fmooth, and it Is covered on both furfaces with nearly immerfed? 

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

 thefe, are obfervable on the recent plant numerous pencils of 

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

 ftamina, and by others the ftyles; but which are probably organs,. 

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

 vable on the Y..feryaim and fome other fpecies, in which the fruc- 

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



We have quoted e/o«^/?/!^j 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 Syji. Veget. as- charafteriftic of 

 the fpecies, is merely the effe6t 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 BritilTi feas as 

 well as lo7-euSt and that no other than the latter and its above- 

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



The F. loreus is figured in J^. Gall. 1772. /^r/. 2. //. 3. f. 14. y. 

 where the fru£lification is magnified. It is the work of Meffrs.. 

 Fougeroux de Bondaroy and Tillet. They have examined the 

 marine plants very minutely, but they confound digitatus and 

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

 following remark upon the frudification occurs in their treatife : — 



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



* Ton y decouvre de petits fu9oirs 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. digitatus 

 and bulbofus is rather an argument againft their accuracy as well as 

 judgment. 



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



weflern
