224 Dr. GooDENOUGH and Mr. WooDWARD'i Obfervations on 



bricata — Suhjlaniia cartilaglnca rigida — Co/or recentis plantae fiifcef- 

 cens, ficcata: nigei" — Fructlficailo incognita. 



This fpecies, which was unknown to any of our Engliih authors 

 as of Britilh growth, is one of thofe in which the hmits of the ge- 

 nera Fucus and Conferva too nearly approach each other; in confe- 

 quence of which it has been confidered by the autlior oi Fl. Dan. 

 as a Conferva, thoQgh placed by Linnaeus in the genus Fucus. 



The frond, of which three or four generally arife from the fame 

 bafc, is about fix or eight inches high, either fimple, or throwing 

 out a few Ihort branches, which are rarely again divided. The 

 lower part, for about the fpace of an inch, is always naked; but the 

 whole of the remainder, to the fummit, is clofely imbricated with 

 Ihort fubulate branches, either fimple or once divided, and termi- 

 nating fomewhat obtufely. Thefe ramuli have frequently, but not 

 conftantly, a fomewhat jointed appearance, which has occafioned 

 its being confidered by Oeder as belonging to the genus Conferva. 

 As neverthelefs the ftem is perfcdtly free from this appearance, and 

 the rough and fquarrofe habit of the plant accords better with the 

 Fuel, and as it approaches confiderably in habit and character to 

 the Fucus pinafroides, which has alfo fome of its extreme ramuli 

 with a jointed appearance, we have thought it moft proper to fol- 

 low the authority of Linnaeus, and arrange it as a. Fucus. 



The fru6lification has not yet been difcovered, but will probably 

 be found analogous to that of Fucus plnaflroides^ next in order to 

 which we have placed it. 



It has been found amongft other reje6lamenta on the beach at 

 Yarmouth in Norfolk.
