'''''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]]).<ref name=rotach>Rotach, P.

Sorbus domestica L. - comparative morphology and habitats. ''BSBI News'' 73.</ref> 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 [[leaf|leaves]] are 15–25 cm long, [[leaf shape|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 [[flower]]s are 13–18 mm diameter, with five white petals and 20 creamy-white stamens; they are produced in [[corymb]]s 10–14 cm diameter in late spring, and are [[plant sexuality|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).<ref name=rotach/><ref name=rushforth/><ref name=afm/><ref name=watsonia/> It is a long-lived tree, with ages of 300–400 years estimated for some in Britain.<ref name=watsonia/> {{Inc| 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. {{SCH}} }} ==Cultivation== ===Propagation=== ===Pests and diseases=== ==Varieties== ==Gallery== <gallery perrow=5> Image:Sorbus domestica.JPG|Foliage and fruit Image:Sorbus-domestica.jpg|Foliage and fruit Image:Sorbus-domestica-bark.jpg|Bark Image:Speierling002.jpg|details of a tree Image:Sorbus domestica habit.jpg|Tree </gallery> ==References== <references/> <!--- xxxxx *Flora: The Gardener's Bible, by Sean Hogan.
