It does not appear that any author has been acquainted with this species of z4diantum, except 
M. Desvaux, who, in a volume of the Berlin Magazine of. Natural History for 1811, has published 
it under the name of zdiantum obtusum, but without being aware of its native country. It was 
thus with much satisfaction that we received from the lamented Sir Ralph Woodford, governor of 
the Island of "Trinidad, specimens gathered by Mr. Lockhart in that fertile country. From one of 
these the figure here given was made. It is very distinct from any other described species of the - 
genus, and has rather the habit of some Zndsec than of z4dianta in general.
