CONFERVA CASTANEA. 



C. filamentis repentibus ramofis fub-bipinnatis imbricatis iraplexis, 

 pinnis pinnulifque alternis divaricatis, articulis longis. 



On hedge banks in a lane on a high hill between the Gower and Lougher 

 Roads, about four miles from Swanfea. 



THIS Angular fpecies is found in great abundance on the fhady fide of a lane 

 near Swanfea, and I am not aware of its having been elfewhere met with. It 

 covers fticks, ftones, and earth, forming loofe patches of a brown-chefimt color. 

 The Item is creeping, and throws off feveral bipinnated decumbent branches, 

 about a quarter or half an inch in length, which moftly grow over and become 

 entangled with each other; the pinme and pinnulx are regularly alternate, 

 variously curved, and iffue at or nearly at right angles with the ftem and branches. 

 The diflepiments are almoft black : in the principal branches the joints are very 

 long, but they gradually become fhorter towards the ends of the ramuu No 

 fructification has been difcovered. 



In drying, the joints alternately collapfe, fo as to give the plant a fingularly 

 beaded appearance ; it adheres but Hightly to either giafs or paper. 



A. C. caftanea, natural fize. 



B. Ditto magnified 3.
