one surface, slightly constricted at base and depressed at apex, having a 
very thick densely cellular wall, and containing a nucleus which does not 
nearly fill the cavity. Colour a pale red, fading to yellowish or dirty-white. 
Substance thin, membranous and soft. In drying, the frond adheres closely 
to paper.

This appears to be a well-marked species, not likely to be con- 
founded with any other, although in general outline it resembles 
some states of &. palmata. 'The capsule-bearing frond, from its 
profusely abundant and very prominent cystocarps, bears much 
resemblance to Gracilaria polycarpa, but it is an external resem- 
blance merely. Again, there is some similarity between the 
cystocarps of our plant and those of an Epymenia, especially in 
the very thick walls of the pericarp and the ample cavity. But 
here again the relation ends, and on the whole, so far as we 
know, our plant is best placed in Rhodymenia. 
I am not aware on what part of the east coast of Tasmania 
Mr. Gunn collected the few specimens which are all that I have 
yet seen of this species.
