multipartitis obtufis terminals — Fruclifcatia, tubercula minuta in 

 foliolis terminalibus, et in ipfis vcliculis feminitera,--G?/sr recentis 

 plantse olivaceus, ficcatse niger. 



This fpecies has been involved in great doubt and obfeurity: but 

 the inflection of the Linnaean Herbarium, in which the actual Spe- 

 cimen gathered by Leofltng on the Britifh coaft: is prefcrved, has 

 entirely removed the difficulty. 



The fpecific character and defcription given above weve made 

 from a young and vigorous fpecimen brought from the Mediter- 

 ranean, in which all the leaves were whole, and had apparently all 

 their mod minute ramifications. That in the Lmnrcean collection, 

 and from which Linnseus himfelf formed his fpecific character, is 

 a much older one, in which the lower linear lei- es and the fine 

 of the upper ones are broken off; as is the cafe with iiioit lea plants 

 when long expofed to the action of the waves. 



In the fecond MantifTa this fpecies is 1-1 erred to Fucus catcnfis^ 

 Gm. 157. /. 17. f. i.; but certainly erroneouih, as is evident from the 

 Linnaean fpecimen before mentioned, than which nothing is more 

 unlike caperfis. 



It differs from barbatus in having veficles, and in fome other par- 

 ticulars which are pointed out under that fpecies. It agrees with 

 fam'cu/ocetts, in having frequently one or more leaves growing from 

 the fides of the veficles ; but differs in having thefe leaves constantly 

 obtufely terminated, whilft thofe of faniculaceus are always fubulate. 

 It differs alio from the latter in the fhape of the lower leaves and 

 in colour. 



We have never met with this fpecies in a growing ftate ; but have 

 defci ibed it as an Engliih plant on the authority of LeotYmg's fpe- 

 cimen in the Linnaean Herbarium, and from having feen it among
