Laurus nobilis

Laurus

This article is about the Laurus tree. For information on the church hierarch, see Metropolitan Laurus''.

Laurus is a genus of evergreen trees belonging to the Laurel family, Lauraceae. The genus includes three species, whose diagnostic key characters often overlap (Mabberley 1997).

Fossils dating from before the ice ages show that species of Laurus were formerly distributed more widely around the Mediterranean and North Africa, when the climate was more humid and mild than at present. It is currently thought that the drying of the Mediterranean basin during the ice ages caused Laurus to retreat to the mildest climate refuges, including southern Spain, Portugal and the Macaronesian islands. With the end of the last ice age, L. nobilis recovered some of its former range around the Mediterranean.

A recent study found that native stands classified as L. nobilis in northern Spain shared greater genetic and morphological similarity to L. azorica than to populations of L. nobilis native to France and Italy [Arroyo-Garcia et al 2001].
