A compact shrub to 1 metre in height, though often much less. The small, sparse leaves are arranged in alternating columns on opposite sides of the stem. Leaves are usually oblong in shape, hairy, and noticeably curved at the margins and tips. Flowers are small and creamy-yellow. Male and female flowers are held on separate plants. Male plants produce larger flower clusters. Flowers are followed by green fruits which contain irregularly shaped brown-black or purple-black seeds.
