In this section the structure of the nower is nearly that of Encyclium, but the flowers 

 grow out of a grcat spathe , as in Spathium, and thc pseudobulbs are evidently assu- 

 ming ihe condition of an ordinary stem. In E. aurantiacum the calli or linear plates 

 so common in the genus are replaced by three raised lines , the ovary has a very long 

 cuniculus , and the Howers have the regularity of the Hexisean Isochiles.
