Leaves: Leaves simple. Alternate. Blades broadly elliptic to obovate, blades 15–23 cm long, 7–11 cm wide. Apex acuminate. Base obtuse. Upper surfaces green, glabrous to sparsely muricate; lower surfaces pale green, glabrous, pubescent, muricate, or aculeate. Margins callose–dentate. Petioles 4–7 cm long, glabrous, muricate, or aculeate. Stipules absent.

Ovary inferior, 2-celled; ovule placentation axile; stigma 2-lobed, wet or dry, appressed and nonreceptive as the style grows through the anther tube, pushing out the pollen, after which the stigmas spread apart and become receptive.
