alluded to. So also are the Cryptogamous or Flowerless Plants, as already 

 mentioned. To save room, when there is only one species, or only one common 

 species, to a genus, we do not proceed any farther with it than to the name of the 

 genus, both scientific and popular. 



Under the species the English or popular name is placed foremost, in small capi- 

 tals ; the scientific or Latin name at the end. The scientific names throughout are 

 printed in italic letters. 



Full instructions for using the Flora in studying plants are given in Chapter 

 IV. Section IV. ; at the close of which, the few abbreviations and signs empk-yed 

 are explained.
