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 Linnaeus, 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- 

 tai?i 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). 



27. 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,
