'''''Laurus''''' is a genus of [[evergreen]] [[tree]]s belonging to the Laurel family, [[Lauraceae]]. The genus includes three species, whose diagnostic key characters often overlap (Mabberley 1997).
*'''''Laurus azorica''''' (Seub.) Franco, [[synonymy|syn.]] ''L. canariensis'' Webb & Berth. Known as Azores Laurel, or by the Portuguese names ''Louro, Loureiro, Louro-da-terra'', and ''Louro-de-cheiro'', is native to the [[laurisilva]] forests of the [[Azores]].
*'''''Laurus nobilis''''' [[Carolus Linnaeus|L.]], known commonly as [[Bay Laurel]], True Laurel, Sweet Bay, Grecian Laurel, or simply Laurel, is the source of the spice [[Bay leaf]]. It was also the source of the [[Laurel wreath]] of ancient [[Greece]]. It is distributed across the [[Mediterranean region]] from [[Spain]] to [[Greece]].
*'''''Laurus novocanariensis''''' Rivas Mart., Lousã, Fern. Prieto, E.Díaz, J.C. Costa & C. Aguiar, also known as the same portuguese names as ''L. azorica'', is native to the [[laurisilva]] forests of [[Madeira Islands]] and [[Canary Islands]], and also locally in [[Morocco]].
Fossils dating from before the [[ice age]]s 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 [[Macaronesia]]n 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].
