• Resumen

  • The taxa of Cotoneaster Medik. (Rosaceae) from NW Africa (Morocco, Algeria and Tunisia) have been revised. The taxonomic position of C. atlanticus G. Klotz is justified and the occurrence of C. granatensis Boiss. in Morocco is confirmed. Diagnostic characters, descriptions, detailed illustrations and distribution maps are given for both taxa. Morphological characteristics of C. atlanticus and C. granatensis are compared with the related C. nummularius Fisch. & C. A. Mey. and C. racemiflorus (Desf.) K. Koch.
