A list of plants that are common farther inland and conspicuous by their 

 absence or scarcity here would be a long one; but the following trees at least 

 deserve special mention in this connection: Pinus palustris (long-leaf pine, en- 

 tirely absent), P. Taeda and P. echinata (short-leaf pines), P. glabra and P. 

 clausa (spruce pines), Taxodium (cypresses), Chamaecyparis (juniper), Hicoria 

 (hickories), Salix (willows), Carpinus, Ostrya, Fagus (beech), nearly all oaks 

 except the live oaks, Morus (mulberry), Uhnus (elms). Magnolia glauca (bay), 

 Liriodendron (poplar), Crataegus (haws), Prunus (plums and cherries), Acer 

 (maples), TtVio (basswood or lin), Gordonia, Nyssa (black gums and tupelo 

 gums), Cornus florida (dogwood), Oxydendrum (sourwood), Diospyros (per- 

 simmon), and Fraxinus (ashes). Most of these prefer somewhat clayey soils, 

 which are entirely absent in the coast strip; but of course no one explanation 

 will fit all cases. It may be that some of them are averse to salt, lime and 

 phosphorus. 



None of the trees and shrubs seem to be specially ' characteristic of this 

 region except the Yucca and perhaps the Bumelia on dunes, Iva frutescens, Batis 

 and Borrichia in and around salt marshes, and Iva imbricata on upper beaches. 

 Many of the herbs, however, especially those of salt marshes and dune hollows, 

 are almost confined to this region ; and nearly all the herbs which grow here at 

 all are more abundant here than in the average of northern Florida (as indicated 

 by the + marks). 



About 94% of the trees (but not so many of the other plants) are evergreen 

 and 10% of the shrubs Ericaceae, and there are very few Leguminosae; all of 

 which indicates the prevalence of very poor soils. The salt marshes and dune 

 hollows, which contain few or no evergreens or Ericaceae, are evidently much 

 richer than the average, though. 



Economnc Features — As in the case of the West Florida coast 

 strip, there is practically no lumbering and no agriculture in this
