Fraxinus (Tourn.) L.
Genus composed of about 60 species of trees, distributed mainly throughout the northern Hemisphere. In North Africa it is represented by 2 species, both in the Mediterranean area, but with very different ecology. F. angustifolia is a tree typical of riverbeds and soils that are very humid throughout the year, while F. dimorpha generally behaves like a forest tree.
