Si 



defcription, fpecimen, and figure, that C. fracia, T. 14, is the fpecies here 

 intended. 



3<5. C. nipe/lris. T. 23. The fpecimen No. 28 of the Dillenian Herbarium, 

 to which Hudfon refers as his variety £ of this fpecies, is much injured, but I 

 have little doubt that it is C. dijfufa. T. 2t. 



37. C.fericea. In the Dillenian Herbarium there are two fpecimens under 

 the name of C. marina trichoides virgata feiicea, of which one is marked " ex 

 aquis dulcioribus," the other " e maritimis ;" and of thefe the former is a 

 trifling variety of C. glomerata. I have never feen C. glomerata with a fimilar 

 appearance to that of the latter, or having the branches fo much Elongated, but 

 from the look of the joints, difpofition of the ramuli, and place in which it was 

 gathered, it may probably be Dr. Roth's variety |S. marina of that fpecies. 

 According to the Flora Anglica, C. ftricca grows " in rupibus et faxis fub- 

 marinis 5" and I cannot help fufpccting that Hudfon confounded C. Icete virtus 

 with other plants under this name, but neither that fpecies, nor either of 

 Dillenius's fpecimens have the leaft affinity with C. httoralis, to which in the 

 Hijloria Mufcorum it is faid to be clofely allied, and I therefore doubt whether 

 C.fericea can be regarded as a fingle fpecies. 



38. C. glomerata. T. 13. 



39. C.fulva. I fufpect that C. repens, T. 18, is the plant here defigned, 

 but proof is wanting. 



40. C. nigrefeens. Following the generally received opinion among Botanifts, 

 I have in my fynopfis agreed with Dr. Smith in retaining the appellation of C. 

 nigrefcens to the plant fo called in Englifi Botany, though, in fo doing, I have 

 acted in oppofition to my own private opinion, and to the authority of Sir 

 Thomas Frankland, who communicated to me a fpecimen of C. urceolota under 

 that name. 



41. C.fufca. T. 95. 



42. C.fucoides. T. 75. 



43. C. villofa. T. 37.
