Remark on the synonymy. Cystophyllum Lcpidium Harv. 

 aiitl Cystophyllum hypocarpa KÜTZ. are not well marked with 

 Gystop)hylluin gemuialum J. Ag. This circumstance has been 

 noted by former writers, who, however, mentioned the three 

 j)seudo-species separately. Setchell and Gardner^' united them 

 into one under the single species Cystophyllum geminatum J. Ag. 

 which is highly preferable. 



Ruprecht '■ says that Cystophylluvi Lepidium does not occur 

 in the north Pacific, and that the specimen in Mertex's her- 

 barium bearing that name and labelled " Insul. Kurile " seems 

 to have been collected at Saghalin Island. The specimens, 

 however, in our hands are from the southern Kuriles. In 

 Etorofu Island, where I collected the plant, it is especially 

 common along the northern side, often covering an extensive 

 area of rocks in the sublitoral region and not infrequently 

 occurrino; mixed with Fucus evanescens in the litoral region. 



Localities: Ivubetsu(!), Shana (h.ii. f.), Etorofu Isl. (Oka- 

 31URA). Uruppu Isl. (h. H. p.).
