Vegetation of tJie .'southern edge of the Metamarphic hills. — An 

 extensive collection of the vascular plants, made in the vicinity of 

 Auburn, Lee County (850 to 900 feet altitude), near the border line of 

 the Louisianian area, was kindly contributed by the Biological Survey 

 of Alabaiiia. From a district investigated botanically but slightly 

 before, it proved of particular interest, showing the intermingling of 

 Alleghenian types with many from the Coast plain and a number of 

 local species sparsely scattered through the Carolinian and Louisianian 

 areas, of which the following are remarkable examples: 



Dryopterisforidana} Coleosantltus {BrickcUia) cordifolius.
