5. The Ratio of the Breadth to the Length of the Corolla. 
The parent plants differed markedly in the relative width of the corolla. C (1), 
C (2) and N (1) were wide, B (1), B (3) and B (4) were narrow, and the remainder 
were of medium width. As in the case of the amount of spotting of the corolla, 
no distinct discontinuity in the variation of the character could be noticed either 
in the parents or offspring. As far as could be judged the variation was a con- 
tinuous one, or one with such small steps as practically to be equivalent to the 
same. 
The following tables of correlation are given as records: 
Ratio, Mid-parent and Offspring [excluding self-fertilized Families).
