Hab. on submerged rocks, Mendocino City, Bol. 
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 #. revularis 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.
