 Princess Beatrice (cream), Pink Perfection (pink). 



Male. — Cor., colour various ; form greatly enlarged ; anthers 

 deep crimson. 



Female. — Cor., colour. The effect of the white female parent 

 is to dissociate the yellow from the red in the scarlet-crimson of 

 the male parent. This is completely effected in Virgil (primrose), 

 which has pink anthers. The yellow is a restoration from the 

 grandparent, B. Brooheanum. On the other hand the yellow 

 is totally eliminated in Pink Perfection.
