Flowers uniasexual, staminate and pistillate on separate plants; subtending bracts absent; perianth absent. Staminate flowers: stamens 2, in 1 series; anthers adaxially connate, dehiscing vertically; pollen linear. Pistillate flowers: pistils 2, distinct, not stipitate; ovules pendulous, orthotropous.
