A genus belonging to the small order of Bromelia, -or 
Pine-Apple tribe; and differing from Pircarrnta, in having 
a completely superior germen: Its numerous species are 
parasitic, growing upon the bare trunks and branches of — 
trees, sometimes on the naked face of rocks. A fact which 
may serve to diminish the wonder of their vegetating for 
years when suspended elsewhere by a thread, and which 
has procured them the name of Air-plants, also applied to 
some Orchideous vegetables gifted with the same property.
