Sorbus aucuparia, commonly called rowan (/ ˈ r oʊ ən /, [3] also UK: / ˈ r aʊ ən /) 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.
The best-known species is the European rowan Sorbus aucuparia, a small tree typically 4–12 metres (13–39 ft) tall growing in a variety of habitats throughout northern Europe and in mountains in southern Europe and southwest Asia.
Sorbus is a genus of over 100 species of trees and shrubs in the rose family, Rosaceae.Species of Sorbus are commonly known as rowan or mountain-ash.Currently, species commonly known as whitebeam, chequer tree and service tree are classified in other genera (see below), so that genus Sorbus includes only the pinnate leaved species of former subgenus Sorbus.

The tree species Sorbus americana is commonly known as the American mountain-ash. [4] It is a deciduous perennial tree, native to eastern North America. [5]The American mountain-ash and related species (most often the European mountain-ash, Sorbus aucuparia) are also referred to as rowan trees.
Hedlundia pseudomeinichii, known as false rowan [2] and Catacol whitebeam, is a rare species of tree endemic to the Isle of Arran in south-western Scotland.It is believed to have arisen as a hybrid of the native European rowan (Sorbus aucuparia) and the cut-leaved whitebeam (Hedlundia pseudofennica) which is in turn a rowan/Arran whitebeam (Hedlundia arranensis) hybrid. [3]
Hedlundia species are small trees or shrubs, with simple leaves, pinnatilobate (having lobes arranged in a pinnate manner) or basally 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.
The whitebeams are members of the family Rosaceae, comprising the genus Aria.They are deciduous trees with simple or lobed leaves, arranged alternately. They are related to the rowans, and many of the endemic restricted-range apomictic microspecies of whitebeam in Europe are thought to derive from hybrids between the common whitebeam and the European rowan.
