How, then, can we explain the origin of umbella by various repre- 

 sentatives, if the plant is not an entomophical one and has no 

 need of the solution of the .,Auffäligkeitspr oblem'-? Ч As 

 answer I shall quote the words of A. Kerne r: ,,Die Bedeutung der 

 gedrängten Blutenstände ganz vorzüglich in dem Zustandekommen 

 der Kreuzung benachbarter Blüten eines Stockes liegt" ^. As it 

 seems, the origin of primary forms of „Umbellifer ae", without 

 stylopodium and disc, must also be taken for having a causal 

 connection with g e u t о n о g a m y. The considerable length of the 

 styles also shows undoubtedly the same modus of pollination. 



In conclusion, I desire to express my sincere thanks to Prof. 

 Dr. M. G ol en kin under whose supervision the work has been 

 carried on.
