The alternate, long-stemmed leaves are twofold. The leaf stalk is up to 12.5 inches long. The slightly leathery, glabrous and entire, short-stalked leaflets are about 6-15 centimeters long and pointed to pointed. They are glandular-dotted and ovate to obovate. The rounded to blunt base is often uneven. The small stipules are sloping.
