ST M MARY OF VARIATIONS. 



When in full bloom the petals vary in color from typical white 

 or pink, through white with green centre stripe to solid green. 

 Those petals which are entirely green usually persist on the plant 

 regardless of the presence or absence of leaves, and in those which 

 are merely white-margined the green portions usually persist 

 after the white parts have withered. Such persistent petals, the 

 sepals and the leaves, gradually become purplish-brown in color, 

 remaining thus colored until the plant withers to the ground. 

 Usually by the time the carpels of the normal plants have attained 

 their full size all traces of the abnormal plants have disappeared. 

 The following figures will show the limits of variation in size 

 of the different parts of the plants which have been tabulated :
