Tue species is litoral, growing in pools in the upper 

 part of the zone. At West-Finmarkcn, where I met with 

 it in great abundance, I have seen transitions between the 

 forms typica and crassuiscula Kjellm., and I think they 

 hardly may be reG:arded as different forms. The few speci- 

 mens that I have seen at East-Finmaiken are most nearly 

 to be related to the typical form. Cp. Kjellm. 1, c. 



Distributior: Found at Vardo, Kiberg and Bugonæa, 



very rare
