than one pistil. The corolla marked "cor" is in the 

 cherry and most flowers the colored part. In the cherry 

 it has five divisions called petals. The stamens are 

 marked (S). The enlarged part at the top is the anther 

 containing the pollen. The slender part connecting the 

 anther with the calyx is called the filament.

33. Inferior and Superior Flowers. In horticulture the 

 flowers of the orchard fruits are divided into two classes, 

 known as inferior and superior. 



The cherry and peach are superior in formation, as the 

 fruit forms above the calyx, as shown in Fig. 13. In this 

 case the fruit is developed by growth and alteration of the 

 sides of the ovary and other parts of the pistil in the 

 cherry, often leaving the calyx on the stem of the fruit. 

 In the apple and pear the pistil and calyx grow together 

 and the fruit is practically an enlargement of the whole 

 flower, as shown in the divided flower of the apple at 

 Fig. 14. 



In this class of fruits the calyx is shown at the eye of 

 the fruit, while in the cherry it shows at the lower end of 

 the stem.
