Plant at first erect and more regularly dichotomous, 10-20 err. 

 high, afterward becoming entangled into a very large mass by- 

 twisting on the branches of Sargassum with thickened and crooked 

 portions. Frond filiform, cylindrical, ca. imm thick in older specimens, 

 irregularly branched in dichotomous manner. Branches patent, more 

 or less furnished with lateral, simple or mostly many-times forked 

 branchlets which are often disposed in subsecund manner in younger 

 fronds. Terminal portion of branches of every order more or less 

 forcipated, especially so in younger fronds, but when the plant grows 

 in age lesser branches fall off and the frond becomes naked. Also, 

 terminal portion of main branches swells up beneath the apex in 

 sickle-shape, after the manner of Hypnea muscifonuis and in younger 

 fronds those swollen portions carry forked ramuli on the side and 

 apex. By these crooked portions, the plant becomes entangled to 

 each other and twisted on the branches of Sargassiim. 



Frond immersedly articulated and thickly corticated, the cortica- 

 tion becoming more and more thick in older portions. Length of 

 articulations suba equal to or one arid half times as long as broad. 

 Cortical layer consisting of two layers ; the inner, of more or les s
