CONFERVA TORTUOSA. 



C. filamentis fimplicibus rigidiufculis implicatis tenuibus; diffepimentis 

 pellucidis ; articulis cylindraceis longiufculis. 



In Salt Pools by the River Yarc near Yarmouth, and on Rocks in the Sea about 

 Swansea. 



THE prefent plant fo nearly refembles C. capillaris in miniature, and fo well 

 agrees with the moft linking chancers of that ifpecies, that although it always 

 appeared to me to be diftinft, I hefitated on publifhing it as fuch till this opinion 

 was confirmed by that of my friend Mr. Turner, and by Dr. Roth, and Profeffor 

 Mertens. I firft found it in a Pool by the banks of the Yare, where C. capillaris 

 alfo grew, and fince on the rocks, and among the rejeftamenta of the Sea at 

 Swanfea. The filaments are as fine as the hair of the human head : their growth 

 is curled and entangled as in C. capillaris, but not brittle or fo rigid as in that 

 fpecies : it differs alfo in the joints which are nearly twice as long 5 nor have I 

 ever obferved the fwelling of the dilTepiments already mentioned in the defcription 

 of that plant. 



When taken out of the water and expofed to air it becomes flaccid, and adheres 

 but nightly to either glafs or paper. 



A. C. tortuofa, natural fize. 



B. Ditto magnified 1.
