24. - Siberia (N), Far East (N). - Several reports, numerous counts.
A report of 2n = 52 from northwestern Alaska (Johnson and Packer 1968, for Saxifraga davurica subsp. grandipetala) is problematic. It should belong to this species as it is the only one of the group known from the area and rarely mistaken for anything else.
Geography: Amphi-Beringian: RFE ALA.
Notes: See also Micranthes razshivinii.
Zhmylev: Micranthes calycina is an amphi-Beringian and mainly arctic species. Plants looking like the closely related M. unalaschensis, but differing from it in glandular hairs in the inflorescence, are often found on the Bering Sea islands and in mainland Alaska north to the Seward Peninsula.
