In tlic rine lasciations tlic vco-etative cone is trans- 

 formed into an annular wall which ultimately develops 



into a smaller or larger 

 funnel. I found these 

 remarkable structures re- 

 peatedly in my cultures 

 of Veronica longifolia, 

 where they remained 

 quite small, scarcely 

 reaching a centimeter.^ 

 On the other hand I have 

 observed a funnel -like 

 structure in Pcpcroinia 

 maculosa of more than 

 a decimeter in length. - 

 Some of the best known 

 instances of ring fascia- 

 tions occur in Taraxa-

 and I have myself often
