tion with Harvey's diagnosis. Cf. also the remarks under the 

 heading of Sargassum Kjdhnanianum in the present work. 



Sargassum serratifolimn Ag. has been doubtfully referred to 

 Sargassum tortile by J. Agaedh. He also added that Halochloa 

 macrantha Kütz. might be referred to the latter species. These 

 three plants, in my judgment, can scarcely be separated unless 

 one is supplied with a complete set of specimens of each. 



I shall not say anything about the opinion of O'Kl'NTZE^^ 

 who declares that the present plant belongs to Sargassum vulgare 

 and Sargassum medium.
