fmooth, and it is covered on both furfaces with nearly iiriifterfcf 

 tubercles, perforated at the top, and filled with feeds — Bcfides- 

 thefc, are oblervable on the recent plant numerous pencils of 

 fine hairs, which have been fuppofed by fo me authors to be the 

 {lamina, and by others the iryles ; but which are probably organs, 

 by which the plant receives nourishment ; the fame being obfer- 

 vablc on the Y.ferraius and fome other fpecies, in which the fruc- 

 tification is fituated very differently from what it is on this plant. 



We have quoted elongates of Linn., as well as loreus for this fpe- 

 cies, being convinced from a careful examination of the fpecimens- 

 in the herbarium, that they do not differ, and that the breaking 

 of the former, which is defcribed in Syjl. Vegei. as characteriftic of 

 the fpecies, is merely the effect of drying after having been fixed 

 to the paper. It is further to be obferved, that the fpecimen named 

 elongatus is mentioned as having been found in the Britiih feas as 

 well as loreus, and that no other than, the latter, and its above- 

 mentioned variety have ever been found fince on the Britiih coaft. 



The F. lor ens is figured in A8. Gall. 1772, part. 2. pi 3. f. 14. y. 

 where the fructification is magnified. It is the work of Meffrs. 

 Fougeroux de Bondaroy and Tillet.. They have examined the 

 marine plants very minutely, but they confound digiiatus and 

 hdbofus together, faying the ftipes is both flat and round. The 

 following remark upon the fructification occurs in their treatife : — 



* J'ai deffme une des ramifications de cette plante vue a la loupe; 

 4 Ton y decouvre de petits fucoirs que M. de Reaumur a deja re- 



* marques, et qui font les capfules des grains de ce fucus.* The 

 root is figured pi. 4. f. 18, 19. but the confufion. of F. digiiatus 

 and bulbo/us is rather an argument againft their accuracy as well as * 

 judgment. 



This fpecies is found abundantly on the rocks on the fouth-
