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

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

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 employed 
are explained.
