Abstract
Veronica ersin-yucelii (subg. Pentasepalae, Plantaginaceae) is described and illustrated as a new species. It grows on marble rocks and screes, in one single site in Central Anatolia (Eskişehir Province), at elevations from about 1700 to 1820 metres above sea level. Diagnostic features are also given to enable comparison with the most similar species, V. caespitosa Boiss. and V. multifida L., especially regarding the indumentum, habit, inflorescence, bracts, seeds and leaves. The geographical distribution of the new species is mapped. Notes about its ecology and conservation status are also presented.
