In table II, we have given as a matter of information the elevation 

 of the upper limit of distribution, where this is exactly known. 

 Table III covers forms occurring in the larger Appalachian valleys, 

 as far north as North Carolina or the lower mountains in Georgia, 

 or both, to the coast, exclusive of the Maritime and Estuarine 

 Region. In table V appear species which considerably modify their 

 physiographic distribution elsewhere in the eastern United States, 

 and this fact is there, and in subsequent tables, indicated in paren- 

 theses. In table VIII, we have endeavored to express a peculiar 

 type of distribution : one covering the lower mountains and Piedmont 

 and, although absent from most or all of the Coastal Plain, extend- 

 ing south into southwestern Georgia or even into the adjacent 

 portion of northern Florida.
