PREFACE. 



When the first edition of this work was issued, some 

 portions of the countiy embraced within the limits assigned 

 to it were imperfectly investigated or wholly unexplored. 

 But the discoveries in Southern botany made during the 

 last few years by Feay, Garber, Cnrtiss, and others, of 

 tropical forms on the peninsula and keys of Florida, by 

 Dr. Gattinger of Northern forms which extend into Ten- 

 nessee and the mountains of North Carolina, and by cor- 

 respondents from other States, have become, so numerous 

 that a new edition of the Southern Flora is required to 

 embrace them. 



In this edition I have concluded to incorporate these 

 additions in the form of a Supplement to the first edition, 

 avoiding any material alterations in it. 



And now, since the different sections of all the States 

 which are included in the limits embraced by this work 

 have been pretty thoroughly explored, and future acqui- 

 sitions will, probably, be comparatively few in number, 

 the time seems to have arrived when the promise pro- 

 visionally made in the Preface to the first edition may be * 

 at least partially fulfilled.
