DISCUSSION. 



The simple Mendelian behavior of the ramose character in the 

 earlier experiments indicated that the present unbranched form of 

 pistillate inflorescence and the reduced number of branches in the 

 staminate inflorescence were the result of a single major genetic 

 change. The variability of the ramose segregates from the Ramosa- 

 Gordo hybrids indicates that the evolution, of the ear from a 

 branched inflorescence was a gradual process. That the branching 

 tendency of the staminate and pistillate inflorescences can be sepa- 

 rated indicates that the two inflorescences did not undergo change at 

 the same time, and from the general ab.sence of branches on ears it 

 would seem reasonable to infer that the transformation from
