Sorbus
''Sorbus'' is a genus of over 100 species of trees and shrubs in the rose family, Rosaceae. Species of ''Sorbus'' ('' s.str.'') are commonly known as rowan or mountain-ash. The genus used to include species commonly known as whitebeam, chequer tree and service tree that are now classified in other genera (see below). The genus ''Sorbus'', as currently circumscribed, includes only the pinnate leaved species of former subgenus ''Sorbus''. ''Sorbus'' is not closely related to the true ash trees which belong to the genus '' Fraxinus'', although the leaves are superficially similar. Genus As treated in its broad sense, the genus was traditionally divided into several subgenera, however, this treatment was found to be paraphyletic, comprising two disparate lineages within the Malinae subtribe. Consequently, each of the former subgenera have since been elevated into genera in their own right, with the genus name ''Sorbus'' retained only for the rowans. Additionally, it was recogni ...

Aria Edulis
''Aria edulis'', the whitebeam or common whitebeam, is a species of deciduous tree in the family ''Rosaceae''. The tree often forms new shoots around the trunk. Typically compact and domed, the plant has a few upswept branches and the leaves have an almost-white underside. The plant sexuality, hermaphrodite cream-white flowers appear in May, are insect pollinated, and go on to produce scarlet berries, which are often eaten by birds. It is native to most of Europe as well as North Africa (Algeria, Morocco, Tunisia) and temperate Asia (Eastern Anatolia Region, Eastern Turkey, Armenia, Georgia). It generally favours dry limestone and chalk soils. The cultivars ''A. edulis'' 'Lutescens', with very whitish-green early leaves, and ''A. edulis'' 'Majestica', with large leaves, have both gained the Royal Horticultural Society's Award of Garden Merit. The berries are edible when overripe (Bletting, bletted). File:Weilburg - Tiergarten - Mehlbeere.jpg, Tree References Sorbus ...

Torminalis
''Torminalis'' is a genus of plants in the rose family, Rosaceae. The genus was formerly included within the genus ''Sorbus'' as the section ''Torminaria'', but the simple-leafed species traditionally classified in ''Sorbus'' are now considered to form a separate monophyletic group. It is monotypic, being represented by the single species ''Torminalis glaberrima'', commonly known as wild service tree, chequers, and checker tree. This tree is native to Europe, parts of northern Africa and western Asia. A possible second species in the genus has been identified through DNA analysis, but a new scientific description for it has not yet been written. Description ''Torminalis glaberrima'' is a medium-sized deciduous tree growing to about 30 m (100 ft) tall, with a trunk up to 1.3 m in diameter. The bark is smooth and grey when young, becoming scaly and flaking away in squarish plates to reveal darker brown layers when about 30 years old. Young twigs are lightly hairy, quickly becomin ...

Sorbus Aucuparia
''Sorbus aucuparia'', commonly called rowan (, also ) and mountain-ash, is a species of deciduous tree or shrub in the rose family. The tree has a slender trunk with smooth bark, a loose and roundish crown, and its leaves are pinnate in pairs of leaflets on a central vein with a terminal leaflet. It blossoms from May to June in dense corymbs of small yellowish white flowers and develops small red pomes as fruit that ripen from August to October and are eaten by many bird species. It is a highly variable species, and botanists have used different Circumscription (taxonomy), definitions of the species to include or exclude trees native to certain areas. A recent definition includes trees native to most of Europe and parts of Asia, as well as northern Africa. The range extends from Madeira, the British Isles and Iceland to Russia and northern China. Unlike many plants with similar distributions, it is not native to Japan. The plant is frost hardy and colonizes disrupted and inacces ...

Hedlundia
''Hedlundia'' is a genus of plants in the rose family (biology), family (of Rosaceae). They are shrubs or small trees that have a Hybrid (biology), hybrid origin involving crosses between ''Whitebeam, Aria'' and ''Sorbus'' sensu stricto. There are about 48 species are distributed across central, western and southern Europe, Scandinavia, Turkey, the Caucasus, Crimea, and also central Asia. The term ''Hedlundia'' was published in 2017. Description ''Hedlundia'' species are small trees or shrubs, with simple leaves, pinnatilobate (having lobes arranged in a pinnate manner) or basally Pinnation, pinnate with 1–2(–3) leaflets. They are white- or greenish-grey-tomentose (covered with dense, matted, woolly hairs) beneath, with 7–15 pairs of lateral veins, with small to prominent, long, sub-acute to obtuse lobes with a variable number of teeth. They have flowers with white petals and 2–3 Gynoecium, styles. The fruit is medium-sized, orange-red to crimson in colour, with few to sp ...

Rowan
The rowans ( or ) or mountain-ashes are shrubs or trees in the genus ''Sorbus'' of the rose family, Rosaceae. They are native throughout the cool temperate regions of the Northern Hemisphere, with the highest species diversity in the Himalaya, southern Tibet and parts of western China, where numerous apomictic microspecies occur.Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins . The name ''rowan'' was originally applied to the species ''Sorbus aucuparia'' and is also used for other species in the genus ''Sorbus''. Natural hybrids, often including ''S. aucuparia'' and the whitebeam, '' Aria edulis'' (syn. '' Sorbus aria''), give rise to many endemic variants in the UK. Names The Latin name ''sorbus'' was borrowed into Old English as ''syrfe''. The Latin name ''sorbus'' is from a root for "red, reddish-brown" ( PIE ''*sor-/*ser-''); English ''sorb'' is attested from the 1520s in the sense "fruit of the service tree", adopted via French ''sorbe'' from Latin ' ...

