ALTAMAHA GRIT REGION OF GEORGIA

out). The plants listed below have been observed on the 

 Ogeechee River near Echo in Bulloch County (opposite Rocky 

 Ford), on the Oconee at two places near Mount Vernon, and on 

 the Ocmulgee at Upper Seven Bluffs in Wilcox County (see pages 

 17-18). A bluff on the Ocmulgee near Lumber City has about 

 the same flora, but is not included in this enumeration because 

 its geological structure is probably not exactly the same. 

 These bluffs are the only examples in the Altamaha Grit region 

 of the typical mesophytic forests which are so characteristic of 

 the older parts of the continent. Like the hammocks just dis- 

 cussed they are characterized by abundance of shade and humus ; 

 and their flora may be regarded as a step farther removed from 

 that of the pine-barrens than the hammock flora is, as will be 

 seen from the following list.
