The leaves are oblong-lanceolate, 5-10 cm long, with sawtooth edges, whitish-green undersides, and have a scent of corn and vanilla. The leaves are odd-pinnate and compound, with around 10 pairs of leaflets. Dioecious. In summer, the panicle grows at the top, with numerous, small, pale green flowers. There are five sepals and five petals. Male flowers have five stamens, and female flowers have one pistil made up of three carpels.
