MY friend D. Turner has juftly remarked to me that " it may be confidered 

 a ftriking inftance, how little the genus Conferva has been attended to by botanifts, 

 that above twenty years age, Mr. Wigg gathered the prefent fpecies at Yarmouth, 

 and preferved fpecimens of it in his Herbarium, which was fo often vifited ; but 

 that till Mr. Sowerby found it there in 1797, and I, on fending a plant of it to 

 Dr. Roth, was informed of its being his Ceramium rofeum, no author of this 

 country ever noticed it." That fuch has been the cafe with many other fpecies, 

 I have already had occafion to mention in this work, and is by no means a matter 

 of aftonifhment, but the prefent confidered as to its beauty, can hardly fail of 

 attracting the mod indifferent obferver, and regarded as to its habit and mode of 

 growth is fo different from all the reft, that no botanift could ever confound it 

 with any common fpecies. The root of C. rofea is a fmall expanded difk, which 

 gives rife to feveral Items, from one and a half to three inches in length, pinnated 

 from their bafe with numerous alternate branches, which are again repeatedly 

 fubdivided in the fame manner, fo that as they approach the fummits, they have 

 a very cluftered appearance ; in their thickeft parts they are nearly as fine as the 

 hair of the human head, and fo extremely fine towards their apices, as to be 

 fcarcely vifible. From the great tenuity of the moots the fubftance of the whole 

 is peculiarly flaccid, on which account it is difficult to expand it properly, but the
