Diversity in the population of Brassica incana Ten. (Cruciferae) in Sicily

henotipic diversity in Sicilian populations of Brassica incana Ten. (Cruciferae) is here ana- lyzed in comparison with the only one known population of B. raimondoi Sciandrello et al., taxonomic close species recently described from the coastal relief of eastern Sicily. The analysis of diagnostic characters of these two taxa does not reveal significant differences that justify a treatment at species level of the population of B. raimondoi. On this base, the authors deemed to include this taxon in the infraspecific variability of B. incana and consider most appropriate the rank of subspecies. Therefore is here proposed the establishment of the trinomial com- bination B. incana subsp. raimondoi
