Category. Critically endangered species. Endemic of Armenia. It is found in two floristic regions. The extent of occurrence and area of occupancy are less than 10 km2. The area of distribution is severely fragmented. The threats are restricted of the area of distribution and climate change. It was not included in the first edition of the Red Data Book of Armenia. It is not included in the Annexes of CITES and that of the Bern Convention.
