The lowest part of the lip is the hypochilium, the upper end 
the epichilium, and the intermediate portion the mesochilium. 
All these parts are, however, nothing more than divisions 
in a very fleshy lip, produced by contractions of its sides, 
and by the lobes, so common in the order, variously arranged 
and combined. 
The species is at once known by the narrowness and 
length of the hypochilium, independently of all other cir- 
cumstances. 
It is said to be a native of Brazil; but we suspect some 
mistake in this statement. It is certainly wild in Mexico, 
for it exists among Count Karwinski’s plants in the Royal 
Munich Herbarium.
