majority of botanists, that the several forms called #. erecta, LP. 
clathrata, md FL. ramulosa are but different states of one species ; 
and may now add that #. Linkiana, of Greville, and /. Hop- 
kirkii, Me’Calla, are, in my judgment, equally doubtful. Still, 
as the plants which have received these names present very diffe- 
rent aspects, and from their size cannot be presented in the same 
plate, it is my intention to give separate figures and descriptions 
of all of them, and then to leave it to the judgment of botanists 
whether to adopt the notion of one protean species, or of many 
less variable, but still axastomosing species, or, more properly, 
races. 
F. erecta is one of the most beautiful forms, particularly when 
dredged in deeper water than comes within the usual tide range. 
Such are the specimens represented in our plate, which were 
dredged in Torbay. In these the ramul are even more feathery 
than the figure exhibits.
