the zone, on a depth of 1 — 2 fathoms, sometimes in the lo- 

 wer part on a depth of about 16 fathoms. It occurs on open 

 coast as well as in the interior of deep bays, in scattered 

 individuals. 



Distribution: Probably sparingly spread along the whole 

 coast. I have found it at Berlevaag and at Kirkenas in 

 Sydvaranger.

At the only place where I met with this species, it grew 

 in a rock-pool within the lower part of the litoral region, 

 on much exposed shore. The couple of specimens I found 

 were vigorous and well developed. 



Distribution: Only found at Kjollefjord, very rare.
