PREFACE. 
Tue object of this work is to present to students and to prac- 
tical botanists a systematic arrangement of the Phoenogamous and : 
higher Cryptogamous Plants of the Southern portion of the United 
States. 
My original design did not contemplate so wide a ficld; but was 
limited to an enumeration of the plants of the Carolinas, Georgia, 
and Florida, — to which, chiefly, my attention has -been directed 
during the last thirty years. But, influenced by the solicitations 
of friends, and by the apparent need of a more general work, I 
have extended my plan, so as to embrace all the States south of 
Virginia and Kentucky, and east of the Mississippi River. 
The plan of the work is nearly the same as that adopted by 
Proressor Gray, in his excellent Manual of the Botany of the 
Northern United States. 
For the benefit of those students who may not have a more per- 
fect treatise at hand, I have prefixed to the Flora a very concise 
Sketch of the Elements of Botany, and also a Glossary of Botan- 
ical Terms. But I would earnestly recommend, to those who may | 
use this work, the admirable Botanical Series* of the author
