rocks. The original timber gro\Ytli varied from almost 

 pure long leaf pine forests at the southern border and 

 along the blufPs of the Tallapoosa, to pure hardwood 

 forests on the richer areas, especially to the northward. 

 The greater part of the area was, however, a mixed for- 

 est of hardwoods and long or short leaf pines. The re- 

 gion is divided into nearly equal parts by the Tallapoosa 

 river, the portion to the south and east being the high, 

 broad ridge that forms the divide between this stream 

 and the Chattahoochee. The northwestern portion 

 fonning the divide l)etween the Tallapoosa and the Coosa 

 i;s more rugged and broken, and in the Talladega Moun- 

 tains reaches the highest elevations to be found in the 

 State (2,300 feet). This is one of the most interesting 

 parts of the State, and deserves much more extended 

 study. It was visited only once by Dr. Mohr and once 

 by the writer. 



This metomorphic region is of special interest botani- 

 cally since it constitutes the southernmost extension of 

 the Carolina Life Zone. Many of the characteristic 

 plants of the Appalachian system find here their most 

 southerly stations while mingling witli these northern 

 representatives are many plants that have pushed up 

 fi'om the Gulf region. This mingling of the two floras 

 ac€ounts for the large number of species found. Of the 

 1146 species and varieties ennumerated in the following 

 list, 94 are new to the State, and are not included in Dr. 

 Mohr's work. These are indicated by an asterisk (*). 

 There are 76 others tliat were previously known in Ala- 

 bama only from the northern part of the State. These 

 represent an extension of the known range in the State 

 to the southward, and are marked by a dagger (f). 

 There are also 167 species that represent a northerly ex- 

 tension of the known range Avithin the State. These are 

 indicated by a double dagger ( |) . The larger number
