io EXAMINATION OF [CHAP. 



LEAVES. These, we have found, are of five different 

 kinds. First are the radical and cauline 



(i.) Foliage-leaves, called simply LEAVES.* Then come 

 the flowers, terminating the stem and its branches, con- 

 sisting of 



(2.) Calyx-leaves, called SEPALS. 



(3.) Corolla-leaves, called PETALS. 



(4.) Staminal-leaves, called STAMENS. 



(5.) Carpellary-leaves, called CARPELS. 



* In many plants we may distinguish two modifications of 

 the leaf below the flower-leaves, besides the green foliage-leaves ; 

 but as it is not important to distinguish these in the buttercup, 

 we shall pass them by at present.
