The plant is listed in the regional Red Books of the Russian Federation – namely the Red Books of YANAO and H-MAO. The location of this species installed in the upper river Krestovaya (tributary of the Langotyugan river), close to the centerline of the Polar Urals, on the Western border of the Yamalo-Nenets Autonomous district (YANAO) of the Russian Federation.
