The following are with us subalpine species ; they occur in 

 our alpine region (to which most of them properly belong), but 

 also oat of it, at least in one or two places. 



Alsine Groenlandica. Empetrum nigrum. 



Geum radiatum. Platanthera obtusata. 



Arnica mollis. Scirpus csespitosus.

All of these except Geum radiatum, Arnica mollis, and Carex 

 scirpoidea, are also European. The last grows in Greenland. 



The following European species have not been detected in any 

 properly alpine habitat with us (where they might be expected 

 to occur), but elsewhere, three of them {Saxifraga aizoides and 

 Carex gynocrates) in stations not even subalpine : 



Saxifraga oppositifolia. Artemisia borealis. 



Saxifraga aizoides. Juncus Stygius.
