The leaf base is broadly wedge-shaped or more or less rounded, the tip is twisted and pointed. The upper side of the leaf is green, glabrous or hairy near the base along the midrib, the underside is pale or slightly glaucous, initially shaggy hairy and later balding.[1]

The inflorescence axis is finely hairy. The bracts are broadly elongated, about 2.5 millimeters long, on the underside and on the leaf margin loosely finely haired or almost hairless. The tip of the leaf is blunt-rounded or wavy-serrated. Female flowers have an adaxial lying nectar gland . The ovary is ovoid-conical, glabrous, sitting or near sitting.
