Saxifraga nathorstii, or Nathorst's saxifrage, is a species of flowering plant belonging to the family Saxifragaceae. [1] Saxifraga nathorstii is a putative allotetraploid hydrid between S. aizoides and S. oppositifolia, [2] [3] and morphologically intermediate, even in terms of pollen, [4] between the parent species.

It is native and endemic to Greenland, [1] with a limited distribution in Northeast Greenland.

Description

It is a somewhat densely tufted perennial with 3 – 6 cm high ascending stems. The singular sordid pink to fleshy coloured flowers are 8 – 15 mm wide, have 5 petals, which do not overlap, and 5 sepals 2 – 3 mm long.

Stems with alternate to opposite 4 – 9 mm long lance-shaped leaves with a pointed oval apex. [5]

Distribution ranges from Danmarks Island (70°30'N) to Jonsbu, Hochstetter Foreland (75°20'N). [6] [7]

Conservation status

Despite is its limited distribution range and endemic status it is not a threatened species. [8] The Greenland red list 2018 assesses the species to be of Least concern, but a species of national responsibility due to it endemic status. S. nathorstii have not been assessed on the IUCN red list. [9]
