The substance in the lower part of the frond is rather rigid, somewhat horny 
when dry; in the upper part it is flaccid and soft, but cartilaginous. In 
drying, all but the bases of the old branches adhere pretty closely to paper. 
From G. confervoides, to some varieties of which this seems 
to be nearly related, our plant differs in its softer and much 
more flaccid substance, and especially in the more regularly di- 
chotomous ramification and the circumscribed or fastigiate ge- 
neral outline. I have received many West Australian specimens, 
all of them preserving the same general aspect. The only Aus- 
tralian Alga with which it is likely to be confounded is Dicranema 
filiforme, Sond., a native also of Fremantle, and closely resem- 
bling it in size and ramification, but differmg in structure and 
fruit.
