stance cartilaginous and the plant often imperfectly adheres to 

 paper in drying. 



Hab. : On rocks, stones, shells, gravels, sticks etc. ; those on 



the rocks of open shore are smaller in forms and those growing 



in brackish water in sheltered places are often very long. Widely 

 distributed within the boundary of our country. 



Gracilaria flexuosa Holm, is found to be nothing but the 



J o 



present species by my stud)- on a specimen kept in the herbarium 

 of Tokyo Imperial Museum at Uyeno. It is not clearly men- 

 tioned as the duplicate of the specimen sent to Mr. Holmes 

 by Mr. Saida, but it bears the same number (no. 75) as 

 that of the specimen sent to him. The specimen was so badly 

 prepared as to have flexuose and alternate habit and from this 

 Mr. Holmes seems to have been mislead to rise it in a new 

 species. I hope any one who has the convenience to study 

 Holmes' specimen in question shall prove whether it is Gracilaria 

 confervoides or not.
