The specimens here figured of this slender and graceful Fern were gathered by Professor William 
Jameson of Quito, between that city and Esmeraldas, growing abundantly in one spot on the trunk 
of a tree, at an elevation of 6000 feet above the level of the sea. These specimens are so much 
larger than the generality of those we have received from Jamaica, that we were at first disposed to 
consider them distinct : but a more careful examination satisfied us that the differences are only 
owing to a greater luxuriance of growth, such as are occasionally observed even in Jamaica. 
The Zr. meifolium of Bory, from the Isle of Bourbon, differs in its rigid segments and setose 
rachis.
