Notes on Algae New to Japan, 



By 



K. Yendo. 



Every time when we try a collection of marine algae at our 

 sea-shores we have to make acquaintance with one or two 

 strangers. Examinations on them prove some to be undoubtedly 

 new to science and some already described but not reckoned to 

 Japan. The number of the species yearly added to the list of 

 marine flora of Japan by the native as well as by the foreign 

 botanists is often remarkable. Yet there are not a few known 

 species that have escaped from the informations hitherto pub- 

 lished. The present short paper is intended to comprise such 

 members, ascertained by myself to occur within our boundary. 

 As for the new species and genera, another paper shall be pre- 

 pared in future.
