Flowers unisexual (dioecious) hypogynous, pedicels articulate, up to 7-10 mm long, bracts minute. Male flowers: pale yellow, about 8-12 mm across in two compact fascicles with common strigosely tomentose peduncle, about 7-15 mm long and strigosely tomentose pedicels, about 7-10 mm long, sepals 4-5, imbricate, subequal, ovate-orbicular, base cuneate, concave, margins ciliate, apex obtuse, brown tomentose, about 4 mm long, petals 4-5, ovate-orbicular to broadly ovate, ovate-orbicular, base cuneate, concave, margins ciliate, apex obtuse.

Female flowers: 2-5 in compact fascicles, rarely solitary, because of abortion, peduncle about 5 mm long, usually from the older nodes, sepals and petals similar to male flowers but bigger, staminodes 10-16, linear-oblong, appressed to ovary apex obtuse, ovary superior, ovoid, obscurely 6-7 ribbed, densely brown tomentose, carpels 4, connate, unilocular, stigma 4, usually equaling the number of placentae, recurved, bifid deeply.
