'''''Sorbus''''' is a [[genus]] of about 100–200 species of [[tree]]s and [[shrub]]s in the [[subfamily]] [[Maloideae]] of the Rose [[family (biology)|family]] [[Rosaceae]].  Species of ''Sorbus'' (s.l.) are commonly known as [[whitebeam]], [[rowan]], [[service tree]], and [[Sorbus aucuparia|mountain ash]].  The exact number of species is disputed depending on the circumscription of the genus, and also due to the number of [[Apomixis|apomictic]] [[Apomixis|microspecies]], which some treat as distinct species but others group in a smaller number of variable species.  Recent treatments <ref name=Robertson>Robertson, K. R., J. B. Phipps, J. R. Rohrer, and P. G. Smith. 1991. A Synopsis of Genera in Maloideae (Rosaceae). ''Systematic Botany'' '''16''': 376–394.</ref><ref name=McAllister>McAllister, H. 2005.

''Sorbus'' is unrelated to the true ash trees which belong to the genus ''[[Fraxinus]]'', although the leaves are superficially similar.

*'''''Sorbus'' subgenus ''Sorbus''''' (genus ''Sorbus'' s.s.), commonly known as the '''[[rowan]]''' (primarily in the UK) or '''mountain ash''' (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.)

:*'''''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''. Distribution: temperate northeast [[Asia]].

*'''''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. Distribution: mountains of southern [[Europe]].

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