*Some botanists include the Oleaceae in the order Lamiales.

Ash is the name of three very distinct group of trees. It generally refers to trees of the Genus Fraxinus, but in North America, "ash" may also refer to species of Sorbus, more accurately known as Rowans and Whitebeams. In Australia, "mountain ash" refers to a type of eucalyptus, Eucalyptus regnans, one of the tallest trees in the world.

The Genus Fraxinus is in the olive family (Family Oleaceae). Ashes are usually medium to large trees. Most have pinnately-compound, opposite leaves. Seeds are borne in keys, a type of fruit known as a samara.

The White ash is a particularly important timber tree in eastern North America, and is the source of wood for quality wooden baseball bats. The Green ash is widely planted as a street tree in the United States. The inner bark of the Blue ash has been used as a source for a blue dye.
