About : .

Members of the family Oleaceae are woody plants, mostly trees and shrubs; a few are lianas. Some of the shrubs are scandent, climbing by scrambling into other vegetation.

Leaves without stipules; simple or pinnately or ternately compound. The family is characterized by opposite leaves. Alternate or whorled arrangements are rarely observed, with some Jasminum species presenting a spiral configuration. The laminas are pinnately veined and can be serrate, dentate or entire at the margin. Domatia are observed in certain taxa. The leaves may be either deciduous or evergreen, with evergreen species predominating in warm temperate and tropical regions, and deciduous species predominating in colder regions.

The flowers are most often bisexual and actinomorphic, occurring in racemes or panicles, and often fragrant. The calyx and corolla, when present, are gamosepalous and gamopetalous, respectively, their lobes connate, at least at the base. The androecium has 2 stamens. These are inserted on the corolla tube and alternate with the corolla lobes. The stigmas are two-lobed. The gynoecium consists of a compound pistil with two carpels. The ovary is superior with two locules. The placentation is axile. Ovules usually 2 per locule; sometimes 4, rarely many. Nectary disk, when present, encircling the base of the ovary. The plants are most often hermaphrodite but sometimes polygamomonoecious.

The fruit can be a berry, drupe, capsule or samaras.
