of it a flower leaf ; but in the language of botany, the pieces 
which you call flower leaves, are the Petals, and all the petals 
together are called the Corolla. 
By examining the lily you will observe within the corolla six 
thread-like organs ; these are called Stamens. Each stamen is 
composed of two parts, one long and slender, called the Fila- 
ment ; the other part called the Anther , is a kind of knob, like 
a little box, which when the flower comes to maturity, opens, 
and throws out a coloured dust, called the Pollen. 
The central organ is called the Pistil ; this consists of three 
parts, the top, which is called the Stigma, the slender fila- 
ment which bears the stigma is called the Style, and the base 
is called the Germ. 
In many flowers the corolla is surrounded by a kind of cup 
called the Calyx, this is wanting in the Lily, but exists in the 
Pink. 
The Receptacle, is the end of the stem where all the other 
parts of the flower are inserted. 
The Germ, as it advances to maturity is termed the Pericarp, 
and in this is contained the seed. 
These 7 parts constitute what are called the organs of Fruc- 
tification,* viz. 
Calyx , the cup. 
Corolla, blossom. 
Stamens, organs within 
the corolla. 
Pistil, central organ. 
We have now examined each part of a flower ; this is one 
kind of analysis, or separation, but there is another kind of 
analysis with which you are now to be made acquainted, viz. 
that which we employ in finding out the Botanical name of a 
plant. 
Pericarp, containing the seed. 
Seed, rudiment of a new 
plant. 
Receptacle, top of the stem. 
DIVISION OF PLANTS INTO CLASSES, &C. 
According to the system now most used by botanists, plants 
are divided into twenty one classes. Each class is divided into 
Orders, the Orders into Genera, f and the Genera into Species. 
The name of the Genus is like a family name or surname ; the 
* From fructus fruit and facto to make, signifying that those parts serve 
to the maturing of the fruit. 
t Plural of Genus, a family or tribe. 
Petals — Corolla — Stamens — Parts of the stamens — Pistil — parts of the 
pistil — Calyx — Receptacle — Pericarp — Seed — Number of Classes — Genus 
— Species.
