cable term of jugalis, I have declined adopting. In this refpe£t the prefent fpe- 

 cies approaches the nature of C. genuflexa ; but the yellower colour, fmaller fize, 

 and broken appearance of that fpecies, are fufficient for the naked eye; and when 

 magnified, its far different joints and mode of growth immediately diftinguifh it. 

 Long filaments are often found wholly unconnected with the reft, and fometimes 

 the uniting proceffes iffue only from one or two joints. I feel myfelf perfectly 

 unqualified to offer the flighted conjecture on the purpofes which the wifdom of 

 Providence has defigned to anfwer by this fingular union of the joints. Citizens 

 Charles and Romain Coquebert, in a paper they communicated to the Philomatic 

 Society of Paris, fuppofe that it is fubfervient to the fructification, ftating it to be 

 ' the firfl inftance in the vegetable kingdom of a reproduction abfolutely analogous 

 to that we find in animals ;'* not only however may we obferve granules in every 

 refpect. fimilar in thofe joints which remain unconnected, but alfoin the filaments 

 which fometimes occur, in which not even the rudiment of a fingle connecting 

 procefs is difcernible. There is much curious matter concerning this Conferva 

 recorded in Dr. Roth's Catalefta Botanica, which I cannot but regret that the 

 limits of my prefent undertaking prevent my inferting ; I muft therefore refer my 

 readers to that work for farther information.
