Extremely variable, particularly in indumentum and floral and fruit characters, and local variants have been given specific, subspecific or varietal rank. Variants transitional to 8 appear to be frequent in the Balkan peninsula and further work is required to understand the structure of this complex. The name C. hungaricum Simonkai was originally applied to plants from the northern edge of the range, where there is a tendency for the indumentum to be rather sparse.
