Long Leaf Pine Region.—This division constitutes the 
whole of the state south of the Jackson prairies and east of the 
Loess region, except a low flat coastal stretch a few feet above 
sea level, and extending from five to fifteen miles inland from 
the beach. The soil here is sandy, and as just stated, the floris- 
tic characteristics are noticed in the eastern half cf the state 
extending as far north as Meridian, thus lapping over that end 
of the Jackson prairie region. Since the red sandy formation 
that furnishes the soil of the leng-leaf pine section extends 
north of Meridian, the flora of the region has followed the soil 
northward. 
As mentioned above, this is a reddish-brown sandy loam, 
and is on the whole a more sterile soil than any of those already 
considered. It is generally poor in all the elements cf plant 
food, and when above drainage is very dry. In the southern 
parts, however, low swales and flats between ridges are poorly 
drained, with wet and acid soil. The water--logged condition 
of the soil induces an acidity simulating the condition of a nor- 
thern bog, with the result that these places support a flora 
very suggestive of bog flora. 
The upland forests of this region are almost pure lon- 
leaf pine (Pinus australis), with a very sparse sprinkling of 
other trees, though near the northern boundary there is a large 
admixture of short leaf yellow pine, and on the western border 
a considerable hardwood growth invades from the loess forests. 
Along stream valleys the pines are replaced by hardwoods of
