Of the 65 sites visited during “Iter Mediterraneum V” in Morocco, 47 are located in 13 of the 20 natural areas, which for chorological purposes, have been recognized in N Morocco. A total of 1689 gatherings was collected in these 13 areas. Study thereof resulted in the incorporation of four new taxa for the catalogue of N Morocco: Adenocarpus complicatus subsp. nainii (Maire) P. Gibbs, Erodium stellatum Delile, Lotus weilleri Maire and Schedonorus mairei (St.-Yves) Dobignard. Several taxa constitute new records for one or more of the 13 areas visited. The percentage of new records varies from 0,3 % in W Rif, the best known natural area of N Morocco, to 38 % (24 new records out of 63 taxa collected) in Tsoul, which is the least known natural area of N Morocco, followed by Ouezzane, with 28 new records out of 153 taxa collected (18,3 %).
