Leaves crowded towards the end of the twigs, rounded or cuneate-obtuse at the apex, with cuneate, attenuate base and entire, revolute margin, glabrous (except in innovations and then puberulous), narrowly elliptic to obovate, 9-22 by 2½-7(-9) cm; nerves 11-15 pairs; petiole 2-4 cm.

Calyx with same indument, becoming glabrous towards the apex, 2-3 mm, the lobes c. 2 mm long. Corolla 8-10 mm. Stamens 50 to more than 100. Disk glabrous, annular, and then surrounding a lower, rarely shortly pilose receptacle, or low pulvinate, only surrounding the glabrous, 7-9 mm long style. Ovary with same indument as calyx, c. 2 mm high. Fruit ellipsoid, c. 10 by 7 mm in vivo; stone rather smooth, with few shallow lengthwise grooves, 8-10 by 4-5 mm (s.s. the whole fruit as big as the stone), 3-celled.
