clufters on fhort lateral pedicles, but I* have never been fo fortunate as to meet 

 with it. Col. Velley adds that it is rarely found. 



The only two fpecies which can poflibly be confounded with C. fetacea are 

 C. corallina and C. ftridta; from the former it differs in its more flender 

 filaments and cylindrical joints; while its much lefs numerous branches, far 

 longer joints, veinlefs filaments, fmaller fize, and brighter color, will readily 

 djftinguifh it from the latter. 



When this plant is placed in frefh water, a fcarlet liquor oozes from the 

 joints; in drying it adheres to both glafs and paper. The colour is remarkably 

 fugitive; it changes from expofure to the air to a dirty orange.

* Since the above was written, Mr. W. J. Hooker has been fo kind as to favor me with a fkcuk 

 of the fruit of this plant from a fpecimen in my friend D. Turner's collection, communicated to 

 him by Mr. Templeton from the North of Ireland. There is fomething fo extraordinary and 

 anomalous in the fructification, that 1 am unable to compare it with that of any other fubmerfed 

 alga; the feeds are borne as Col. Velley defcribes them, but do not appear to be contained in a 

 tubercle, and have a pellucid limbus more ftriking than in any fucus I am acquainted with. Mr. H. 

 Davies has fuggc^ed that this plant, not C. rubra, as quoted by Hudfon, is the true C. flofculofa of 

 Ellis.
