but once, though I have repeatedly sought for them. They 
were origimally noticed many years ago by Sir W. J. Hooker, 
and figured from his drawing, in one of the supplementary plates 
of Dillwyn’s Conferve, and on the faith of that figure the plant 
has been erected into a genus by Bory,—a measure sanctioned 
by Endlicher,—and placed in the neighbourhood of Hctocarpus. 
Whatever the nature of these bodies may be, I think that this 
little plant can scarcely be removed from its congeners without 
violence; and certainly am unwillmg to admit a relationship to 
Eetocarpus. 'The spore-hke bodies may be of the nature of 
buds, or excrescences, and may possibly be afterwards changed 
into the tufted ramul, which are frequently found, as it were, 
bursting from the sides of the filament.
