I have collected only one specimen which I identifv with 

 here mentioned species. J. Agakdii relates its affinity with 

 Sp. variabile. The present plant, however, appears to me to 

 be well distinguished from the latter by having roundish sini 

 and cuneately dilated segments. The original specimen in the 

 Agardhian Herbarium has the terminal parts of the voungei- 

 segments irregularly palmatch' divided with wide sini. This 

 character is also well manifested in my specimen and may l)c 

 mentioned as a good distinction to separate it from Sp. variabile. 



J. Agardh defines the species as having the outer margins 

 of the segments entire and the inner, provided with minor 

 lobes. This is also the case with the Japanese form. It may 

 be interpreted to be due to the fact that the palmately divided 

 upper segments are not in equal degree of development, 3^oung 

 and short segments being frequenth' found in the inner margin 

 of a larger segment. But in the original as well as in raj' 

 specimen it is not seldom to find such minor segments in the 

 outer margins. 



As this plant has never been enunciated with illustration, 

 the sketch here accompanied may be in some use to those who 

 are not familiar with the authentic specimen.

Although I have specimens from but one locality', there are 

 reasons to assume that this species may have a wide dis- 

 tribution on our coast.
