Abstract: Le nombre chromosomique de douze taxa appartenant à onze familles d’angiospermes marocaines sont rapportés: Achyranthes sicula n = 40; Bidens pilosa 2n = 60 et n = 30; Carrichtera annua 2n = 16; Clematis cirrhosa 2n = 16; Eryngium atlanticum n = 8; Parietaria judaica n = 13; Parietaria lusitanica subsp. lusitanica n = 10;  Scrofularia canina 2n = 24; Sixalix atropurpurea 2n = 16; Solanum sodomaeum n = 12;  Spergularia diandra 2n = 18 et Urginea maritima n = 30. La plus part des ces nombres sont rapportés pour la première fois sur des populations marocaines. Des microphotographies mitotiques ou méiotiques ainsi qu’un bref commentaire sont signalés pour chaque taxon. Chromosome numbers of twelve taxa from eleven families of Moroccan angiosperms are reported: Achyranthes sicula n = 40; Bidens pilosa 2n = 60 et n = 30;  Carrichtera annua 2n = 16; Clematis cirrhosa 2n = 16; Eryngium atlanticum n = 8; Parietaria judaica n = 13; Parietaria lusitanica subsp. lusitanica n = 10;  Scrofularia canina 2n = 24; Sixalix atropurpurea 2n = 16; Solanum sodomaeum n = 12;  Spergularia diandra 2n = 18 and Urginea maritima n = 30. Most of those numbers were reported for the fi rst time in Moroccan populations. Mitotic or meiotic metaphases microphotographs and brief comments are detailed for each taxa studied.
