In no part of the vegetable fyftem, has the introduction of the 

 Linnsean Herbarium into England, and the free infpecYion of it 

 which the liberal pofTeilbr permits for the benefit of fcience, 

 been the means of detecting 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 hard'y have been, 

 credited by the Britifh botanift, that the plant defcribed by Mr. 

 Hudlbn and the other Enghiri authors by the name of Fit c us con- 

 catenates r was in reality the foeniculaceus of Linnaeus, than which 

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

 which we have received fpecimens from the Mediterranean exactly 

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

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

This fpecies is branched immediately from the root, and thefe 

 branches generally proceed throughout, but are each of them again 

 divided and fnbdivided, the fmaller branches having numerous 

 oval veficles, 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 branches,
