Discussion

Species 10 (1 in the flora).

Species of Aucuba are commonly planted in temperate gardens because of their evergreen habit, glossy leaves, and brightly colored drupes. Inflorescences may sometimes appear axillary, but actually are terminal in association with branches arising from the axils of the subtending pair of leaves.
