deciduous;

petiole multicellular eglandular-hairy and unicellular-hairy;

blade ovate to obovate, 2.9–8.5 × 1.2–3.5 cm, thin, membranous to chartaceous, margins entire, plane, ciliate, eglandular-hairy, apex acute to obtuse, often mucronate, abaxial surface glabrous or densely unicellular-hairy and/or eglandular-hairy, adaxial surface scattered eglandular-hairy, otherwise sparsely unicellular-hairy, glabrate in age.
