Ruprecht 's description of this species is very explicit, not 

 only of the habit and habitat, but also of the microscopic struc- 

 ture, so that there can be no doubt as to the identity of the two 

 sets of plants. From Ruprecht 's account it seems to be abun- 

 dant in the Ochotsk Sea. While the extreme forms of these two 

 species on Cystophyllum are amply distinct, there are narrower 

 forms of G. Californica, approaching to some extent the more 

 robust G. Cystoseirce, so that it does not seem impossible that 

 the latter may be only a pronounced geographical variety of 

 the former.
