Ornithidium simulans and O.vestitum in the past were 
thought to be separable— O. simulans confined to Central 
America; O. vestitum widespread in the West Indies and 
northern South America. However, a comparison of 
these two concepts shows that they are identical. 
This species has been found in Guatemala, Honduras, 
throughout the West Indies and northern South Amer- 
ica where it is epiphytic on trees and on rocks in forests 
at low elevations.
