Abstract

Shrubs or trees, the 600 species included in the olive family all have opposite leaves. Flowers are regular, although they may be perfect or unisexual. Calyx when present is four-merous. Corolla lobes also number four, although the corolla may be absent or the petals distinct. In sympetalous species the stamens, 2–4, are borne on the tube. The ovary is superior, divided into a pair of locules. Fruits are of several types. A prized oil is produced by the olive (Olea europaea). Some of our common ornamental shrubs are included in this family, such as lilac. Photos supplied by Sean Blaney, Ross Hall, Martin Thomas, Marian Munro and Beth Cameron.
