Species about 80, in Trop. Asia, America and Africa—The above 
characters apply only to the section Nervilea, to which all the 
Old World species of Pogonia belong, and which differ by flowering 
before the leaves appear. All the other species, except one in 
Japan, are found in the New World, and their flowering stems 
bear leaves,

than ovary, deflexed ; lip slightly saccate 
at the base . . 1. P. GamMMrgana.
