Silene orphanidis Boiss.
Silene orphanidis Boiss is a rare local endemic that occurs only in places around the top of Mount Athos and at an altitude ranging from 1700 to 2000 m. It is found in rocky slopes and slopes of limestone rocks in semi-shaded places, near and above the tree limit, with a very small population of 60 to 100 individuals. The conservation status of the species, which is listed in Annex II of the Directive 92/43/EC, was assessed as Favourable based on the latest national report (2007-2012), while according to the IUCN Red List, the species has been classified as Endangered (EN). The species is not in direct threat due to the special conditions prevailing on Mount Athos. The small size of its population could be considered as a potential risk.
