Icelandic: Klettafrú, Þúsunddygðajurt. English: Pyramidal Saxifrage.
Found in a good many places in E., from Seyðisfjörður in the north to
Lónsheiði in the south. In S. here and there from Kap Horn westward to Síða.
Olafsen & Povelsen, loc. cit., records it from West-Iceland, and Zoega, loc. cit.,
from Hekla, but these records are pos-
sibly due to mistakes. See fig. 107.
var. multicaulis Stef., with several stems,
and long-stalked flowers from the leaf-
axils (Almannaskarð, D8, St.St., 1894).
Life-form: Ch.
In rock-clefts, on rock-ledges; often in
crevices in vertical, southward-exposed
rock-walls.
Flor. VII—VIII; fr. mat. VII—VIII.
Max. height: 40 cm : average : 18 cm.
Geogr. area: Eur.: Norway (60°25'—
70° 15' N. lat., central Sweden, Jámt-
land and Lapland. Alps, Pyrenees.
Saxifraga cuneifolia Linn.
S. punctata (cuneifolia), Gliemann, 1824,
p. 142.—Hjaltalín, 1830, p. 194.—Ba-
bington, 1871, p. 307.
As Babington remarks, loc. cit., this is certainly a mistake; it should be excluded
from the Icelandic Flora.
247. Saxifraga foliolosa R.Br., Chloris Melvilliana in Parry, Journ. Voy.
(1821) p. 275.
S. stellaris L. var. comosa Poir., O. & Gr., 1934, p. 84.
Icon.: Linn. Fl. lapp. (1737) tab. 2, fig. 3.—Fig. 108 in the present work.
This pronounced high-arctic species was found by Thorv. Sorensen on Vatnsfjall
at Mælifell within Skagafjörður, N., in 1930; it was growing there at an altitude
of about 800 m s. m.
Life-form: H.
On moist bare soil in móland.
Height: c. 5 cm.
Geogr. area: Northern N. Am. Labrador; Alaska to Colorado.—Greenl.: W. 61°35'
—83°. E. 69°25'—77°.—Eur.: Central Norway, Kola Penins., Novaya Zemlya,
Spitsbergen.—Asia: Siberia by the Yenisei, Chukchee Land, Sayansk mts., Trans-
baikal, Okhotsk, Kamchatka.
Saxifraga geranioides Linn.
Preyer & Zirkel, 1862, p. 366.—Babington, 1871, p. 308.
This species is only known from the Pyrenees, and it is very unlikely that it
should have been found in Iceland.
