The adoption of the arrangement of Plants according 

 to the Natural method, is continually increasing ; and under 

 the very prevalent impression that it will, ere long, be brought 

 into general use, the Author has been induced to compile 

 the present Work according to the Natural System ; at the same 

 time, there is prefixed to each genus, the Linneau Class and 

 Order to which it belongs ; and it will be seen that, not unfre- 

 quently, Plants of one genus will belong to several of the Lin- 

 nean Classes and Orders. Natural Orders are also of more real 

 service to the cultivator, as it brings together the groups of 

 Plants that are nearest related, and which very generally re- 

 quire nearly the same sort of management ; and Plants that are 

 diflScult to propagate, may very frequently be readily in- 

 creased, by grafting or inarching on some other belonging to 

 the same Natural Order, but will seldom or never do any good 

 on Plants that are not so related. 



Besides the adopted names of the Plants, and references to 

 the Books where they are figured or described, numerous of 

 the most essential Synonyms are given, so that any Plant is 

 known as well by its different names, as by the adopted one ; 

 the want of this has of late been much complained of by 

 Cultivators.
