The lowest part of tlie lip is the hypocJdlumi, the upper end 

 the cpichUiuni, and the intermediate portion the mesochilium. 

 AW 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.
