The relative activities of seven gibberellins have been tested in their ability to induce antheridia in prothallia of Anemia phyllitidis. The spectrum of activities differs from the spectra described for other gibberellin reactions. Allogibberic acid proved to be highly active m the Anemia test. Additionally it causes a change in the polarity of the germinating spore. Under the influence of this compound the primary rhizoid is transformed into an additional chloronema. In high concentrations of allogibberic acid more than 80% of the prothallia develop into those "twins". Out of the polypodiaceous ferns only few species respond to gibberellin application. The relations between chemical structure and activity of different gibberellins are discussed.
