Both Mr. Drummond, of Cork, and Dr. Greville 

 agree in considering this heretofore species nothing 

 more than the radicals of Polytrichum aloides ; and, 

 that a Conferva, scarcely to be distinguished from it 

 is so of Bryum c&spetituim, careful observation has 

 convinced me. It is by no means improbable that 

 other supposed Conferva:, upon close investigation, 

 may turn out to be no more than the first germina- 

 tion of mosses. I would particularly direct the at- 

 tention of botanists to Uscillutoria muralis.
