low-water mark to a depth of 10—15 fathoms, or probably 

 descending farther down. In the litoral zone I have only 

 seen it in rock-pools between half tide and low-water mark. 

 In mnch exposed localities f. genuina and £ grandifoUa are 

 vigorous and luxuriant. The former also grows in sheltered 

 places, or even in the interior of deep bays. I do not know 

 when the plant develop its reproductive organs. 



Distribution: Common and very abundant especially 



^ 



along the unsheltered part of the coast, but also pretty plen- 

 tiful in the interior of the deep fjords. The forms valida, 

 complanata and stenophylla only found at Berlevaag; f. gran- 

 difoUa at Berlevaag and Kiberg, bnt probably more common- 

 ly dispersed; f. ensifolia scattered and, as far as I know, rath- 

 er scarce.
