[Draft of the Aix-en Provence pollen calendar]

Because of some divergences between the pathologics of Aix and the pollinic accounts found by the spore-trap of Marseilles, a spore-trap has been installed since the beginning of 1997 in Aix hospital to prove that these two sites are specific for pollen identification and dates of pollinisation as well. After three years of measures, the correlation between the vegetation of Aix and the pathological symptoms is established. They are coherent with those published in other sound European countries and confirm the "mediterreean" feature of Aix.
