From the Royal Gardens of Kew, where it was lately received, 
through Mr. Wilson, from Jamaica, gathered in moist woods, 
Westmoreland County. Sloane gives the Orange River and Rio 
d’Oro, in the middle of the island, as the locality: we possess 
specimens also from Dr. Macfadyen; but it does not appear to 
be an abundant species, or it is much overlooked by collectors. 
Plumier gives only one station for it in St. Domingo, viz. “un 
endroit que les Boucaniers de I’Isle appellent /e fond ¢pineuz, en 
venant des Anses & Pitre au quartier de Leogane.” I have also 
a solitary specimen gathered near Rio Janeiro by the late Lady 
Calcott. Mr. J. Smith possesses a specimen, gathered by Linden 
in the island of Cuba. It is a very distinct and well-marked 
species, reminding one in the size and composition of the frond, 
in the larger and longer fertile fronds, and in the contracted 
JULY IsT, 1856.
