102 ART. 11'. — K. Y ENDO. 



Saryassum hemiphylloiäes Kütz. was suspected by J. Agardh 

 to be nearly related to Scwgassum chinense. He, however, left it 

 in doubt, as Kützing's figure had a regular dentation on the 

 outer margins of the leaves. This character as well as the round- 

 headed vesicles shown in tlie figure presents no objection to a 

 union of KUïzing'« plant with the present species.

Description of the species. A well grown plant measures 

 75-120 cm. in height, and is attached to the substratum by a small, 

 depressed, conical root. The primary stem is subterete and hardly 

 exceeds 1 inch in length, sending out several branches fascicu- 

 lately from the top. At an early stage ,of development these 

 branches are bud-like with numerous, thick, scale-like leaves
