Staminate flowers campanulate, greenish yellow, about 3 mm. long, about 2 mm. in diameter at the orifice of the limb, minutely puberulent-papillate without, the stamens widely exserted. Pistillate flowers tubular to somewhat urceolate, about 2.5 mm. long and 1 mm. in diameter, the limb erect, the stigma and style widely exserted. Anthocarps borne upon greatly elongate pedicels, pentagonal-clavate, 7-9 mm. long, 3-4 mm. broad, green, coriaceous, the stipitate glands uniseriate upon the five angles, the sides minutely and densely puberulent.
