This list contains about 126 species (or nearly the same number as in 

 either of the two adjoining states), about 40 of which (12 gymnosperms and 28 

 angiosperms, together making up about 70% of the forest) are evergreen. The 

 only ones which seem to make up more than 1% of the forest (13 in number) 

 may be arranged in order of abundance as follows: Pinus palustris. P. Elliottii, 

 Taxodium imbricariitm, Pimis Taeda, Quercus Catesbaei, Magnolia glauca, 

 Pinus serotina, Liquidantbar, Nyssa biflora, Magnolia grandiflora, Pinus echinata, 

 Quercus cinerea, Q. falcata. 



The eight pines make up about 62% of the forests, or 60% of the total veg- 

 etation, and 21 arborescent oaks between 9 and \o%. (Alabama has the same 

 number of pines and of oaks, but in that state each makes up about 20% of the 

 forests, arrd not over 40% of the trees are evergreen.)
