The whitebeams are members of the Rosaceae family, comprising subgenus Aria of genus Sorbus, and hybrids involving species of this subgenus and members of subgenera Sorbus, Torminaria and Chamaemespilus. They are deciduous trees with simple or lobed leaves, arranged alternately. They are related to the rowans (Sorbus subgenus Sorbus), and many of the endemic restricted-range apomictic microspecies of whitebeam in Europe are thought to derive from hybrids between S. aria and the European rowan S. aucuparia; some are also thought to be hybrids with the wild service tree S. torminalis, notably the service tree of Fontainebleau Sorbus latifolia in French woodlands.

Appearance
The surface of the leaf is an unremarkable mid-green, but the underside is almost white (hence the name) transforming the appearance of the tree in strong winds, as noted by the poet Meredith: "flashing as in gusts the sudden-lighted whitebeam". It is also described as the "wind-beat whitebeam" in Gerard Manley Hopkins' poem "The Starlight Night".
Ecology
The berries are a favourite of birds, though less palatable (drier, less juicy) than rowan berries. Whitebeams are sometimes used as larval food plants by Lepidoptera species including Short-cloaked Moth.
Uses
This tree is grown in parks and large gardens. The cultivars S. aria 'Lutescens' and S. aria 'Majestica' have gained the Royal Horticultural Society's Award of Garden Merit.
The tough, hard wood is a deep orange when wet, and pale yellow after drying. It suited for woodturning, and was used for furniture, tool handles, and cogs before the use of iron.
The berries are edible and are often made into jelly.
