ALTAMAHA GRIT REGION OF GEORGIA 305 



combined. In the region under consideration one can hardly 

 get out of sight of this species, except in the depths of some 

 swamp. It is equally abundant in all that part of Georgia 

 underlaid by Oligocene or later rocks (i. e., the "pine- 

 barrens"), except in Okefinokee Swamp, where it is absent, 

 and in the Upper Oligocene and maritime regions, where it 

 is infrequent. It ranges nearly throughout the coastal 

 plain (but is rare or wanting in most of the Eocene region), 

 and near the western boundary of the state it extends 

 inland to the mountains a little north of latitude 34 (see 

 Torreya 5: 55-60. 1905). 



Extreme southern Virginia to central Florida and eastern 

 Texas (see Torreya 3 : 122. 1903 ; Bray, Bull. Bureau Fores- 

 try, U. S. Dept. Agr. 47: 21-23, 53- pi- 7 > ^- *^ I - 1904). 

 Confined to the coastal plain except in Georgia and Ala- 

 bama as above noted. This is perhaps the most abundant 

 and important tree in North America at the present time.

 the following species of Pinus see Mohr's Timber Pines of

Moist pine-barrens, branch-swamps, cypress ponds, etc. 

 (never in mud or permanent water) ; common throughout, 

 probably on every square mile of our territory, but far 

 less abundant than the preceding. In Georgia its inland 

 limit coincides with that of the pine-barrens (i.e., with the 

 boundary between the Eocene and Oligocene regions) . From 

 there to the coast it can be found almost everywhere, in- 

 cluding Okefinokee Swamp and some if not most of the sea 

 islands, where P. palustris is absent.
