Sorbus domestica (Service Tree, or sometimes True Service Tree to distinguish it from the Wild Service Tree; syn. Cormus domestica (L.) Spach) is a species of Sorbus native to western, central and southern Europe, northwest Africa (Atlas Mountains), and southwest Asia (east to the Caucasus).[1][2][3][4][5]

It is a deciduous tree growing to 15–20 m (rarely to 30 m) tall with a trunk up to 1 m diameter, though can also be a shrub 2–3 m tall on exposed sites. The bark is brown, smooth on young trees, becoming fissured and flaky on old trees. The winter buds are green, with a sticky resinous coating. The leaves are 15–25 cm long, pinnate with 13-21 leaflets 3–6 cm long and 1 cm broad, with a bluntly acute apex, and a serrated margin on the outer half or two thirds of the leaflet. The flowers are 13–18 mm diameter, with five white petals and 20 creamy-white stamens; they are produced in corymbs 10–14 cm diameter in late spring, and are hermaphrodite and insect pollinated. The fruit is a pome 2–3 cm long, greenish-brown, often tinged red on the side exposed to sunlight; it can be either apple-shaped (f. pomifera (Hayne) Rehder) or pear-shaped (f. pyrifera (Hayne) Rehder).[1][2][3][4]

It is a long-lived tree, with ages of 300–400 years estimated for some in Britain.[4]

Standard Cyclopedia of Horticulture

Sorbus domestica, Linn. (Pyrus Sorbus, Gaertn. P. domestica. Smith. Cormus domestica, Spach). Service Tree. Fig. 3650. Round-headed tree, 30-60 ft. high: winter buds glutinous: petioles tomentose; lfts. 11-17, obovate-oblong to oblong, sharply and rather coarsely serrate, with acuminate teeth, usually entire near the base, green and glabrous above, floccose-tomentose beneath, at least when young, 1-2 1/2 in. long: fls. white, 1/2 in. across, in broadly pyramidal rather loose, tomentose corymbs: fr. 1/2 – 1 1/4 in. across, usually yellowish, with red or orange cheek, apple-shaped in var. maliformis, Lodd., pear-shaped in var. pyriformis, Lodd. May. S. Eu., N. Afr., and W. Asia.—This species is often confounded with the European mountain-ash, from which it is almost indistinguishable without frs. or fls., except by the glutinous winter buds. CH
