| 191. Saxifraga cernua L. 
In not too dry soil, in bogs, heath, herbmats and copses, very often 
in manured soil, rarely in fell-fields. 
Very common throughout the whole area. 
Widely distributed in Greenland without northern or southein 
limit, though more scarce on the southern part of the West coast being 
here defeated in the competition with dense vegetation (Ros.). 
From the shore ascending to the snow-fields. 
In luxuriant habitats flowering abundantly. Ripe fruits were never 
described, only LiNDMARK records unripe capsules filled with ovules. 
A very productive dispersal is effected by means of the small dark-red 
bulblets on the stem. 
As a rule covered by snow in winter. 
V 192. Saxifrasa tricuspidata Rorrs. 
On rocks and coarse gravel, sometimes in dry heath or fell-field. 
Very common throughout the whole area. 
А northern type, in West Greenland common to ca. 64° without 
northern limit. Ascends from the shore to the limit of snowless land, 
occurring even on the Nunataq’s above widely extended snow-fields. 
Abundantly flowering and fruiting except in extremely unfavour- 
able places. I have never seen yellow tints in the corolla, only white 
ones with orange-coloured spots. 
Usually snowless during winter. Not much varying; in the shade, 
for instance in crevices, lengthened green forms occur, the plant, as a 
rule having an intense red colour; they are usually sterile. Often forming 
extensive patches. 
XXV. Rosaseae. 
A 193. Sibbaldia procumbens L. 
In herb-mats and on the edge of willow-copses. 
Disko: Very common on the south coast and in the valleys here and in Disko- 
fjord; rather common on the northern side of Mellemfjord. Here and there on the 
west coast and in the valleys here up to ca. 70°10’ (P.); not observed in the great 
valleys of the Nordfjord nor at the hot springs on the Waygat-coast. 
Mainland: In the southern part of the area in-the district of Holsteinsborg 
rather common; also found northwards, but not continuously. Thus it is common 
along the coast and rather common in the southern part of the archipelago of Ege- 
desminde (with exception of the small barren outside-islets). On the contrary, rare 
in N. Stromfjord, where it is has been recorded by KorneErup; found by us in a single 
place: on the north coast opposite Eqaluarssuit. In the sourroundings of the Syd- 
ostbugt and along the east coast of Disko-Bay up to Torssukatak, rather common, 
but decreasing in frequency northwards. North of Torssukatak only known from 
Sargaq (V.); Majorqarssuatsiag (Bg.); Hare © (P.); and the settlement Nugssuag (P.).
