Alleghenian and Carolinian areas, Southern Connecticut, southern New York and 
New Jersey, west to Michigan, Missouri, and Tennessee. 
ALABAMA: Mountain region to Upper division Coast Pine belt. Wooded hills. 
Clay County, banks of Talladega Creek, 800 to 1,000 feet. Pike County, near Troy 
(Walnut Creek). Butler County, Mount Sterling, on limestone hills; notrare. The 
Alabama tree agrees perfectly with Pursh’s description; as observed in the State 
it is scarcely over medium size; the leaves smaller than in the type, generally 
acutely 3 lobed, with open rounded sinuses, pale to glaucous beneath. Although 
toward its northern limit closely connected with the type, in its southern range this 
torm is easily recognized as a well-marked variety. Further, judging by the phrase, 
“A, foliis breviter trilobis,” and by his giving Carolina for the home of the tree, there 
can be little doubt that Michaux in the description of his Acer barbatum had this 
Southern tree in mind. 
Type locality: ‘‘ Hab. in Carolina.”
