Description : The Mountain Ash (Pyrus Aucuparia, Gaertn.) is not related to the true Ashes, but has derived its name from the similarity of the leaves.

In comparison to the true Ash, it is but a small tree, rarely more than 30 feet high. It belongs to the order Rosacece and is distinguished from its immediate relations the Pear, Crab Apple, White Beam and Wild Service Tree by its regularly pinnate, Ashlike leaves. It is generally distributed over the country in its wild state, but is also much cultivated as an ornamental tree.

All parts of the tree are astringent and may be used in tanning and dyeing black. When cut, the Mountain Ash yields poles and hoops for barrels. Both the bark and fruit have medicinal properties.

The fruit is rather globose, with teeth at the apex and two to three seeded cells. They are used medicinally in either the fresh or the dried state.
