as they were gathered from a sandy bottom they were doubtless 

 free-floating examples; otherwise I only found them washed ashore, 

 and it appears as if the specimens found by other collectors were 

 also only such as had been cast ashore; thus, Lyngbye does not 

 enter into any details regarding its habitat. I am therefore not 

 prepared to say anything definite regarding its habitat around the 

 Færoes, but I believe it grows along fairly open sea-shores and 

 probably in the sublittoral zone, as it can only bear a short period 

 of desiccation without injury. 



I found it bearing assimilative hairs in June and July. 



It is hardly common along the coasts of the Færoes. Lyngbye 

 (1. c.) writes with reference to it: — »Habitat ad littora Færoensia haud 

 frequens, ut in sinn Qualboe Suderoe, et ad littns Molen prope Eide 

 Osteroe«. Rostrup eollected specimens of it on the east coast of 

 Stromo where it was also found by me, viz. near Thorshavn and Hvide- 

 næs. Again, Si ni mons observed it near Ejde (Ost.) and I near Kvalbo 

 (Syd.), i. e. in the same piaces where Lyngbye found it.

Found growing in the sublittoral zone down to a depth of 

 some 10 fathoms; it rarely occurs at greater depths and Kjellman's 

 statement (1. c.) that specimens were found near Spitzbergen down 

 to a depth of 150 fathoms must undoubtedly be due to detached 

 floating examples having been carried by the stream to deeper 

 waters. 



It grows by preference in the open sea but mav also be met 

 with in somewhat sheltered situations. It is generally found growing 

 attached to stones and rocky bottoms, but also occurs, though rarely, 

 as an epiphyte, especially on the stem of Laminaria. 



This is a very common species of the Færoese coasts, as was pointed 

 out by Lyngbye, who writes: -- »Ad insulas Færoenses copiose«.
