Stephani. No specimens of Bryopteris occur in the Puerto Rico =” 
collections studied by the writer. B. filicina has a wide distri- 
bution in tropical America. Among other West Indian islands tt 
has been collected on Jamaica, the type locality, Szar?z, Under- is 
wood, and on Guadeloupe, Husnot, From the mainland the fol- 
lowing stations may be quoted: Mexico, Miguel, Leibold, Lieb- 
mann; Costa Rica, Maxon; Colombia, Moritz, Lindig, Karst", 
Brazil, G. A. Lindberg. The species has also been reported from 
Tahiti by Reichardt, the specimens having been collected by the 
Novara Expedition. Stephani confirms Reichardt’s determination 
but suspects a mistake in the label. In all probability, therefore, 
B, filicina is confined to America. 
It is evident that the present species was understood by the 
older writers and probably by Swartz himself in a much broader 
sense than is indicated above. /ungermannia filicina was origin- 
ally described from sterile specimens, and it is by no means Ce 
tain that these would be considered sufficient at the present time 
for a positive determination. In Stephani’s opinion the Swartzian
