C. laxa is an arctomontane species with predominantly Asian – western North American   GoogleMaps distribution and a single locality in the European Arctic (Konstantinova & Lavrinenko, 2002) and another in the subarctic ( Borovichev, 2013), which presumably represent post-glacial invasion (Konstantinova & Mamontov, 2010).
