SP:CTI0N VII. STUDY OF FRUITS (VARIOUS FRUITS) 



General statement. The various fruits in the Fall Fruits 

 Exercise are to be referred to, but the exercises here given 

 take up the subject more specifically and with greater detail. 

 The fruit definition should be ever before the student, viz. : 

 A seed-plant structure, consisting of the ripened ovary 

 alone or with its attached or adjacent flower parts, the pur- 

 pose of the whole being, first, protection to the seed, and 

 finally seed dissemination. Many fruits also furnish food 

 for the successful seed growth. 



Types. There are many types, each characterized by the 

 possession of certain peculiarities of size, form, and structure, 

 but all are separated into dry and fleshy (or 2mlpy) fruits, 

 according to the amount of fluid they contain when ripe. 

 Fruits again may open spontaneously (are dehiscent) by valves 

 or 2^ores, discharging the seed, or the latter may only escape 

 by the decay of the fruit {indehi scent). 



The following types are named with a common example 

 of each. Each of these examples should be carefully 

 studied externally and in section and a set of characteristics 

 formulated. 



Drawings should be made to show the result of the study.
