LIXNEAN SYSTEM OF VEGETABLES. 



All Vegetables are divided into twenty-two* classes. 

 These classes are divided into orders. Orders are divided 

 into GEifEHA. Genera are divided into species. Species are 

 frequently changed into varieties. Varieties, however, are 

 more properly within the province of the Gardener, than of 

 the Botanist ; at least the method of procuring varieties. 



When a Botanist sees a plant, which he never saw before, 

 and wishes to know its name and uses ; he proceeds as fol- 

 lows. 



1. He takes the unkno^^'n flower in his hand (no unknown 

 plant can be ascertained without the flower) and compares its 

 parts with the description of each class, until he finds the 

 class to which it belongs. 



2. He then goes to the orders of that class and finds its 

 order in the same way. 



3. Next he goes to the genera of that order, and reads 

 their descriptions, until he finds the genus to which it be- 

 longs. 



4. At last looks over the species of that genus, until he 

 finds the exact description of his plant. 



5. Thus he finds the Apple to be Class 12, Order 5, Ge- 

 Krs Pyrus, Species Malus. 



* Linneus divided them into 24 classes. But farther dis- 

 coveries, since his death, have proved the classes Polyadel- 

 phia and Polygamia to be too uncertain and variable to be 

 any longer retained. Persoon, therefore, and other eminent 

 Botanists, have rejected them. See these classes in the Dic- 

 tionary.
