This is one of the many species of Conferva first brought to 
the notice of botanists in the excellent monograph of Dillwyn, 
where a correct figure is given of it. It appears to be generally 
diffused throughout the Atlantic, extending even within the 
tropics. It is always a more tufted plant than C. Melagonium, 
paler in colour, of scarcely half the diameter, and, though harsh, 
far less rigid and quite unable to support itself when removed 
from the water.
