36 PISTILS AND STAMENS 
Peas, the ovary has one locule enclosing a number of ovules. In 
A of Figure 39, showing a lengthwise section through the flower 
of the Pea, one side of the ovary wall is removed to show the 
locule with its ovules. In this particular flower of the Pea, there 
are six ovules, but other flowers might have more or fewer. In 
B of Figure 39 is shown the ovary after it becomes a mature pod. 
The pod is opened to show the seeds. Each 
seed is a developed ovule and the pod enclos- 
ing the seeds is the ovary wall much enlarged. 
Notice how the ovules and seeds compare in 
number. 
In Red Clover, shown in Figure 40, there is 
one locule and two ovules. The ovaries of 
Alfalfa have only one locule, but may have as 
many as eighteen ovules. 
In the ovary of Corn, Wheat, Oats, and 
Grasses in general, there is one locule and a 
Fia. 41.—Length-

Tomato ovaries have few or many locules which contain a large 
number of ovules. Figure 42 shows a lengthwise section of a 
Tomato ovary showing two locules and many ovules. By count-
