2GC SEA MOSS^... 



This plant grows from one to three inches high. 

 It has a somewlial robust leading stem with several 

 stout primoT)' branches, liifTering in »V^I- respect from 

 C hyswiJes^ but the final branchlei^ .m.i ramuli are 

 extremely fine and delicate, and somewh.it long. 



A variety of this species, seirosprrmum^ diflkTs 

 from the t)'])ical fonn by being a triHe r and 



coarser, with the ultimate ramuli n< ndant or 



s<) long and silky. It lias, howe\'er, much the same 

 habit of growth, and with the aid of a good lens, 

 may Ixr determined without difficulty, when in fniit, 

 by the singular strings of l»eatl-like <rwircs which it 

 produces in the place of the comn ^exual tetra- 



six)rcs. 'ITic ictrasiwrcs of this genu.^ i;row externally 

 up the ultimate ramuli.
