Icelandic : Jöklasóley. Danish : Is-Ranunkel.
Rather common in all parts of the hills, except in S. whence it has not yet been
recorded. H. Jónsson, however, seems to take it for granted that it must be found
high up in the hills in S. (H.J., 1905, p. 71). See fig. 91.
Life-form: H.
On gravelly flats and stony ground in the hills, up to the snow-line.
Flor. VI—VII; fr. mat. (?).
Max. height: 16 cm; average : 8 cm.
Geogr. area: Greenl. : E. 65°30'—77°40'.—Eur.: Fær.; northern Scandinavian mts.,
N. Finland and Russia, Jan Mayen, Spitsbergen, mountains of central and S. Eur.
Ranunculus hederaceus Linn.
K. & M., 1770, p. 208.—Baring-Gould, 1863, p. 424.—Babington, 1871, p. 291.
Recorded by K. & M., loc. cit., without locality; Baring-Gould records Víði-
mýri, N., as a locality. Most likely specimens of R. hyperboreus have been interpreted
as this species. It should be excluded from the Icelandic Flora.
