The substance of the carpels develops into two 

 kinds of tissue; the outer half becomes fleshy with 

 numerous roundish stone cells. The inner layer of 

 each carpel is de'^'eloped into an apparatus for expell- 

 inr^ the seed. In each carpel this layer is formed in 

 two halves. These are not closed at the top, and are
