Notes: Elven and Murray: Yurtsev (PAF proposal) accepted from the Arctic five hybrid species assumed developed from crosses between species of sect. Aureae and sect. Niveae. A sixth has been added later. Four of the proposed species are reported from Russia or predominantly from Russia. Populations (biotypes) resulting from crosses of similar parentage are known also from northern North America, Greenland, and northwestern Europe. The majority of North American and European botanists have not considered them taxa. We cannot at the same time accept such plants as species for Russia and as nameless biotypes elsewhere. All the proposed species are therefore entered provisionally until further investigated.
