The leaflets are 1.5 to 3 centimeters long, obovate-wedge-shaped and with a bluntly serrate to serrated edge (15 to 25 sections). The underside of the leaf is usually hairy when pressed against the veins, while the upper side is sparsely hairy or hairless. The basal stipules are membranous and have lanceolate auricles . Higher stipules are ovate and deciduous.
