Description of the species. The fronds are apparently niulti- 

 cipital, arising from a rugose knotty prostrate stump. Morphologi- 

 cally speaking, the stump, as in Coecophora Langsdorfii, is a 

 dwarfed stem, and the erect stems upon it correspond to the 

 principal branches of Cystophylluiii and Saryassum. The stems 

 are cylindrical, 20-30 cm. high, more or less abruptly thickened 

 at the very base, with short stunted ramules subregularly spirally 

 disposed above: angle of divergence ca. -^. 



Ramules are beset with filiform elongated leaves at the base 

 and with subulate scale-like leaves above, in the same disposi- 

 tion as the ramules on a stem. The filiform leaves divide 

 dichotomously once or twice with wide axils, with a few elevated 

 cryptostomata on the surface; the base of a leaf is generally 

 abruptly expanded and often stipule-like. The scale-like ones 

 are obcuneate, broadened downward, concave inside, and longi- 

 tudinally ridged outside (fig. 12).
