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

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 empkyed 
are explained.
