ILLUSTRATED TERMS. 



Self-Fertilization occurs when the stigma receives the 

 pollen from the stamens in the same flower-cup as itself. It is 

 not regarded as being as generally beneficial as when cross- 

 fertijization takes place ; and to prevent it, flowers are often 

 most ingeniously devised. 



The arrangement of the fruit on the stem is naturally the 

 same as that of the flower, and to describe it the same terms 

 are used. 



The fruit is in reality the ripened ovary which contains the 

 seeds. 



Fleshy Fruits are those in which, as they grow, the ovary 

 becomes fleshy or pulpy. Berries are fleshy fruits.

A Pome is a fleshy fruit. In it the calyx-tube adheres to 

 the ovary and forms of the fruit the greater part. Both in 

 pears and apples, which serve for illustrations, the pods of the 

 core are the only parts of the original pistil. 



Stone Fruits are those which are partly fleshy and partly 

 hard.
