General Information

Shrubs or small trees, 2-4 m tall; young stems and leaves minutely rusty-papillose; older stems glabrous; bark grey, large white-lenticellate.
Sympodial units difoliate, geminate, strongly anisophyllous.
Leaves strongly anisomorphic, glabrous on both surfaces; major leaves elliptic, widest at the middle, 12.6-20.8 x 4.6-9.3 cm, with 5-10 pairs of main lateral veins, raised both above and beneath, the apex acuminate, the base acute to rounded, slightly winged on the petiole; petioles 0.9-2 cm long; minor leaves orbicular, 2-5 x 1.9-4.1 cm, the apex acute or obtuse, apiculate, the base broadly rounded or cordate; petioles 1-4 mm long.
Inflorescences opposite the leaves, simple, 0.3-1.5 cm long, 5-20-flowered, glabrous except for the rusty-papillose distal tips and very young buds; pedicel scars evenly spaced ca. 0.5 mm apart, beginning ca. 8 mm from the base of the inflorescence. Buds ovoid, rusty-papillose, the calyx lobes long-acuminate in bud, so that the bud appears pointed, completely enclosing the corolla. Pedicels at anthesis deflexed, 1-1.4 cm long, tapering from the calyx tube to a slender base ca. 0.5 mm in diam.
Flowers with the calyx tube 1-1.5 mm long, the lobes long-triangular to deltoid, 0.5-3 mm long, glabrous, the margins of the sinuses white and thickened; corolla white, ca. 1.8 cm in diam., lobed nearly to the base, the lobes reflexed at anthesis, the tips and backs of the lobes minutely papillose; anthers 3-4 x ca. 1.5 mm, poricidal at the tips, the pores tear-drop shaped; free portion of the filaments ca. 0.25 mm long, the filament tube ca. 0.5 mm long; ovary glabrous; style straight, slightly clavate, ca. 7 mm long; stigma a minutely papillose area on the tip of the club.
Fruit a globose, green berry, umbonate when immature, 1.1-1.8 cm in diam.; fruiting pedicels woody, erect, 1.8-2.3 cm, 0.75-1 mm in diam. at the base; calyx lobes erect and woody in fruit, 3-4 mm long.
