The specimens here figured o f this slender and graceful Fern were gathered by Professor William
Jameson o f Quito, between that city and Esmeraldas, growing abundantly in one spot on the trunk
o f a tree, at an elevation o f 6 000 feet above the level o f the sea. T hese specimens are so much
larger than th e generality o f th o se we have received from Jamaica, that we were at first disposed to
consider them d is tin c t: but a more careful examination satisfied us that the differences are only
owing to a greater luxuriance o f growth, such as are occasionally observed even in Jamaica.
The Tr. meifolium o f Bory, from th e Isle o f Bourbon, differs in its rigid segments and setose
rachis.
