Fig. 10. Distribution of characters in F2 from the cros roseconib X pea-comb. Each 

 square is a zygote, and its appearance is shown by the word at the bottom. 



Fig. 12, shows a curious case of the same kind in the Chinese 

 Primrose Primula Sinensis. There is a modern variety with a very 

 large yellow "eye" or flush extending up over the limb of the corolla, 

 quite distinct from the small yellow pentagon characteristic of the 

 normal flower. The variety having this large yellow eye has its 

 anthers in the position proper to long-styled plants, but the style 

 itself does not reach above the anther- level, the flower being thus 

 in the condition which Darwin called "homostyled".
