Campanula ruthenica M. Bieb. is shown to be a well-separated species, differing from the closely related C. bononiensis L. by a number of qualitative characters and replacing the latter in the Caucasus and the southern coast of Crimea. The most important distinguishing characters of these species, their images and a map of the distribution of C. ruthenica are given. The lectotypes of Campanula lychnitis Hornem. and C. simplex DC., and the neotype of C. obliquifolia Ten. are designated.
