Vegetation of the southern edge of the Metamorphic 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 Alabama. 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:
