PLATE XXVI
THE ROWAN OR MOUNTAIN ASH
The Rowan tree is closely related to the roses, and is a cousin of the Hawthorn, the Apple, and the Pear. It is not related in any way to the Ash, but the leaves have some resemblance, because, like the Ash tree leaves, they are made up of many pairs of small leaflets growing opposite each other on each side of a centre stalk, and with an odd leaflet at the end. But the leaflets of the Ash tree have each a stalk; those in the Rowan have none, and in the Ash tree each large feathery leaf is planted exactly opposite its neighbour, while in the Rowan the leaves grow alternately. The name Mountain Ash is a mistake.
