 descends to the level of the sea. 



On harren j^roiind, dry or moist, on alpine heaths, and in places that 

 are irrijj^ated hy water frf)m the eternal snow. It can endure very hard conditions 

 of life, e. i^. on prominent stones and rocks where the protecting snow is 

 blown awa\- and which are covered with ice diirint^ the winter and exposed 

 to div and very cold winds during the short summer. At such stations it 

 is short, slender, and decumbent. More erect and turgid (f. taurica Schaer.) 

 at moist places.

An Arctic species which, however, advances southwards along our 

 west coast to Karmoen north of Stavanger. I have only seen it in Alten. 

 It was quite common there on the mountains on gravelly soil in depressions 

 in the rocks which were occasionally moistened by streaming water.
