Hab. on submerged rocks, Mendocino City, Sol. 



By the ventricose or enlarged duplicature of its leaves, this species resembles 

 F. rufulus, Brch. & Schp. In our species the leaves are more obtuse, and generally 

 entirely surrounded by a thick margin like those of F. rivularis of the same authors. 

 It is only in the upper leaves of new branches that the leaves appear similar to those 

 of F. rufulus. The division of the stems is generally from near the base and dichoto- 

 mous, sometimes the primary divisions being divided again near the top in short 

 branches. The axils of all the leaves bear tufts of radicles. The specimens sent to me 

 had but one capsule, already deoperculate.
