proximal blade margins entire or serrate;

juvenile blade glabrous, pilose, or puberulent abaxially.

stipules absent or rudimentary;

petiole shallowly to deeply grooved adaxially, 3–13 mm, with pairs of spherical glands distally or throughout, glabrous adaxially;

proximal blade margins serrulate or entire;

juvenile blade reddish or yellowish green, glabrous abaxially.
