Cormus domestica, commonly known as service tree[2] or sorb tree, is a species of tree native to western, central and southern Europe, northwest Africa (Atlas Mountains), and southwest Asia (east to the Caucasus).[3][4][5][6][7] It may be called true service tree,[5] to distinguish it from wild service tree. It is the only species in the monotypic genus Cormus.
It is a deciduous tree growing to 15–20 m (49–66 ft) (rarely to 30 m or 98 ft) tall with a trunk up to 1 m (3 ft 3 in) diameter, though it can also be a shrub 2–3 m (6.6–9.8 ft) 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 (5.9–9.8 in) long, pinnate with 13–21 leaflets 3–6 cm (1.2–2.4 in) long and 1 cm (0.39 in) 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 (0.51–0.71 in) diameter, with five white petals and 20 creamy-white stamens; they are produced in corymbs 10–14 cm (3.9–5.5 in) diameter in late spring, and are hermaphrodite and insect pollinated. The fruit is a pome 2–3 cm (0.79–1.18 in) 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).[3][4][5][6]
