Taxon discussion

A very local and range-restricted species, previously known from the Greek and the Bulgarian sides of Mt. Orvilos (also known as Ali Botuš), although Wood et al. (2015) omit Greece in the distribution range of the species. Specimens from Mt. Slavjanka, Bulgaria ( Wood et al. 2015) and observations from Mt. Angistro, Greece ( Tan and Kofinas 2020) slightly extended the species’ area of occurrence. The new locality on Mt. Achladovouno (Fig. 16 ), ca. 100 km to the SE of Orvilos, is isolated and forms the easternmost border in the species’ distribution (Fig. 17 ). It was not found together with either C. lineatus L. or C. boissieri subsp. compactus (Boiss.) Stace, the presumed parents of C. suendermannii in case the hybridogenous origin is hypothesised.
