(T. Fertile thallu.s. 



Picked out of a sample of Carrageen from Hamburg, 

 1871. (Ilanbury remarks, in pencil, that this 

 specimen more nearly resembles some forms of 

 G. acirularis, Lamx. It is, however, taller than that 

 plant, and more robust, although more sparingly 

 branched than Devonshire and Cornish specimens of 

 G. jnatillata, Stackh. It probably was of MediteiTanean 

 growth, this sparingly branched form being not 

 uncommon in that sea.)
