ties it usually assumes forms more or less differing from the 

 typical one. The proper time for the development of repro- 

 ductive organs at East-Finmarken seems not to be the sum- 

 mer months. In July and August I have taken a few spe- 

 cimens with sporocarps and in the same months others with 

 tetraspores. At Nordland it has been found with sporocarps 

 in great numbers in March and tetraspores in February, but 

 never in the summer months. 



Distribution: Common and rather plentiful all along 

 the coast, rather scarce in the inner part of the bays.

It was quite unexpected to meet with large and very 

 luxuriant individuals of this species in the eastern part of 

 the district. Two times (in 1887 and 1889) I found washed 

 ashore at Vardo and attached to the stem of Laminariahy- 

 perborea a few specimens, one of which was about 70 cm. 

 long, with the leaf-shaped branches reaching 28 cm. in length 

 by 4 — 9 cm. in breadth. The specimens were quite fresh, 

 the host plant likewise, and cast on shore after a heavy gale 

 the night before I found it. (The locality was investigated
