Branchlets slender, tips densely pubescent, bearing 4 or 5 leaves, lower parts blackish-corticate and showing scars of fallen leaves. Leaves oblong-obovate, apex for ca 2.0 cm subcuspidate-acuminate, acute, base narrowly to broadly cuneate, very base maybe obtuse, membranaceous to thin-chartaceous, subsinuate-denticulate to subentire, laxly to rather densely set with longish soft subappressed whitish hairs on midrib, nerves and veins on both faces initially, finally more or less glabrescent, (8.0-)10.0-20.0(-28.0) cm long, 3.5-8.0(-11.0) cm broad, lateral nerves 8-10(-12) pairs, curved-ascending, prominent beneath, reticulation of veins and veinlets rather coarse, slightly raised beneath; petiole usually slender, densely hairy, 0.5-1.0(-1.5) cm long. Flowers scented, dioecious, the [male] in corymbose racemes reduced to 2 or 3 flowers, rarely solitary in the upper axils, on peduncle ca 1.0 cm long; pedicels yellowish-tomentulose, ca 1.0 cm long. Sepals 3, elliptic-suborbicular, appressed-hairy outside, almost glabrous inside, 1.0-1.5 cm diam. Petals 8 or 9, outer ones obovate-oblong, inner ones narrower, white, silky outside, less densely so except the base inside, 1.8-2.5(-3.0) cm long, 0.6-1.0(-1.5) cm broad. Stamens ca 40; filaments densely hairy, 2.0-3.0 mm long; anthers hairy, 5.0-6.0(-7.0) mm long. Flowers [female] solitary, axillary, on stoutish peduncle ca 1.0 cm long, articulate with the pedicel, ca 8.0 mm long. Sepals and petals as in [male]. Ovary subglobose, tomentulose, with 10 or 12 vertical short membranous crenate wings; styles ca 5, tomentose; stigmas short-lacerate. Fruit on peduncle 2.0-3.0 cm long, subglobular, all over yellow-green-subtomentose, (2.5-)3.0-4.0(-5.0, -7.0) cm diam, with 10 or 12 vertical membranous wings, these irregularly obtusely crisped-dentate, often more or less revolute, 3.0-8.0 (rarely -20.0) mm high, not covering each other; pericarp lignescent, not properly fibrose, 1.5-2.0 mm thick; seeds 15-30, polyhedric, white, pubescent, ca 10.0 mm long, with reddish aril.
