In Mr. Turner's Herbarium there are bleached fpecimens of a light 

 draw color, gathered by Mrs. Griffith at Sidmouth, which differ fo much 

 from the common appearance of C. rubra, as to have induced both thefe 

 Botanifts to regard them as belonging to a feparate fpecies. They are 

 fcarcely two inches long, and comparatively thin : their fubftance is remark- 

 ably thick and cartilaginous, but the leading difference is in the joints, 

 each of which is marked in the center with a dark globular fpot, nearly 

 fimilar to thofe which may be often feen in C. polymorpba. The fructi- 

 fication confifts of feeds fcattered through the interior of the ultimate 

 ramuli, but thefe can by no means be confidered as an indication of fpe- 

 cific difference, fince they have been alfo obferved in many of the other 

 capfuliferous Conferva:. This remarkable appearance of C. rubra is re- 

 prefented at Plate F, magnified 5 and 3, from a fkctch with which Mr. 

 Hooker favored me.

Since the publication of this fpecies it has been found abundantly in 

 Bantry Bay, by Mil's Hutchins, and on the Dcvonfhire coaft by Mr. Griffiths 

 and Mifs Hill.
