THE FRUIT 



255. Sectioii of a Peach. 



calyx tube completely incorporated with it, as in the Goose- 

 berry and Pear (Fig. 259). 



Aggregate, when a cluster of carpels of the same flower 

 are crowded into a mass ; as in 

 Raspberries and Blackberries (Fig. 

 256). 



Accessory, when the surroundings 

 or supports of the pistil make up 

 a part of the mass. In an accessory 

 fruit such as the Strawberry the great 

 mass is receptacle (Fig. 156). 



Multiple or collective, when formed 



from several flowers consolidated into one mass, of which 



the common receptacle or axis of 



inflorescence, the floral enve- 

 lopes, and even the bracts, etc., 



make a part. A Mulberry (Fig. 



257, which superficially much 



resembles a Blackberry) is of 



this multiple sort. A Pineapple 



is another example. 



Stone fruits, or drupaceous 



(Fig. 255), the outer part fleshy 



like a berry, the inner hard or 



stony, like a nut ; and 



Dry fruits (Fig. 266), those 257 



which have no flesh or pulp. 



314. In reference to the splitting apart of the pericarp 

 for the liberation of the seeds, fruits are said to be 



Dehiscent, when they open regularly along certain lines. 

 A dehiscent fruit almost always contains many or several 

 seeds, or at least more than one seed (Fig. 267). 



Indehiscent, when they do not open at maturity. Fleshy 

 fruits and stone fruits are of course indehiscent. The 

 seed becomes free only through decay or by being fed 

 upon by animals. Of dry fruits also many are indehiscent. 



315. The principal kinds of fruits which have received 

 distinctive names are the following : 



257 



256. Aggregate fruit of the 

 Blackberry : consisting 

 of a number of ripened 

 pistils crowded on a 

 fleshy receptacle. At 

 the right, one of the in- 

 dividual fruits (a drupe) 

 further enlarged. 

 Multiple fruit of the Mul- 

 berry.
