THE FKTJIT AND SEED. 103 



Now examine an apple or pear. What do you 

 find at the top of the fruit, opposite the peduncle ? 

 It must be the remains of the calyx-limb, the tube of 

 which you saw united to the pistil when you studied 

 it in flowering-time. Of what, then, does the fruit 

 consist? Divide an apple or pear, as shown in Fig. 

 212. Find the parts shown in this diagram. The re- 



M 



mains of the flower are seen at C. The calyx-tube, 

 grown fleshy and succulent, is marked T. The outer 

 border of the ovary is seen at E. From what part 

 of the flower is the eatable portion of a pear or apple 

 developed? To repeat our former question, would 

 the fruit of a superior pistil be more likely than that 

 of an inferior pistil to consist of the ovary alone ? 



I have illustrated the composition of fruit with 

 apples and cherries because they are so common ; but 

 these observations may, and should be, repeated upon 

 every variety of fruit that can be found. 



Trace the formation of each of the fruits pictured 

 upon the charts, and point out those that consist of 

 the pistil alone, and those which do not. In the lat- 

 ter case, name the parts that are consolidated with 

 the pistil in the fruit.
