Taxon discussion

A range-restricted subspecies, endemic to NE Greece, Bulgaria and North Macedonia ( Dimopoulos et al. 2013). Cerastium decalvans has been reported from the mountains of Belles, Orvilos, Menikio, Pangeo, Falakro and Lekani in the floristic region of NE Greece ( Strid 1986); however, the only records of subsp. Cerastium orbelicum orbelicum come from Mt. Belles and Mt. Menikio ( Strid 1997a). The locality on Mt. Achladovouno is the easternmost border limit of the subspecies’ distribution in Greece.
