Discussion
Carpinus caroliniana subsp. caroliniana is characteristic of the southern Atlantic and Gulf of Mexico coastal plains and also extends northward in the Mississippi Embayment. It differs from C. caroliniana subsp. virginiana in its smaller, more ovate, more acute-tipped leaves that have finer secondary teeth and lack conspicuous dark glands abaxially.
