an Atrichum) by Thomas P. James, Esq., there will doubt- 

 less yet be detected many other well-known European 

 species, not a few of which have already been collected in 

 British America by Drummond. 



The southern section has been even less carefully ex- 

 plored, and offers a promising field for future discoveries. 

 Among the recent accessions to our Flora from this quar- 

 ter are an Orthotrichum, a Fissidens, and several BruchicB 

 and FabronicB, gathered by H. W. Ravenel, Esq.; also 

 some fine Sphagna, an Anomodon, a Fontinalis, and a 

 Macromitrium, brought thence by our friend, the excellent 

 bryologist, M. Leo Lesquereux. 



No portion of our territory has contributed so little to 

 our Bryology and Hepaticology as the Florida peninsula, 

 which in this respect still remains almost a terra incog- 

 nita : its only known species, Pilotrichum cymbifolium, like 

 Meteorium pendulum from Western Louisiana (whence 

 novelties may also be expected), is thoroughly tropical in 

 all its characters, and gives promise of new and interesting 

 forms to reward future explorers.
