The affinity with the populations in
Iceland and North-America
Previously it has been mentioned that it is
impossible to distinguish Salix arctica in
Faroe Islands from the population of the
same species in Iceland. As in the case of
the Faroese material, botanists had doubts
about the determination of this species in
Iceland. Most of the times it was treated as
Salix glauca (Gronlund, 1881; Stefánsson,
1901; 1924; 1948; Ostenfeld and Gróntved,
1934; Love, 1945) and as previously men-
tioned Floderus determined the Icelandic
specimens he examined as double- or
triplehybrids like the Faroese samples.
Áskell Lóve (1950: 37-38) points out
that what until then had been named Salix
glauca in Iceland clearly differed from that
species in Sweden. He had been told that it
was a species from arctic North America
named Salix callicarpaea Trautv. Since
that the Icelandic population has been con-
sidered to be connected to some North
American representative of the Salix glau-
ca-complex and either named S. calli-
carpaea Trautv. (Lóve and Lóve, 1956;
Rechinger, 1964; Hylander, 1966; Bjama-
son, 1983; Kristinsson, 1986), S. cordifolia
Pursh. (Lðve, 1970; 1983), S. cordifolia
subsp. callicarpaea (Trautv.) Lðve (1950)
