FOR FINDING ANY PLANT, KNOWN OR UNKNOWN, 



IN THE FOLLOWING WORK. 



WHEN you have the English name of the Plant, or the Linnean name of the Genus to 

 which it belongs, it will only be necessary to refer to it in the alphabetical order of the 

 Dictionary , but if you should meet with a Flower or Plant to which you are an entire 

 stranger, you must first determine its Class and Order, according to the Rules already laid 

 down in the preceding Introduction ; (see page 6.) and having found them, inspect the Table 

 of Orders and Genera at the end of this Work, observing to which Genus of its Order your 

 Plant belongs. When this is done, you must refer to the description of the Genus by the alpha- 

 betical arrangement of the body of the Work ; and if that Genus contain only one Species, 

 that is the Plant in question ; but if it contain many Species, particular attention must be 

 paid to the circumstances which distinguish these Species; and when you have ascertained 

 to which Section of the Genus (if it be divided into Sections) your Plant belongs, and that 

 Section only includes one Species, which is often the 'case, you have found the Plant; but 

 if each Section includes several Species, very close attention must be paid to the charac- 

 teristics of each, as they are in general extremely minute, depending principally upon the 

 shape of the leaves and the roots.
