 This planl bears a considerable resemblance in form to 

 "Rhodymenia Valmetta,9&A still more to the E.Jlabelli- 



of the Southern Ocean, bu1 the colour and the P 

 fication, so far as the latter is known, arc very different : 

 and I agree with my valued friend Mrs. Griffiths in re- 

 garding this as a species of Phyllophora, nearly related to 

 jP. Brodicei. 



201. Brodisei (Brodie's Phyllophora) ; Btem cylindrical, fili-

 ferous from their extremity ; tubercles sessile on the ti

 Mr. Brodie, after whom this species is named, was par- 

 ticularly attached to the study 01 the Algae, among wnich 

 lie made many interesting discoveries, the present among 

 the number, and during a long and active life enjoyed the 

 affectionate respect of a Large circle of scientific friends.

many others by Dr. Walker Arnott, the present owner of 



the Brodiaean Herbarium.
