The typical form is litoral, growing epiphytic on oth- 

 er algse, as Polyides rotundus, Cystoclonium purpurascens, 

 Ceramium rubrum, Corall. officinalis and Chcetopt. plumosa. The 

 form uncialis occurs in rock-pools between tides and in the 

 uppermost part of the sublitora] zone. The plant has been 

 collected with zoospores in development in the beginning of 

 August, At "West-Finmarken it has been taken with such 

 organs at the end of May, and in August and September. 



Distribution: The typical form found at Mehavn, Syl- 

 tefjord and Kjelmo, rather scarce; f. uncialis at Lebesby, 

 rather scarce, and at Kjelmo in Sydvaranger, local but 

 pretty plentiful.

 know yet whether constant,
