Variety alabamensis has obovate leaf blades, much broader than var. serotina. The apices are usually obtuse, rounded, or rounded-emarginate, sometimes short-acute or short-acuminate. Branchlets and, sometimes, raceme axes are rusty-hairy; abaxial surfaces of leaf blades have scattered, rusty hairs. The trees are said to leaf out two weeks later than var. serotina and to hold their leaves much longer in the fall (C. L. Brown and L. K. Kirkman 1990).
