The nrft variety is found upon the coaft of Norfolk, the fecond. 

 and third are very general, the fourth has been gathered by us only 

 on the hie of Portland. 



Mr. Hudfon, from obferving the branches at length terminating 

 in a dilated membrane, daffed the third variety with his Ceranoidei 

 in his dividon fronde plana avenid. At the fame time the fourth 

 variety was placed in his divifion foliis diji'mclis ; as, in good truth, 

 that and all the other varieties, from their having fo perfect a re- 

 femblance of petiolated leaves, ought to have been. Perhaps, ltrictly 

 fpeaking, thefe petiolated leaves are only young branches, ending,, 

 like the larger ones, in a dilated membrane. 



There is no danger of its being miftaken for any other Fucus m 

 this divifion, being kept perfectly diftinct by its nervelefs dichoto- 

 mous leaves, and terminal membrane. 



In Gmelin's figure the tubercles are reprefented fefiile, in -our 

 fpecimens they are all pedunculated ; from the narrownefs of the 

 frond, that as well as Morifon's figure is more applicable to our 

 third variety than the firft. The fyn. of Morifon quoted by 

 Gmelin ought to be excluded. Whoever will take the trouble to 

 confult Morifon, will immediately find that he is fpeaking of a plant 

 of an entirely different order. 



The cilia on the edges of the fourth variety appear to be a fort 

 of lufus nature, to be the rudiments of leaves or membranes, and to 

 have no concern in the production of any thing relating to the 

 fructification. In all our fpecimens the fructification is produced 

 on the branches, and is always fupported by a very fhort pe- 

 duncle.
