of vines, shrubs, and small trees, in about
100 genera. Celastrus , Euonymus and
Maytenus widespread in temperate climates.
Celastraceae leaves are simple and alternate or opposite; stipules are small and caducous or absent. The flowers are bisexual or sometimes functionally unisexual, actinomorphic, and are small and often greenish. The calyx comprises 4 or 5 usually basally connate sepals. The corolla is rarely absent or more commonly consists of 4 or 5 distinct petals. The androecium consists of 4 or 5 or rarely 10 distinct stamens that alternate with the petals. The gynoecium is a single compound pistil of 2-5 carpels, a single short style, and a superior or rarely half inferior ovary with 2-5 locules, each containing usually 2 axile ovules. An annular nectary disk surrounds and is usually adnate to the ovary. The fruit is a capsule, berry, samara, or drupe.
