iv 
an Atrichum) by Tuomas 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 Drummonp. 
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 Bruchie 
and Fabronia, gathered by H. W. Ravensr, Esq.; also 
some fine Sphagna, an Anomodon, a Fontinalis, and a 
Macromitrium, brought thence by our friend, the excellent 
bryologist, M. Lro Lesquerevx. 
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.
