Oleaceae
The Oleaceae are trees or shrubs comprising about 30 genera and 600 species. The leaves are opposite and simple or pinnately compound; stipules are absent. The flowers are actinomorphic and bisexual or rarely unisexual. The calyx is typically small and synsepalous, and most commonly 4-lobed but sometimes has more lobes or rarely is absent. The corolla is actinomorphic, 4-merous or sometimes up to 12-merous, and is nearly always sympetalous, though sometimes very deeply lobed. The androecium usually consists of two stamens born on the corolla tube or perigynous zone, alternate with the lobes. The gynoecium consists of a single compound pistil of 2 carpels, a single or no style, and a superior ovary with 2 locules, each with usually 2 axile ovules. A nectary disk is sometimes present around the base of the ovary. The fruit is variable. |
