The Flower. gI 
normal cherry flower, is called the calyx. In some plants, 
as the flax, the calyx is composed of several distinct, more 
or less leaf-like 
parts, each of which 
is called a sepal (se’- 
pal). In the cherry 
blossom, the sepals 
are united nearly to 
the top. The calyx 
is usually, but by no

corolla; S.stamens. (After Gimp). In the tulip and 
many other flowers of this class, it is generally colored like 
the corolla. In the apple and pear, the calyx becomes a 
part of the fruit, and its points are visible in the basin of 
the fruit, i. e., the depression opposite to the stem. 
143. The Corolla (co-rol’-la). The more spreading 
part of the cherry blossom, normally colored white (Cor., Fig. 
43) constitutes the corol/a. In the cherry, the corolla consists 
of five distinct parts, only three of which appear in the figure, 
called petals (pet’-als). In many plants, as the pumpkin 
and morning glory, the petals are united into one. In other 
plants they are united part way to the top. The corolla is 
usually, but not always, some other color than green. 
144, The Stamens (sta’-mens). Inside the corolla, is 
a group of slender organs (S.8., Fig. 43) called stamens. Each 
stamen consists of three parts, viz., the long and slender por- 
tion, connected with the calyx below, called the filament 
(fil’-a-ment); the swollen part at the top, called the anther 
{an’-ther); and the yellow dust, found within the anther, 
called the pollen (pol’-len). Each grain of pollen is a single
