n& 9 ramofiffima — ictf«/dichoromi, apicibus necnon angulis ramifi- 

 cationum obtufis — Subjiantla membranacea, fiftulofa, extus tomen- 

 tofa feu potius velutina, fplendcns — Color viridis — Fruclificatio incog- 

 nita. 



The frond in this fpecies is (lightly comprefTed ; but as it ap- 

 proaches much nearer to a round than to a flattened form, it feems 

 to belong more properly to this divifion than to the preceding. 



The whole plant is membranaceous and hollow, covered with a 

 glofly velvet down, which fufficiently diftinguifh.es it from all with 

 which it might be fuppofed to have any affinity. From thefe cir* 

 cumftances, and from there never having been yet any fructifica- 

 tion difcovered, it is very doubtful whether it may not belong to the 

 genus Ulva ; but till this can be afcertained, we have thought it 

 mod proper to continue it in the fituation where it has been hither- 

 to arranged. 



The root is merely an expanfion of the frond, by which it adheres 

 to the rocks. — It is of a grafs green colour, much branched, the 

 branches dichotomoufly divided with obtufe angles ; the terminat- 

 ing forks 2, 3 or 4, varying in length from a line to half an inch, 

 more or lefs blunt, with the angles very much rounded. The plant 

 retains water like a fponge, and is as eafily preffed dry ; a circum- 

 ftance noted in Ray's Synopjis. 



This fpecies is erroneouily referred in the Flora Anglica, and in 



Withering's Bot.Arrang. to elongatus Linn, which we believe not at all 



to differ from loreus, and to which it has not the fmalleft affinity. 



That it is the plant figured in Morifon, the Spongia dkhotomos tereti- 

 folia viridis of R+Syn. cannot be doubted; nor do we hefitate to refer 



to this the Spongia dichotomos compreffa ex viridi-fplendemoi Dillenius/?.
