Parts of the Flower . 
The study of forms in the flower will give you 
more to observe than all the other parts of the plant 
put together. There are a good many different parts 
that go to the making of a complete flower. And the 
names of all these parts must be learned before you 
can understand what is said about them, or write 
down what you find out yourself. This, then, will be 
your first business. If you begin at the outside of a 
flower (see the one shown, pulled apart, in Fig. 149), 
you come first upon the calyx. Next within the ca¬ 
lyx is the corolla. Inside of that are the stamens, and 
in the center of the flower you find the pistil. 
The Recep'tacle is the top of the peduncle, more 
or less swollen, from which the flower grows. 
The Ca'lyx is the outer circle of green flower- 
leaves. 
The Coroi/la is the inner circle of delicately-col¬ 
ored flower-leaves. 
The word Per'iantii is a name given to both cir¬ 
cles of flower-leaves when they are so nearly alike as 
not to be separable into calyx and corolla. See Fig 
155.
