have thought it advisable to dispose the plants here 

 enumerated in their natural orders, according to that 

 system.* 



In investigating the plants around New Bern I was 

 much assisted by my friends Dr. H. Loomis, (now of 

 Macon, Geo.) and George Wilson, Esq. oi'Nevv Bern, 

 to whom I take this occasion of tendering my ac- 

 knowledgments. 



Many of the more difficult plants of this catalogue 

 have passed under the inspection of Prof. Torrey. 



A few of the species here enumerated do not be- 

 long to the immediate vicinity of New Bern. The 

 principal of these are Ilex vomitoria and Uniola pa- 

 niculata on the sea-coast below, and Petalostemon 

 corymbos'um, MacbrideajwJc/mz, Vernonia oligophylla 

 Rhuspumila, and Robinia hispida in the county of 

 Lenoir, above. 



The line of division between northern and 

 southern plants, proposed in Eaton's Manual of 

 Botany, (6th edition) appears to me to be carried too 

 far north. I find that several interesting Southern 

 plants terminate their northern range in the district 

 lying between the Cape Fear and Neuse Rivers, in 

 North Carolina. These are Chamserops Palmetto, 



* This system may now be studied with much advantage in the 

 second edition of Professor Lindley's " Natural System of Botany," 

 London, 18.37.
