The Sorb or Service tree (Pyrus Sorbus) is an interesting species of Pyrus, a native of Europe, which is sometimes seen in our gardens, and deserves a place for its handsome foliage and its clusters of fruit; which somewhat resemble those of the Mountain ash, and are often eaten when in a state of incipient decay. The leaves are coarser than those of the Mountain ash, and the tree is larger, often attaining the height of 50 or 60 feet in its native soil.
