It IS singular that this very str iking species o f Fern should so lo n g have remained unnoticed iu
the much frequented island o f Jamaica; and have been first brought to the k n owled ge o f botanists
by Humboldt in the province o f N ew Andalusia, upon the continent o f South America. N o r docs
It appear to be uncommon in Jamaica, if we may ju d ge from our having received it from the
three botanists above mentioned.
