Range DescriptionThis variety is endemic to Algeria where it occurs to the south-west edge of the Tassili Plateau within the geographical Regions of Maddak, Tassili-Hedjirit and Amiok. Here it has an altitudinal range of 1,430 to 1,830 m with an extent of occurrence (EOO) of 1,000 km (Abdoun and Beddiaf 2002). Its range occupies a strip of 120 km in length and between 6 and 15 km wide and contains 46 sites. The area of occupancy has not been calculated but is likely to be much less than 500 km2 given the small total population size and restricted habitat.
