nity lias been preseuted for favorable hybridizing, and in 



the repeated replant- 

 ing of these seed year 

 after year, the types 

 have been well estab- 

 lished. It becomes, 

 therefore, a difficult 

 problem to determine 

 from what kind of 

 species the individuals 

 are derived. Investi- 

 gations will be con- 

 tinued on this line and 

 it is hoped that future 

 results will warrant a 

 more decided answer 

 to the problem.

leaves grown on the plants cultivated at Auburn 'for our 



experiments, and they 

 also represent the 

 number of sjDecies. It 

 may not be far wrong 

 to say that they also 

 give us the majority, 

 if not all, the types 

 grown in the South. 

 If this position is cor- 

 rect these leaves will 

 be of some interest in 

 enabling us to answer 

 the problem concern- 

 ing the number of 

 species now found in 

 the cotton belt. jjj^jy^it^jt^L
