Saxifraga nathorstii, 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] and has 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 and habitat
Commonly found on moist sandy to gravelly soils, e.g. in riverbeds sand and gravel or desiccated ponds.[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]
