My specimens fully agree with Kutzing's Tab. Phyc. XIII, 

 Taf. 4, fig. I, except that the number of involucre is mostly 

 5—6. In the sterile state the species is difficult to separate from 

 Ceramium rubrum as has been pointed out by Kylin. In the 

 Agardhian Herbarium there are specimens under C. rubrum 

 pedicellatum treated separated from those under C. pedicellatum. 

 My specimens coincide with the latter. Leaving aside the ques- 

 tion whether it should be regarded as a mere form of C. rubr- 

 um or as an independent species, I have but to mention the 

 occurrence of a form exactly agreeing with the above named 

 plant within our boundary. 



Locality. Rebut) Island(!). 



Distribution. North Atlantic, both European and American 

 side ; ? Coast of Chili.
