 Ave have, Isl, the plants (d" the better drain(Ml creek 

 and river bottoms, and, 2ud, the moister and richer 

 norihern sloi)es of the ui)lands. Such locations are usu- 

 allv lu^avilv timlx^red mostlv with hard woods, but 

 occasionally mixed with loblolly pine (Pinit.s laeda) in 

 the lowlands, and with the short leaf pine {Finns 

 cchinata) in the uplands. These associations are rich 

 in the nundjer of species and include most of the more 

 northern types. The plants from the Gulf rej^ion are 

 to be sought on the dryer, more- sandy uplands, and in 

 the sandy bay heads and Sphagnum bogs. More or 

 less distinctly zero phytic associations occupy the greater 

 part of the upland area. Here we may distinguish. 

 1st, plants of the dry hardwood forests. These are usu- 

 alh' found on the south slopes of the red clay hills; 

 2nd, plants of mixed woods, including long or short leaf 

 pines and hard woods. This type of forest is the pre- 

 vailing one over a large part of the entire region; 3rd, 

 plants of the long leaf pine { Finns pahisiris) forests. 

 These are confined to the extreme southern border and 

 to a strip along the hills bordering the Tallapoosa river. 

 A large number of southern species are found in this long 

 leaf pine association; 4th, an extremely zerophytic asso- 

 ciation found on exposed granite outcrops. Occasionally 

 granite outcrops occur where they are somewhat moisted
