Hab. Common throughout the West Indies and tropical America, frequently 

 growing pendulous from Palm stems : Amazon, Spruce, n. 2308, and Para, n. o2 

 (;} feet long, including the petiole, and costate almost to the apex). — The species 

 is most variable in point in the length of the stipes, and in the length and dis- 

 tinctness of the costa, but in all other respects very uniform in characters. Mr. 

 Spruce remarks, " when recent the fronds are rather fleshy, and the midrib lieing 

 winged at the back, they appear to have a trialate stipes." 



* ]\Ir. Moore has entered this under Anetium as a distinct species, and has 

 taken the name (not without acknowledgment) from my private herbarium, but 

 without careful examination or any description.
