, the principles for the proof of cytoplasmic inheritance were discussed. At present the proof can be based on the maternal transmission of plasmagenes, on the missing of mendelian segregation and on the possibility of a segregation during ontogenetic development. In the following the most important possibilities for errors and their refutation onEpilobium were discussed: elimination of genotypes (examination of the elimination of gametes, zygotes, test of accidental distribution of chromosomes, crossing with tetrads), abnormal cytology (cytological investigation, crosses with hetero- and polyploids), maternal aftereffects (clone-multiplication), predetermination (exchange of nucleus by backcrossing), nuclear produced plasmagenes (contrarily acting cytoplasm and nucleus) and transmission of parasites or symbionts as virus (grafting). At the end the principles for the distinction between different cytoplasmic constituents were discussed.
