The fiift*Variety is found upon the coafl: of Norfolk, the fecond. 

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

 on the ifle of Portland. 



Mr. Hudfon, from obfcrving the branches at length terminating, 

 hi a dilated membrane, claffed the third variety with his Cera?ioides. 

 in his (iiv'iCion frofide plana aven/d. At the fame time the fourth' 

 variety was placed in his divifion foiiis diJihiBis; as, in good truth,, 

 that and all the other varieties, from, their having fo perfc£l a re- 

 femblance of petiolated leave', ought to have been. Perhaps, ftri£lly 

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

 hke the larger ones, in a dilated membrane. 



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

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

 mous leaves, and terminal membrane. 



In Gmelin's figure the tubercles are reprefented fefllle, 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 natura, to be the rudiments of leaves or membranes, and to 

 have no concern in the produ6lion of any thing relating to the 

 fru£lification. In all our fpecimens the fruflification is produced: 

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

 duncle.
