An evergreen shrub of the Ilex family, with stiff leaves with sharp teeth and red berries, which are used as Christmas decorations. It can reach a height of 6 m and branch out well into a pyramidal shape. Young branches are hairless. The leaves are alternate on short stalks, oblong-ovate, 4-8 cm long, with wavy edges and several sharp triangular teeth, but the older the tree, the fewer the number of teeth. Male and female flowers are on separate plants and bloom in clusters in the axils of the previous year's branches in May and June. The flowers are small and white, with 4-5 sepals and petals, stamens in male flowers, and pistils and degenerated stamens in female flowers.
