PARTS OF THE FLOWER. 21 



a capsule, or little chest ; at a is a row of fine fibres, which 

 connect the valves or pieces of the capsule, and through which 

 the seeds are admitted. At b the capsule appears as if cut 

 transversely, shewing three cells or apartments, each contain- 

 ing two triangular seeds (b, b). 



These 7 parts constitute what are called the organs of Fruc- 

 tification,* viz. 



Calyx, the cup. Pericarp, containing the seed. 



Corolla, . blossom. Seed, rudiment of a new 



Stamens, organs within plant. 



the corolla. Receptacle, top of the stem. 

 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. 



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 

 name of the species is like the particular or Christian name ; for 

 example ; the Rose family contains many different species ; as 

 Rosa alba, the white rose, Rosa damascena, the damask rose, 

 &c. 



The specific or individual name in botany, is placed after 

 the family name, as Rosa alba, which is Rose white, instead of 

 white rose : this circumstance is probably owing to the names 

 being in Latin ; as in that language the adjective is generally 

 placed after the noun, instead of before it, as in English.
