The allergenic pollen flora of the Maadid region includes 59 species belonging to 19 botanical families and 44 genera and is represented by 47 anemophilous species and 12 entomophilous species responsible for allergies. This flora was inventoried during March to April 2019. Three families, Poaceae, Anacardiaceae and Plantaginaceae dominate respectively. The chorological types of the species show the dominance of the elements of the Mediterranean group over all the other groups, followed by the cosmopolitan group. The biological types of species reveal the dominance of phanerophytes and therophytes over all biological types, hemicryptophytes and geophytes.
