Notes on Japanese Plants, XVII. 7 

Hab. Boshu, Sagami, Shima, &c. On rocks near Weel water mark. 
Formerly 1 considered the present plant as a distinct species, but on studying various forms of speci- 
mens from different parts of the country, I came to the conclusion that the present plant is a variety of 
Grateloupia affinis, differing from the type only in size, breadth, and thickness of the frond. As this form 
grows in the warmer parts of the Pacific coast, I think its difference from the type must be a result of 
the influence of the habitat. 
Pl. V. Fig. VI. VII. Two forms of G. affinis var, lata (nat. size)—VI. With cystocarps on the apical 
portion of frond. 一 -VIII. Portion of cross-section of frond (x 230).—IX. Portion of cross-section of frond 
with tetraspores (x 230).—X. Same showing the anastomosing texture surrounding the simple nucleus which 
has been removed.
