Notes: The widespread "Meadow sorrel" - subsp. acetosa (Rumex acetosa s. str.) - is comparatively uncomplicated and differs in some assumed independently inherited characters from the majority of the northern and alpine plants, foremost in the ochrea with long fringes in the margin in subsp. acetosa vs. subentire in the others but also in blades with acute vs. obtuse basal lobes. Subspecies acetosa reaches the Arctic as native in Norway and northern European Russia. In Iceland and Greenland it is an archaeophyte from approx. A.D. 800 or later and possibly not present in the Arctic in Iceland (there largely replaced by the native subsp. islandicus). However, it is present as a stable adventive in Jan Mayen, the Norwegian island included in the floristic region 'Ic' in the distribution table.
