The following trees which are more or less common in near-by or similar 

 regions are notable for their scarcity or absence in this region: Cypress {Tax- 

 odiuiii distichum), cabbage palmetto, hickories, willow, ironwood (Carpiiius), 

 white oak, post oak (Quercus stellata), live oak, elms, hackberry, sycamore, 

 plums, redbud, lin (Tilia), Gordonia, tupelo gums (Nyssa uniflora and N. 

 Ogeche), sassafras, and ashes {Fraxinus). Most of these prefer soils richer 

 in potash or humus, or both, than those of the pine hills. On the other hand, 

 Chaniaecyparis,\ Crataegus lacrimata, and several of the herbs are in Florida 

 confined to ihis region or nearly so. Finns clausa, Illicium, Myrica inodora, 

 Conradina, Baptisia hirsuta and Fitclieria are not known in Georgia, and Nyssa 

 Ogeche, Querciis pumila, Baptisia hirsuta and Doellingeria reticulata are not 

 known in Alabama. 



About 75% of the vegetation in the western part and 77% in the eastern 

 is evergreen. (Although the difference between the two parts in this respect 

 is slight, it is reasonable to assume that it is correlated with the wetter sum- 

 mers eastward). About 15% of the shrubs are Ericaceae and 9.6% of the 

 herbs Leguminosae. The high percentage of evergreens and Ericaceae is 

 doubtless correlated with soils below the average in potassium content ; but 

 the percentage of Leguminosae is about the average. The latter seem to prefer 

 soils rich in calcium and potassium and poor in nitrogen or humus ; and here 

 the soils are somewhat deficient in all these constituents. Weeds are compara- 

 tively scarce. 



Economic Features — As in the case of the neighboring cypress 

 pond region (No. 2), the advantages of this kind of country may 

 be said to have been appreciated only recently. Grazing, lumbering 

 and turpentining have hitherto overshadowed all other industries, 

 (but agriculture is now rapidly forging to the front. As late as 1910

tThis tree, commonly called white cedar in the North and juniper in the 

 South, seems to be confined to swamps in which the water is exceptionally free 

 from mineral matter in solution or suspension. Both in Liberty and in Santa 

 Rosa County it grows along small creeks which are noted locally for their 

 clearness.
