Sorbus L.
Genus composed of about 244 species, distributed mainly across temperate and cold areas of the Northern Hemisphere. In North Africa it is represented by 6 species, distributed along the Mediterranean area. In this project the traditional nomenclature of the genus is followed, while also considering the recent phylogenetic nomenclatural proposal made by Sennikov & Kurtto (2017), included here in the synonymy of each taxon.
