EXERCISE XIII. 

 The Parts of Flowers. 



We now enter upon the study of flowers. There are a 

 great many different kinds of flowers to be examined and 

 compared, even in one small neighborhood. Each one of 

 the specimens you find must be carefully observed and 

 described. An accurate description requires that you 

 should study each part by itself, and note down concern- 

 ing it all the important particulars you can discover. But 

 before you can do this you must know what parts a flower 



consists of, and what par- 

 ticulars about these parts 

 are important. 



To learn the names of 

 these parts, then, must be 

 your first object. Com- 

 pare real flowers with Fig. 

 in, which represents a 

 flower pulled apart so that 

 its main divisions may be 

 fully seen. Begin with the 

 outer leaves of a flower, 

 and compare them with 

 the lower circle of leaves 

 in the diagram, and find 

 the name of this circle. 

 Do the same for the next 

 circle, and so on, to the 

 center of your specimen. 

 Repeat this process with different flowers till you are able, 

 at once, to point out and name the four divisions of com- 

 mon flowers. 



The outer circle of green flower-leaves is named the 

 calyx. The inner circle of delicately colored flower-leaves 

 is named the corolla. When both circles have the same 



Receptacle.
