Typification of the accepted names in the Jacobaea maritima group (Asteraceae)

All the seven accepted names for species of the Jacobaea maritima group are discussed and typified. Lectotypes are selected for Cineraria bicolor Willd. from the Willdenow Herbarium (B); C. gibbosa Guss. and C. nebrodensis Guss. from the Gussone Herbarium (NAP); Othonna maritima L. from the Clifford Herbarium (BM); Senecio gnaphalodes Sieber from the Brno Herbarium (BRNM) and S. taygeteus Boiss & Heldr. from the Boissier Herbarium (G). A neotype, conserved in the Herbarium of the University of Calabria (CLU), is proposed for Cineraria ambigua Biv. Four needed combinations under Jacobaea Mill. are here proposed for the first time: J maritima subsp. bicolor (Willd.) Peruzzi & al., J maritima subsp. gibbosa (Guss.) Peruzzi & al., Jacobaeo ambigua subsp. nebrodensis (Guss.) Peruzzi & al. and J. ambigua subsp. taygetea (Boiss. & Heldr.) Peruzzi & al.
