net Stenbræk. English: Meadow Saxifrage.
This species was first recorded by Glie-
mann, loc. cit., and by Vahl, who considered
it a native of Iceland. No specimens were,
however, in evidence to corroborate these
earlier records, but in 1934 Director Árni
Friðriksson found it at Fossvogur near Rey-
kjavík. It was growing there in cultivated
fields, and has most probably been in-
troduced in very recent times. When I
visited the locality on the 15th of June 1934
it was thriving well, the specimens measur-
ing from 20—30 cm in height. It was in
full flower.
It is very doubtful whether this species
Fig. 108. Saxifraga foliolosa R.Br. can actually be looked on as naturalized in
from Vatnsfjall. 1:1. Iceland.

Frequent in most parts in the lowland, as well as in the central highland. On
the rather barren flats in front of the glacier of Hofsjökull, at Arnarfell hið mikla I
found it growing abundantly in 1934.
var. ochroleuca Omang (in Nytt Magasin for Naturvid., Bd. 76, 1937, p. 293)
has sepals ovate to ovate-oval, nearly glabrous; petals light yellow without darker
stains, broader than in the type, oval to oboval. Found by Omang at Reykir near
Hrútafjörður, 1936.
Stefánsson (loc. cit., 1924) mentions a variety alþina Engl., with broader, nearly
spathulate leaves, corolla larger and bright yellow. Found in several places in N.
and E.
Life-form: H.
On moist, bare soil, on rocks and stony soil, in moors, fell-field, in moss on the edge
of brooks, near hot springs, etc.
