The Flora of Disko Island and Adjacent Coast ol' West Greenland. 91 



fjord rather common. In the inner part of Egedesminde district rather conimon; 

 occurs but sparingly in the archipelago. In X. Stronifjord 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 v. hrerijolia Engl. and |3. rohusta 

 Engl., are only ecological. 



I 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 piaces on the north-Iand and here parti- 

 cularly away from the coast (P.). 



Mai ni and: In the great valley and at Atå on the west coast of Nugssuaq 

 peninsula, and a few piaces south of Atå; but scarce (P.). Between Torssukåtak and 

 the Sydostbugt from several piaces; Eqe (P.); Atå (A. P. Olsen!); Påkitsoq (V.); 

 Ilordleq (Bg.; P.); Jakobshavn (V.); Nunatap tasia (Engell!); Lerbugt (Htz.). 

 Also south of Disko Bay scarce: Egedesminde O (Lundager!); Alångorssuaq at 

 Iginiarfik (K.); N. Strømfjord, Eqaluarssuit (P. & E,). In the district of Holsteins- 

 borg known from the colony itself (Holb.) and Qeqertalik (Brummerstedt). 



Widely ranging in Greenland without southern limit; northwards 

 at least to 78°. Always scarce when occurring. 



In most of the piaces 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. 



I 186. Saxifraga groenlandica L. (S. decipiens Ehrh.), 



In every kind of soil, dry as well as moist, on rocks and in friable 

 soil, in deserted piaces and among other piants, 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.