Cormus Domestica
''Cormus domestica'', commonly known as service tree 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).Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins .Mitchell, A.'' f. ''(1974). ''A Field Guide to the Trees of Britain and Northern Europe'', p 280. Collins It may be called true service tree, to distinguish it from the wild service tree ('' Torminalis glaberrima''). It is the only species in the monotypic genus ''Cormus.'' It is a deciduous tree growing to (rarely to ) tall with a trunk up to diameter, though it can also be a shrub 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 long, pinnate with 13–21 leaflets long and broad, with a bluntly acute apex, and a serrated margin on the outer half or two thirds of t ...

Chamaemespilus
''Chamaemespilus'' is a genus of shrubs in the family Rosaceae. It is monotypic, being represented by the single species ''Chamaemespilus alpina'', commonly known as false medlar or dwarf whitebeam. It is native to the mountains of central and southern Europe, from the Pyrenees east through the Alps to the Carpathians and the Balkans, growing at elevations of up to 2500 m.Blamey, M. & Grey-Wilson, C. (1989). ''Flora of Britain and Northern Europe''. Description ''Chamaemespilus alpina'' is a deciduous shrub growing to 2–3 m tall. The leaves are spirally arranged, oval-elliptic, 3–7 cm long, with an acute apex and a serrated margin; they are green on both sides, without the white felting found on most whitebeams.

Whitebeam
The whitebeams are members of the family Rosaceae, tribe Malinae, comprising a number of deciduous simple or lobe-leaved species formerly lumped together within ''Sorbus'' s.l. Many whitebeams are the result of extensive intergeneric hybridisation involving the genera ''Sorbus'' (''Sorbus aucuparia'' in particular), ''Aria'', '' Torminalis'' and ''Chamaemespilus''. As an effect, they are commonly apomicts (reproducing solely asexually) and many have very restricted ranges. The best known species is the common whitebeam ('' Aria edulis''), a columnar tree which grows to tall by broad, with clusters of white flowers in spring followed by speckled red berries in autumn (fall). Appearance In many species, the surface of the leaves is an unremarkable mid-green, but the underside is pale to almost white (hence the name) with pale grey or white hairs, transforming the appearance of the tree in strong winds, as noted by the poet Meredith: "flashing as in gusts the sudden-lighted wh ...

Aria (plant)
''Aria'' is a genus of plant in the rose family Rosaceae. It includes some of the deciduous species commonly known as whitebeams, and is native to Europe, the north African mountains and western Asia. Via hybridisation with related genera, it is a main contributor to the genesis of a complex of apomicts of intergeneric hybrid origin, which are also commonly referred to as whitebeams. Description Whitebeams of the genus ''Aria'' are small to medium-sized bushes or trees. The leaves are simple and almost white on the underside. The leaf margins are often serrated. While some species such as common whitebeam ('' Aria edulis'') may grow into sizeable trees of up to height, many species (such as rock whitebeam, '' Aria rupicola'') stay bushy. They bear corymbs of white flowers in spring, and the small, colourful pome fruits ripen in late summer. Whitebeam apomicts Hybridisation events between at least one member of genus ''Aria'' and at least one member of at least one differ ...

Rosaceae
Rosaceae (), the rose family, is a family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus '' Rosa''. The family includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere. Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, blackberries, loquats, strawberries, rose hips, hawthorns, and almonds. The family also includes popular ornamental trees and shrubs, such as roses, meadowsweets, rowans, firethorns, and photinias. Among the most species-rich genera in the family are '' Alchemilla'' (270), '' Sorbus'' (260), ''Crataegus'' (260), '' Cotoneaster'' (260), '' Rubus'' (250), and ''Prunus'' (200), which contains the plums, cherries, peaches, apricots, and almonds.

Scandosorbus
''Scandosorbus'' is a genus of flowering plants in the rose family, Rosaceae. It includes two species of trees native to northern Europe. *'' Scandosorbus intermedia'' – Denmark, Norway, Sweden, Finland, Baltic states, Poland, and Germany *'' Scandosorbus liljeforsii'' – southwestern Sweden Both species are the result of hybridization. ''S. intermedia'' was derived from an ancient hybridization among ''Aria'', ''Sorbus'', and ''Torminalis''. ''S. liljeforsii'' is more recently derived from ''S. intermedia'' × ''Sorbus aucuparia ''Sorbus aucuparia'', commonly called rowan (, also ) and mountain-ash, is a species of deciduous tree or shrub in the rose family.

Karpatiosorbus
''Karpatiosorbus'' (Synonymy: ''Sorbus'' subgenus ''Tormaria'' Májovsky & Bernátová = ''S''. subgenus ''Aria'' x subgenus ''Torminaria'') is a genus of flowering plants in the family Rosaceae, native to Europe, including Crimea, and Algeria. Shrubs or small trees, they appear to have arisen via hybridization events between the clades ''Aria'' (Pers.) Host and '' Torminalis'' Medik. Many of its species propagate solely by apomixis In botany, apomixis is asexual development of seed or embryo without fertilization. However, other definitions include replacement of the seed by a plantlet or replacement of the flower by bulbils. Apomictically produced offspring are geneti .... The genus name of ''Karpatiosorbus'' is in honour of Zoltán Kárpáti (1909–1972), who was a Hungarian (Geo-)Botanist, Taxonomist, Dendrologist and specialist in Sorbus (from central Europe).
