Inflorescences sparsely to densely pilose; flowers 5-parted; calyx orange; corolla yellow; staminate inflorescences solitary, pendent; peduncles to 15 cm long; staminate flowers sessile, in subglobose clusters; floral rachis 1-2 cm long; calyx ovoid at base, densely vinous, the lobes almost filiform, to 4 cm long; corolla fleshy, acute at apex, only slightly exceeding anthers, conspicuously papillose-puberulent, to 15 (24) mm. long, the tube constricted above anthers; anthers 2, included, dorsifixed, subsessile, narrowly ovate, 5-6 mm long; pistillate flowers pedicellate, several per axil, on usually leafless nodes at the stem apex; pedicel and ovary together 1.5-2 cm long; pedicels 4-5 cm long in fruit; inner surfaces of calyx and corolla glabrous, otherwise much like staminate flowers. Fruits cylindrical, 4-6 cm long and 2-2.5 cm broad, green at maturity with the old flowers persisting; seeds many, depressed-ellipsoid, 6-9 mm. long and 3-5 mm broad, white. Croat 5674, 9408.
