Acer elegantulum is characterized by its velutinous ovary and nearly glabrous abaxial veins and petiole. Acer pubinerve differs by its velutinous abaxial veins and petiole. These two taxa are difficult to distinguish and possibly can be combined. They differ from A. sinense by their smaller papery leaves, slender petioles, smaller samaras, and velutinous ovary.
