226 FOUNDATIONS OF BOTANY 



247. Accessory Fruits and Multiple Fruits. Not infre- 

 quently, as in the strawberry (Fig. 172), the main bulk of 

 the so-called fruit consists neither of the ripened ovary 

 nor its appendages. Such a combination is called an 

 accessory fruit. 



Examine with a magnifying glass the surface of a small, unripe 

 strawberry, then that of a ripe one, and finally a section of a ripe 

 one, and decide where the separate fruits of the strawberry are found, 

 what kind of fruits they are, and of what the main bulk of the straw- 

 berry consists. 



The fruits of two or more separate flowers may blend 

 into a single mass, which is known as a multiple fruit. 

 Perhaps the best-known edible examples of this are the

mulberry (Fig. 172) and the pineapple. The last-named 

 fruit is an excellent instance of the seedless condition 

 which not infrequently results from long-continued culti- 

 vation. 



248. Summary. The student may find it easier to 

 retain what knowledge he has gained in regard to fruits if 

 he copies the following synopsis of the classification of 

 fruits, and gives an example of each kind.
