CORN SELF-POLLINATED AND 

 CROSSED WITH TEOSINTE 



The upper ear is an ordinary ear of 

 sweet corn, presenting no marked pecu- 

 liarities. The lower ear was developed 

 on the same stalk by pollenizing the 

 corn silk with pollen from the primitive 

 type of corn called teosinte, which is 

 illustrated on earlier pages of the 

 present volume. The influence of the 

 pollen parent is clearly shown in the 

 modified form of the kernels. With 

 most plants the pollen does not directly 

 affect the fruit, but corn is a notable 

 exception in this regard.
