Chiefly a litoral alga, occupying a broad border mostly 

 in the middle part of the zone. In the inner part of some 

 of the greater bays, for inst. Jarfjord, it descends a little 

 below low-water mark. The plant is vigoronsly developed, 

 attaining a length of 1.5 m. and more. It bears plenty of 

 reeeptaeles in July. The spores are generally ripe in the 

 middle of the month, Almost all the speciraens I have seen 

 in Augnst, even in the beginning of the month, were sterile. 



Bistrihution: Common and in great abundanee everywhere.
