THIS plant, which in my opinion has a claim to be confidered one of the moft 

 beautiful and interefting of its tribe, was firft made known to the botanical world 

 by Muller, who gave a chara&eriftic figure of it in the Flora Danica, as above 

 quoted : it was afterwards found by Dr. Roth in the Dukedom of Bremen, and 

 was laft fpring added to the Britifh Flora by my friend Dawfon Turner, who de- 

 tected it growing in fhallow pools on Lound Heath, near Yarmouth ; fince which 

 time we have together met with it in odier places on die Northern part of Suffolk. 

 What moft ftrikingly diftinguifhes it at firft fight is, its flaccid appearance rather 

 refembling that of the narrow varieties of Ulva compreffa, and the feemingly great 

 fize of its filaments, arifing from their cohefion; by which, and their mode of 

 growth, which is loofely entangled, the naked eye may diftinguifh it from C. nitida, 

 wherewith, when magnified, it has a Angularly ftrong refemblance ; lb much fo, that 

 it may be doubted whether it is more than a variety of that plant: it agrees with it 

 in fize, in the general length of its joints, though I have not obferved them fo vari- 

 able in C. jugalis as in that fpecies, and in the fpiral difpofition of its feeds ; but 

 differs in the latter collapfing from age into oval, or fometimes globular maffes, and 

 alfo in the connecting proceffes which form its moft ftriking character. Thefe 

 are thrown out by many of the joints, and are extremely fhort tubes, by means 

 whereof moft of the filaments attach themfelves to each other, and thereby re- 

 ceive a ladder-like appearance, whence Dr. Roth derived the excellent name of 

 fcalaris ■, which, however, as the plant was previoufly known by the equally appli-
