Sorbus (ancient Latin name of S. domestica). Including Aria, Cormus, Micromeles, and Torminaria. Rosaceae. Ornamental woody plants grown for their handsome foliage, attractive white flowers and ornamental usually red fruit. Deciduous trees or shrubs: lvs. alternate, stipulate, simple and serrate or odd-pinnate, folded or rarely convolute in the bud: fls. in compound corymbs; sepals and petals 5; stamens 15-20, with red or yellow anthers; carpels 2-5, either partly free above and half superior or wholly connate and quite inferior; styles free or connate at the base: fr. a 2-5-loculed pome, usually rather small; the cells with cartilaginous or leathery walls, each with 1 or 2 seeds. Closely allied and often referred to Pyrus, from which it is chiefly distinguished by its compound infl. and by the fls. being in most species more or less perigynous; the frs. are usually smaller and berry-like.—About 80 species distributed throughout the northern hemisphere, in N. Amer., south to N. C. and New Mex., in Asia south to the Himalayas. The frs. of some species, as S. domestica, S. torminalis, S. Aucuparia var. dulcis and var. rossica are edible and are made into preserves in Europe; the strong and close-grained wood of S. torminalis and S. domestica is used for handles of tools and for similar small articles. The sorbuses are handsome trees or shrubs with graceful pinnate or with simple foliage sometimes silvery white beneath, and with showy clusters of small white rarely pinkish flowers in spring, followed by red or rarely whitish or brown fruits usually berry-like, rarely larger and apple- or pear-shaped. Most of the pinnate-leaved kinds are hardy North except some Asiatic species and S. domestica, which seem tender north of Massachusetts; they are chiefly inhabitants of mountainous regions, and the northern species, as S. americana and S. decora, do not thrive well in warmer and drier climates, while the simple-leaved species, as S. alnifolia, S. intermedia, S. Aria, and S. torminalis, endure drought and heat well and have proved hardy at least as far north as Massachusetts. The trees are often attacked by borers. Propagation is by seeds sown in fall or stratified, also by layers. Varieties and rarer kinds are usually budded or grafted on allied species, but most kinds will grow on S. Aucuparia or S. americana and on hawthorn. They all have handsome foliage, which usually turns orange-red in fall; their fruits are showy and often remain on the branches the whole winter if not eaten by birds. They are not particular as to the soil and are well suited for planting on rocky hillsides. Those of the Aucuparia group are more adapted for cool and moist mountain regions; those of the Aria and Torminaria group, which grow especially well on limestone soil, are suited to warmer and drier climates. S. hybrida is sometimes used as a small-sized avenue tree on account of its regular pyramidal habit. CH The above text is from the Standard Cyclopedia of Horticulture.

Species

As treated in its broad sense, the genus is divided into two main and three or four small subgenera (with more recent generic assignments in parentheses)^wp:

• Sorbus subgenus Sorbus (genus Sorbus s.s.), commonly known as the rowans (primarily in the UK) or mountain ashes ( in both North America and the UK), with compound leaves usually hairless or thinly hairy below; fruit carpels not fused; type species Sorbus aucuparia (European Rowan). Distribution: cool-temperate Northern Hemisphere. (Genus Sorbus s.s.)^wp

• Sorbus subgenus Aria (genus Aria), the whitebeams, with simple leaves usually strongly white-hairy below (hence the name, from German Weissbaum, 'white tree'); fruit carpels not fused; type species Sorbus aria (Common Whitebeam). Distribution: temperate Europe & Asia^wp.

• Sorbus subgenus Micromeles (genus Aria), an indistinct group of a few east Asian species (e.g. Sorbus alnifolia, Korean Whitebeam) with narrow leaves; doubtfully distinct from and often included in subgenus Aria^wp. Distribution: temperate northeast Asia^wp.

• Sorbus subgenus Cormus (genus Cormus), with compound leaves similar to subgenus Sorbus, but with distinct fused carpels in the fruit; just one species, Sorbus domestica (Service Tree)^wp. Distribution: North Africa, warm-temperate Europe, West Asia^wp.

• Sorbus subgenus Torminaria (genus Torminaria), with rather maple-like lobed leaves with pointed lobes; fruit carpels not fused; just one species, Sorbus torminalis (Wild Service Tree)^wp. Distribution: temperate Europe^wp.

• Sorbus subgenus Chamaemespilus (genus Chamaemespilus), a single shrubby species Sorbus chamaemespilus (False Medlar) with simple, glabrous leaves and pink flowers with erect sepals and petals^wp. Distribution: mountains of southern Europe^wp.

• Hybrids are common in the genus, including many between the subgenera; very often these hybrids are apomictic (self-fertile without pollination), so able to reproduce clonally from seed without any variation^wp. This has led to a very large number of microspecies, particularly in western Europe (including Britain) and parts of China^wp.
