Shrubs to small trees, 2-8 m tall; young stems and leaves glabrous to minutely puberulent with erect uniseriate trichomes ca. 0.1 mm long, these golden in dry specimens; older stems glabrate, occasionally with some scattered uniseriate trichomes; bark of older stems reddish-brown, later greyish.
Sympodial units usually difoliate, geminate.
Leaves very large, obovate, widest distal to the middle, usually in the distal third, glabrous above, occasionally with minute uniseriate trichomes along the veins beneath, this condition extremely variable; major leaves 15-40 x 9-20 cm, with 9-11 pairs of main lateral veins, these raised above, prominent and golden beneath, the apex acute, the base variable, from sessile and slightly cordate to acute; petioles 0-1 cm long, often broadly winged with the decurrent leaf base; minor leaves differing from the major ones in shape and size, orbicular to obovate, 2.5-13 x 1.5-9 cm, the apex acute, the base rounded to acute; petioles ca. 5 mm long.
Inflorescences terminal and overtopping the leaves at the shoot tips, later lateral and opposite the leaves, complex and many times furcate, 6-25 cm long, 20-100-flowered, sparsely to densely puberulent with erect uniseriate trichomes like those of the young stems and leaves, the trichomes 0.1-0.3 mm long, golden in dry specimens; pedicel scars irregularly spaced 1-5 mm apart, corky and slightly raised from the inflorescence axis. Buds globose and completely enclosed in the calyx when quite young, later the corolla exserted and the buds long-ellipsoid, the corolla ca. 2 times longer than the calyx tube. Pedicels at anthesis deflexed, white and fleshy, 0.6-1.1 cm long, tapering from the abrupt narrowing below the calyx tube to a slender base ca. 0.5 mm in diam.
Flowers with the calyx tube thick and woody, fleshy, white or greenish-white in live plants, broadly cup-shaped, 2.5-3.5 mm long, the lobes broadly deltoid, occasionally apiculate, the margins thickened and whitish in dry material, glabrous or minutely puberulent with erect uniseriate trichomes ca. 0.1 mm long; corolla white and fleshy, 1.5-2.5 cm in diam., lobed 2/3 of the way to the base, the lobes planar at anthesis, the tips and margins of the lobes densely papillose with occasional uniseriate trichomes; anthers 3.5-4 x 1-1.5 mm, the terminal 0.5 mm thickened and paler, poricidal at the tips, the pores tear-drop shaped; free portion of the filaments 0-0.5 mm long, the filament tube 0.5-1 mm long; ovary glabrous or pubescent with minute golden uniseriate trichomes ca. 0.1 mm long; style in long-styled flowers 0.8-1 cm long, in short-styled flowers ca. 1 mm long, straight; stigma capitate, minutely papillose.
Fruit a globose, green berry, 1-1.5 cm in diam., in dry specimens woody and hard; fruiting pedicels erect and woody, 1-1.7 cm long, occasionally deflexed due to the weight of the fruits and the size of the inflorescence, 1.5-2 mm in diam. at the base, thicker at the apex, ca. 3 mm in diam.; calyx lobes slightly accrescent and woody in fruit.
Seeds pale tan, ovoid-reniform, 2.5-4 x 2-3 mm, the surfaces minutely pitted.
