No plant can well be fuppofed to vary more than this. If we 

 view the extremities of its variation, the one will be found with a 

 broad dilated membranaceous frond — the other with a narrow 

 linear cartilaginous compreffed one. Neverthelefs the tranfition 

 from the one to the other is fo gradual, that it is not eafy to be 

 perceived where any difference takes place — 



Ufque adeb quod tangit idem eji — 



It comes in competition with none of the Fuci which are arranged 

 in this order, except the young fpecimens of F. rubens; but the 

 flighteft attention will diftinguilh it from this. In the firft place, 

 this plant is never in any degree proliferous ; and in the next, its 

 fructification is fmooth tubercles imbedded almoft or entirely in the 

 fubftance of the frond, not what Mr. Lightfoot calls warts, which 

 when magnified appear to be the curled rudiments of young leaves.
