The narrow Baltic form (fig. 447, Plate VII fig. 7) is much feebler and less 
branched than the typical form and thereby rather characteristic. It is, however, 
connected with the typical form by transitional forms. It may be named f. baltica. 
Some of the specimens of this form were loose on the bottom, especially those found 
north of Moen. 
The vegetative growth begins in winter and ceases in summer. Antheridia were 
met with in October and November, cystocarps and tetrasporangia in January to 
April. The species has been found growing on stones and on various Algæ (Fur- 
cellaria, Fucus serratus, Halidrys, Ahnfeltia, Laminaria etc.). It has been met with 
from low-water mark to 27 meters’ depth.
