ALTAMAHA GRIT REGION OF GEORGIA 343 



and any changes which may be taking place in the flora through 

 natural causes must be extremely slow. The changes due to 

 civilization have hitherto been much less marked than in most 

 other parts of temperate Eastern North America. 



The species indigenous to the region are in general rather re- 

 stricted in range, most of them being confined to the coastal 

 plain, as far as known, and about one-third of them to the pine- 

 barren portion of the coastal plain. A few range southward 

 into the tropics (and most of these are quite variable in habitat) , 

 but probably none cross the Atlantic Ocean or the Great Plains. 

 As a rule the most widely distributed species of vascular plants 

 occupy habitats which are likewise widely distributed in Eastern 

 North America, and belong to taxonomic groups relatively high 

 in the scale. 



As a whole the species composing this flora were mostly made 

 known to science during the nineteenth century. But the woody 

 plants have been known relatively much longer than the herbs, 

 and the trees somewhat longer than the shrubs.

 Grit region are described or mentioned (though in most of these no dis- 

 tinction is made between the region under consideration and those ad- 

 joining it). Arranged chronologically.

 Some if not most of the plants figured in this work are believed to have 

 come from the northeastern portion of the Altamaha Grit region.

 from Bulloch County. Several plants described as having been 

 collected near Louisville by James Jackson may have also come 

 from the Altamaha Grit region, as has been pointed out elsewhere.
