It is distributed throughout the western Iberian Peninsula in the Coastal Lusitan-Andalusian and Lusitan-Extremadurean biogeographical territories. It is positioned in the Ulici argentei-Cistion ladaniferi, Lavanduletalia stoechadis, Cisto-Lavanduletea. The new associations Anthyllido maurae-Ulicetum jussiaei, Sedo albi-Cistetum crispi and Thymetum congesti are also described.
