The Flora of Disko Island and Adjacent Coast of West Greenland. 91 
fjord rather common. In the inner part of Egedesminde district rather common: 
oceurs but sparingly in the archipelago. In N. Stromfjord and the sourroundings 
of Holsteinsborg common (P. & E.). 
Widely distributed in West Greenland (more scarce in East Green- 
land), without southern limit; the northern limit not yet known, but 
to be searched north of 74°30’. Only few habitats known to the north 
of the area. 
In the northern part of the area mainly in the lowland and only 
ascending some two hundred meters. 
Abundantly flowering and ordinarily also fruiting. 
Without doubt sometimes snowless during the winter. 
Not much varying; the forms ». brerifolia Engl. and В. robusta 
Engl., are only ecological. 
| 185. Saxifraga aizoides L. 
On spots with longlasting snow, amongst mosses, sometimes on 
clay and fresh morainic soil. 
Disko: Rare, only collected in a few places on the north-land and here parti- 
cularly away from the coast (P.). 
Mainland: In the great valley and at Ata on the west coast of Nugssuaq 
peninsula, and a few places south of Ata; but scarce (P.). Between Torssukatak and 
the Sydostbugt from several places; Еае (P.); Ata (A. P. Olsen!); Päkitsoq (V.); 
Ilordleq (Bg.; P.); Jakobshavn (V.); Nunatap tasia (Engell!); Lerbugt (Htz.). 
Also south of Disko Bay scarce: Egedesminde © (Lundager!); Alangorssuaq at 
Iginiarfik (К.); N. Stromfjord, Eqaluarssuit (P. & E,). In the district of Holsteins- 
borg known from the colony itself (Holb.) and Qegertalik (Brummerstedt). 
Widely ranging in Greenland without southern hmit; northwards 
at least to 78°. Always scarce when occurring. 
In most of the places not flowering till late in the summer, hence 
the fructification usually fails. When sterile, very easily overlooked 
because of its diminutiveness and occurrence in mosses. 
Hibernates covered by snow. 
| 186. Saxifraga groenlandica Г. (5. decipiens Eurn.), 
In every kind of soil, dry as well as moist, on rocks and in friable 
soil, in deserted places and among other plants, now and then in man- 
ured soil. Very common throughout the whole area. 
Widely distributed in Greenland without northern or south- 
ern limit. Ascending to the limit of vegetation. 
Flowers and fructificates abundantly. 
Often snowless during winter. Varying very much, most of the 
varieties described seem to be mere ecological forms.
