The lectotypification of nine Linnaean names in the genus Campanula (C. decurrens, C. erinoides, C. graminifolia, C. hederacea, C. hybrida, C. linifolia, C. mollis, C. thyrsoides, C. uniflora) is discussed. The designation of the nomenclatural types is based on the consultation of Linnaeus's original material and the literature cited in the respective protologues. The names are lectotypified using specimens from LINN except for C. erinoides, C. graminifolia, and C. hybrida, which are lectotypified by illustrations of Hermann (1687), Barrelier (1714), and Morison (1680), respectively. An epitype is designated for C. graminifolia due to ambiguity in the interpretation of the lectotype.
