The most common form of this species growa generally 



I 



scattered, often with isolated, small individuals, 0.5 — 1 cm. 

 in height, as to the shape and position of the branches most 



nearly agreeing with fig. 3—4 on pl. 36 B in Harv. Ner. 



Bor. Am. However the cells of the mainaxis andof thelong 

 branches are shorter than in American specimons according 

 to Harvey. The length does not exceed 4 times the dia- 

 meter, generally 2 — 3. I have seldom seen specimens with 

 as patent and rather blunt branches as the form fignred by 

 K j ell m a n 1. c. On the ii-on buoy at Berlevaag mentioned 

 under A, floccosum, I met with rather luxuriant individuals 

 reaching a height of 5 cm. They resemble H a r v e y's fig. 

 1 1. c., or sometimes more densely branched, and almost 

 fuUy coincide with American specimens determincd by F a r- 

 low, only smaller and a little darker. The cells of the main 

 axis and partly of the long branches are up to 6 times lon- 

 ger than the diameter. These specimens I have referred to 

 the typical form, and most af the above mentioned smaller 

 ones with short cells and somewhat patent branches I have

referred to f. nmvegica. The latter I think to be only a
