Common in all parts, in the lowland as well as the central highland.
Life-form: H.
Along brooks, especially amongst mosses, around springs, in moist rock-crevices, on
moist gravelly ground.

Saxifraga tridactylites Linn.
K. & M., 1770, p. 307.—Zoega, 1772, p. 7.—Babington, 1871, p-. 308.
Babington, loc. cit., states that he has seen specimens from Granfel (Grænafell)
and from Þingvellir at Mývatn [?]; Zoega cites specimens from Oxeraa (öxará).
There may be some doubt about the correctness of these records; I have seen
no specimens, and it is unlikely that it should have been found in Iceland.
Saxifraga tricusþidata Rottb.
Hooker, in Mackenzie, 1811, p. 422.—Babington, 1871, p. 308.
This species was recorded by Hooker, loc. cit., who saw what he thought might
be this species growing abundantly at Reykjavík. Several other authors after him
have entered it in their lists, but Icelandic specimens provisionally determined as
S. tricuspidata have later been recognized as forms of S. caesþitosa.
S. tricusþidata should be excluded from the Icelandic Flora.

Sorbus aucuþaria is found in most parts of the country, except in the central
highland, whence it has not yet been recorded. Usually the specimens grow rather
