In no part of the vegetable fyftcm, has the introdiidion of the- 

 Linnaean Herbarium into England, and the free infpe>5lion of it 

 which the liberal poffeflbr permits for the benefit of fcience, 

 been the means of detefting more errors than in the genus Fucus\ 

 and in no fpecies of that genus is this more confpicuous than in 

 the prefent. Without this authority, it would hardly have been 

 credited by the Britifli botanift, that the plant defcribed by Mr^ 

 Hudfon and the other Englifli authors by the name o{ Fucus con- 

 catenatus, wzs in reality the fceniculaceus of Linnseus, than which 

 nothing is more certain ; and that the concatenatus of Linnaeus, of 

 which we have received fpecimens from the Mediterranean exaitly 

 corrcfponding with that in the Herbarium, is a very different plant, 

 and has not hitherto, as we believe, been found on the Britifh 

 coaft. 



This fpecies is branched immediately from the root, and thefe 

 branches generally proceed throughout, but are each of them again 

 divided and fubdivided, the fmaller branches having numerous 

 oval veficlcs, nearly contiguous to each other, refembling a chain, 

 and terminated by a multipartite leaf, with fubulate fegments, 

 which, when in fructification, are furrounded by minute tubercles. 

 The veficles are not always confined to the terminating brancheSj
