Vines 1.5-3[-15] m, woody. Twigs pale red or pale tan-colored when dry, stout, terete, lenticellate, pubescent with stellate and simple brownish trichomes, eventually glabrescent; internode length unequal, to 5 cm or longer. Petiole 1-2(-4?) cm, terete; leaf blade elliptic, oblong, or oblong-lanceolate, broadest at middle or slightly apically, (11-)14-17 × (2.5-)3-5.5[-9] cm, both surfaces sparsely pubescent with stellate trichomes, eventually glabrous except along veins, secondary veins 6-8 on each side of midvein, reticulate veins obvious, base cuneate to narrowly cuneate, apex nearly rounded to acuminate and with a 5-12-mm tip. Inflorescences terminal, sparsely branched panicles, (8-)12-35 cm, at first erect then drooping; axis shortly pubescent to shortly tomentose; bracts linear, 3-6 mm, trichomes like those on axis. Pedicel 3-6 mm, slender. Receptacle (torus) dish-shaped, ca. 1 mm in diam. Sepals (5 or)6, pale yellow, ovate-lanceolate, 4-6 × 1.5-2.5 mm, reflexed, both surfaces densely tomentose, apex acute to obtuse. Androgynophore ca. 2 mm, glabrous; stamens (20-)26-30[-40]; filaments 3-5 mm, glabrous; anthers 0.5-0.7 mm. Gynophore 2-2.5 mm, with dense tan pubescence; ovary ellipsoid, 1.7-2.5 mm, glabrous or basally sometimes with trichomes; styles 3(or 4), apex recurved; stigma obscurely 3-lobed. Fruit orange when mature, ellipsoid, ca. 4 × 3 cm, surface with thin yellow verrucose flecks; endocarp thin, woody; fruiting pedicel plus gynophore 6-8 mm, ca. 5 mm in diam. Seed ellipsoid, 1.2-1.5 cm. Fl. Apr-May, fr. Aug-Oct.
