Collection of Arctic Plants. 371 
Whether the same variety has been discovered in other coun- 
tries I know not. A smaller and more densely-tufted state of 
the plant is likewise found in Greenland, but does not exist 
in this collection. A variety, with more or less elongated sur- 
culi, occurs in various parts of Europe in alpine regions. 
25. S. foliolosa. Br. 
Found in Lapland, according to Linnæus, who has de- 
scribed it as a variety of S. stellaris, with which I fear indeed 
that it must be constantly re-united. In Melville Island (Cap- 
tain Parry) ; and, during the second expedition of that com- 
mander, it was found by Mr. Edwards. 
There are only two specimens in Captain Sabine's collec- 
tion; but he likewise detected it in Spitzbergen. 
The true S. stellaris is also found in Greenland; on the 
west coast according to Mr. Greville. It is indigenous to 
Labrador and Canada, according to Pursh; although Dr. Rich- 
ardson did not meet with it in Arctic America. 
26. S. nivalis. 
Principally confined to the high mountains of the north of 
Europe; Scotland being probably its most southern habitat. 
It grows in Lapland, Norway, Iceland, Labrador and Canada 
(Pursh) ; shores of the Arctic Sea (Richardson); and abun- 
dantly on the adjacent islands ; in Spitzbergen ( Martins). 
2T. S. cernua. 
La Peyrouse mentions this as inhabiting the Pyrenees ; and 
upon the authority of Schleicher's Herbarium it is given as a 
native of the Swiss alps. It is rare on the mountains of Scot- 
land ; and exists in Pallas’s collection from Siberia. In Nor- 
way, Lapland and Iceland it is found ; also in Spitzbergen,
