seen today in the white Water Lily, where con- 
centric rows of stamens gradually merge into 
petals. Double Roses and Poppies are exam- 
ples of the same thing.

to the plant. Once he is there, means must be 
found to make sure that he performs the mar- 
riage duties assigned to him. Each flower 
takes care of this problem in a different way.
