Tree 7-14-30 m tall, trunk 15-60 cm in diam.; young branches brown to blackish; bark brown, tough, smooth, becoming whitish. Leaves 9-21 × 10-28 cm, with 5-7 entire leaflets, acuminate with a short mucro, gradually narrowed towards the base but not petiolulate; central leaflet 9-21 × 3-8 cm, lateral ones smaller; firmly membranaceous, in vivo brilliant green above and dull green below; glabrous, occasionally minutely pubescent on the midribs on the lower surface; petiole glabrous, dark brown, sulcate, 12-32 cm long; stipules pubescent, brown, ca. 5 mm long. Inflorescence ca. 50 cm long, with up to 12 lateral branches arising from the axils of consecutively reduced foliage leaves, with reddish or copper pubescence. Flowers 10-11 cm in diam. Sepals densely velvety without, minutely pubescent within; outer sepals 15-20 × ca. 8 mm. Petals obovate, apically emarginate for ca. 1.5 cm. Filaments 5-20 mm long, yellow or tinged with red; anthers 2-3 × 0.6-0.8 mm, curved. Ovary globose, densely tomentose, ca. 6 mm in diam. Capsule erect, one or two on a lateral branch, rarely more than 5-6 borne in a single infructescence; fruit obpyriform in outline, 7-10 × 2.5-4.5 cm, apex obtuse or rounded, base attenuate into a sterile part 2-3 cm long; stalk 2.0-2.5 cm × 3-4 mm; outer valve tomentose; placentae straight, not incurved, more or less contiguous with each other; inner valve separating from but completely contiguous with the outer valve and the placentae, thus forming an inflated box with a narrow central opening, enclosing the numerous seeds. Seeds 5-7 cm in diam., with a fringe of fine, dense, reddish hairs ca. 1 cm long.
