It is singular that this very striking species of Fern should so long have remained unnoticed in 
the much frequented island of Jamaica; and have been first brought to the knowledge of botanists 
by Humboldt in the province of New Andalusia, upon the continent of South America. Nor does 
it appear to be uncommon in Jamaica, if we may judge from our having received it from the 
three botanists above mentioned.
