The leaves are alternate. From the original, opposite, couplets ( two line ) Beblätterung a leaf is always reduced and very small or entirely absent. The venation of the leaves is like a net, with many species except the midrib on each side still have two slightly above the base of the leaf branching, strong side ribs. The leaves are asymmetrical at the base. The leaf margin may be entire or toothed. The normal leaves have two stipules.
There are in the genus, and even within species, both monoecious as dioecious plants, the flowers are unisexual in the first case. The flowers are in axillary inflorescences zymösen. The perianth is four or fünfzipflig. In the male flowers, it is grown about half. The Perianthzipfel the female flowers are often unequal in length.
