Petiole 6-10 mm, glabrous; leaf blade drying thinly papery, elliptic to ovate, 9-14 × 5-8.5 cm, both surfaces sparsely puberulent to glabrous, base obtuse to rounded, apex acuminate; secondary veins 6-8 pairs, without domatia; stipules often persistent, broadly triangular, ovate, or orbicular, 3-10 mm, glabrous, rounded to truncate or sometimes shallowly emarginate.
