34 PISTILS AND STAMENS 
ing the ovary and stigma, known as the style. In the pistil of the 
Cherry shown in Figure 35 the parts are indicated. The ovary is 
ato. The stigma is the expanded surface at st. The style is at s 
and is a stalk-like structure projecting from 
the ovary and supporting the stigma. 
In the Corn the style is extremely long and 
the stigma branched. (F7g. 36.) In Wheat, 
Oats, Barley, and Rice there are two very 
short styles and the stigmas are much 
branched and plume-like. (Fig. 37.) Styles 
and stigmas vary much among plants. 
Ovary. — The ovary is the most impor- 
tant part of the pistil because within it the 
seeds are produced, and often it makes the 
edible portion of fruits.

When the ovary is sectioned so that its interior may be studied, 
it is seen that it is not a solid body, but consists of a wall 
enclosing one or more cavities, valled locules. (Fig. 38.) In 
these cavities or locules are the small bodies called ovules, each 
of which is capable of developing into a seed. Point out the 
parts of the ovary shown in Figure 38. 
The ovary may contain one locule or many and the number of 
ovules in a locule also varies in different ovaries. In Beans and
