Some specimens from Strsender (Ost.) which I must regard as 
belonging to the typical form bore quantities of plurilocular as 
well as unilocular sporangia on the same plant, sometimes even 
intermixed on the same branch; but either one or the other kind 
greatly predominated on the same branch, and either exclusively 
unilocular or plurilocular sporangia were frequently met with. The 
unilocular sporangia often occurred in great abundance and were

placed quite close together so much so that they frequently came 
in contact with each other, being even closer than is shown in 
the accompanying figure (fig. 71, a). Such plants bore considerable 
resemblance to Ectocarpus pycnocarpus Rosenv. (Gronl. Havalg., 
p. 886). The unilocular sporangia were about 65 y long and about 
40 y broad, of about the same size, consequently, as reported by 
Rosenvinge, and two sporangia on the same cell is also here 
sometimes met with, and also a vegetative branch proceeding from 
beside the sporangium. The main filaments could attain to a 
thickness of up to 10 y. In fig. 71 is shown a portion of the plant 
bearing unilocular sporangia (a) as well as a branch bearing
