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 caespetitium, 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 germination of mosses. I would particularly direct the attention of botanists to Oscillatoria muralis.
