Campanula dersimensis Fırat & Yıldırım, a new species endemic to the E Anatolian region of Turkey, is described and
illustrated. It is currently known from two localities in Tunceli province (Dersim). Campanula dersimensis shows similarities to C.
quercetorum Hub.-Mor. & C. Simon and C. yildirimlii Kit Tan & Sorger. A close relationship of the three taxa is also supported by
phylogenetic analyses based on the nuclear-encoded ribosomal internal transcribed spacer (ITS) region. Diagnostic morphological
characters are discussed and compared with those of closely related taxa. Campanula dersimensis is easily distinguished from
related species, especially by its retrorsely hairy stem and leaf surface, to 1 mm long calyx appendages and glabrous and light
greenish yellow to yellowish white corollas.
