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.
