Tilia is a genus of about 30 species of trees, native throughout most of the temperate Northern Hemisphere, in Asia (where the greatest species diversity is found), Europe and eastern North America; it is absent from western North America. Under the Cronquist classification system, this genus was placed in the family Tiliaceae, but genetic research by the APG has resulted in the incorporation of this family into the Malvaceae.

Image:Lisc lipy.jpg The trees are generally called linden in North America, and lime in Britain. Both names are derived from the Germanic root lind. The modern forms in English derive from linde or linne in Anglo Saxon and old Norse, and in Britain the word morphed more recently to the modern British form lime. In the United States, the modern German name linden, from the same root, became more common, partly to avoid confusion with any other uses of the name. Neither the name nor the tree is in any way related to the citrus fruit called "lime" (Citrus aurantifolia). Another widely-used common name used in North America is Basswood, derived from bast, the name for the inner bark (see Uses, below).

Tilia species are large deciduous trees, reaching typically 20-40m tall, with oblique-cordate leaves 6-20cm across, and are found through the north temperate regions. The exact number of species is subject to considerable uncertainty, as many or most of the species will hybridise readily, both in the wild and in cultivation; the following list comprises those most widely accepted.

Species
Hybrids and cultivars
  • Tilia × euchlora (T. dasystyla × T. platyphyllos)
  • Tilia × europaea Common Lime (T. cordata × T. platyphyllos)
  • Tilia × petiolaris (T. tomentosa × T. ?)
  • Tilia 'Flavescens' (T. americana × T. cordata)
  • Tilia 'Moltkei' (hybrid, unknown origin)
  • Tilia 'Orbicularis' (hybrid, unknown origin)
  • Tilia 'Spectabilis' (hybrid, unknown origin)

Uses

The tree produces fragrant and nectar-producing flowers, the medicinal herb lime blossom. They are very important honey plants for beekeepers, producing a very pale but richly flavoured honey. The flowers are also used for herbal tea. T. cordata is the preferred species for medical use, having a high concentration of active compounds. It is said to be a nervine, used by herbalists in treating restlessness, hysteria, and headaches. Usually, the double-flowered lindens are used to make perfumes. The leaf buds and young leaves are also edible raw. Tilia species are used as food plants by the larvae of some Lepidoptera species - see List of Lepidoptera which feed on Tilia.

The timber of lime trees is soft and easily worked. It is known in the trade as basswood, particularly in North America. This name originates from the inner fibrous bark of the tree, known as bast (Old English language). Fibre was obtained from the younger wood of the tree. The wood is often used for model building and intricate carving, and for making electric guitar bodies.

The lime tree is the national emblem of Slovakia, Slovenia and the Czech Republic, where it is called lipa (in Slovak and Slovenian) and lípa (in Czech). The lime tree is also the tree of legend of the Slavs. In the Slavic Orthodox Christian world, limewood was the preferred wood for panel icon painting. The famous icons by the hand of Andrei Rublev, including the Holy Trinity (Hospitality of Abraham), and The Savior, now in the State Tretyakov Gallery in Moscow, are painted on limewood. Limewood was chosen for its ability to be sanded very smooth, and for its resistance to warping once seasoned.
