 Champia bifida Okam. nov. Sp. 



RHODYMENIACE/E. 



Nom. Jap. : Hira-watstinagi-sd. 



Diagii. ； Fronds perhaps decumbent, loosely intricated by 

 coalescing to each other, compressed, throughly articulated, usually 

 2-3 times distichously pinnate, with branches alternate and some- 

 times verticillate, patent, often subdichotomous above. Branches 

 narrowed toward bases, acute or bifid at apices, with joints 

 scarcely or slightly constricted and one-third or one-fourth long 

 as broad. Telvasporangia forming a dense orderless aggregation 

 between joints. Cystocarps scattered, sessile and ovoid with a 

 promint carpostome. 



Hab, Enoshima and Misaki (Sagami). Fruits — late in Spring. 



Decrip. •• Plants are loosely intricated with branches coalesc- 

 ing to each other by the formation of short root-like processes, 

 and may perhaps become decumbent by adhering to substratum 

 in the similar way, as this alga is only found washed ashore, and 

 whenever we cellect it, we can not obtain a perfect plant with 

 root, though the lower portion of frond is found to taper into 

 subcylindrical stem. Frond is compressed, usually branched 

 distichously in 2-3 times pinnate manner, attaining the hight 

 of 8-10 cm. in full grown plant. Branches are opposite or 

 alternate, often here and there dichotomous and sometimes 

 furnished with verticillate segments which arise from sides and 

 surfaces. 丁 he breadth of branches measures 2-7 mm., usually
