This plant is endemic to the Mediterranean, where it is found in Spain, Sardinia (Italy), Algeria, and Morocco (Euro+Med 2009). It has a very restricted geographical distribution and generally occurs in mountainous regions.

In Morocco, it is known from eight localities (High Imdrhas and Tizi-n-Ouarro in the High Atlas; Itzer, Tazzeka, Timahdit, Azrou and Ifrane in the Middle Atlas; Gada Debdou on the oriental high plateaus). In Algeria, it is present in three localities of the high Tell (Ouach Mountain, Tiaret, Mounts of Tlemcen). In Spain, it is signalled in three provinces in the centre of the country (Ciudad Real, Salamanca, Zamora). In Sardinia, the species is found at only two sites (Arrigoni 2006).

At Mediterranean level, the extent of occurrence is about 800,000 km² and the occupied area does not exceed 400 km².
