The main part of the specimens belongs to the typical 

 form. The breadth of the frond varies considerably. Multipartite 

 specimens with narrow lobes somewhat reminding of f. sarniensis 

 were found in Tasiusak. Many of the specimens have small 

 prolifications especially in the older parts of the frond. A few 

 fragments from Smalsund seem most probably to belong to 

 f. proliféra. The length of the frond varies from 5 to 46 cm. 

 The species was gathered in May — August, and with tetraspores 

 in May — July; in a depth of 3 — 30 fathoms.

The specimens I have had for examination belong to 

 f. robusta and f. rmiiosci] their length varies from 10 — 30 cm. 

 In specimens gathered in iMay young shoots were abundant. 

 The species was collected in a depth of up to 19 fathoms in 

 May— September. Specimens with tetraspores date from June, 

 July and September. The species seems to be common.
