Ranunculus glacialis, the glacier buttercup [1] or glacier crowfoot, is a plant of the family Ranunculaceae. It is a 5-10(-20) cm high perennial herb. Often with a single relatively large (1.8 - 3.8 cm) flower, with 5 petals first white later pink or reddish. The underside of the 5 sepals are densely brown-hairy. The leaves are fleshy, shiny, and deeply loped, forming 3 leaflets. [2] [3] Ranunculus glacialis reported (from Greenland material) to have a diploid chromosome number of 2n = 16. [2]

Distribution and habitat

Ranunculus glacialis is an Arctic–alpine species, found in the high mountains of southern Europe ( Alps, Pyrenees, Carpathians, Sierra Nevada) as well as on the Scandinavian peninsula, Iceland, the Faroe Islands, Jan Mayen, Svalbard, eastern Greenland [4] [5] and Finland, where is endangered and protected. [6]

It has been described as being one of the highest-ascending plant in the Alps, flowering at over 4,000 m. [7]

It is found in fell-field and snow-bed sites, on edges of meltwater streams. [6]

Subspecies

Several subspecies are described. [8]

One subspecies, Ranunculus glacialis subsp. chamissonis, is found on either side of the Bering Strait in Siberia, Russia and Alaska, U.S..
