Notes on Algae New to Japan, 

 Concluding Remark. 



By 

 Kichisaburo Yendo. 



The number of algae enumerated in the present Notes 

 count 1 78 in all, species, varieties and formae together. Among 

 them 106 are Rhodophyceae, 29 Phaophyceae, and 43 Chloro- 

 phyeea?. There are reasons to believe that the number of algae 

 still to be added to the Notes may amount to dozens. These 

 will be mostly the parasitic forms, as well as various species 

 of Ectocarpaceae and of the callithamnioids. It is a hope of the 

 present writer that he may be able to publish before long some 

 additional reports to the Notes. 



The floristic character of the marine algae of Japan and its 

 relationships to that of the adjacent regions have not been 

 satisfactorily persued. The first paper written on the subject 

 was by Okamik.v" in Japanese in the year 1892. Our knowledge 

 on the algal inhabitants of Japan has been much poorer at 

 that time than at present and his view can not be naturally 

 of an apprehensive one. Later on, the same author treated 

 on the same subject as the material has increased, but always in 

 Japanese. In 1901, I wrote a short note on the distribution 

 of the marine algae in Japan which appeared in the Year Book 

 of the Minnesota Seaside Station, " Postelsia," Vol. I. It is 

 understood that on the south-western coasts there are no less 

 number of the equatorial and the Australian species, and that
