"Sorbus" subgenus "Sorbus"
"Sorbus" Other subgeneraThe whitebeams are members of the
Rosaceae family, in genus "Sorbus " subgenus "Aria". They aredeciduous tree s with simple or lobed leaves, arranged alternately. They are related to therowan s ("Sorbus" subgenus "Sorbus"), and many of the endemic restricted-range apomictic microspecies of whitebeam inEurope 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.The best known species is Common Whitebeam "
Sorbus aria ", but several other species fromEurope andAsia in particular are widely cultivated as ornamental trees.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" Meredith, G. (1851). Love in the valley. Line 207. "Poems"] [http://rpo.library.utoronto.ca/poem/1400.html] .
The berries are a favourite of
bird s, though less palatable (drier, less juicy) than rowan berries. Whitebeams are sometimes used aslarva l food plants byLepidoptera species includingShort-cloaked Moth .The
wood is hard, and suited for woodturning, furniture and tool handles, a tough wood that was used to make cogs before the use ofiron . It is a deep orange when wet, and pale yellow after drying.Etymology
'White' from the colour of the emergent foliage and, later, undersides of the leaves, 'beam' from the
Saxon word for 'tree'.References
