A new species of Brassica sect. Brassica (Brassicaceae) from Sicily

Within the suffruticous cabbages of Brassica sect. Brassica a new species from Sicily, named B.raimondoi, is described and illustrated. This is a chasmophyte restricted to some calcareous rockywalls near Taormina (NE Sicily). The new species is morphologically rather related to B. incana,mainly in sharing similar densely hairy broad amplexicaul leaves and winged petiole, but manydiacritic characters allow these species to be well distinguished. Most relevant difference are whitecorolla, bigger floral peaces, more developed stigma papillae, shorter siliqua, with keeled valvesand smaller seedless rostrum, c. three times shorter fruiting pedicel, smaller seeds with differentcolour and testa micro-sculptures. Analytical keys regarding the current Sicilian taxa belonging tothis section are also provided
