Tilia is a
genus of between 30 and 45
trees in the
Northern Hemisphere, in
Asia (where the greatest species diversity is found),
Europe and eastern
North America; it is absent from western North America.
The trees are generally called linden in North America, and lime in Britain. Both names are went from the
Germanic root lind. The modern forms in
English went from linde or linne in
Anglo Saxon and
old Norse, and in
Britain the word transformed more recently to the modern British form lime. In the
United States, the modern
German name Linde, from the same root, became more common, partly to avoid confusion with any other uses of the name.
Tilia species are large
deciduous trees, reaching typically between 20m and 40m tall, some species grow as
shrubs. Plants of this genus are found through the north temperate regions.
