Notes: Piirainen (2001) accepted two subspecies of Caltha palustris in northwestern Europe: subsp. palustris and subsp. radicans (= subsp. arctica). When the small-flowered, low-grown, and rooting plants in the European mountains are merged with the arctic plants, the names C. radicans 1807, subsp. radicans 1863, and var. radicans 1886 have priority before the more well-known names C. arctica 1823, subsp. arctica 1968, and var. arctica 1892. Subspecies radicans is the main arctic race of Caltha and is very widespread but absent from northeastern North America and Greenland.
