to three inches long, elongate-subulate from a narrowly 
lanceolate base, the lateral shortly spreading and then 
pendulous. Petals like the sepals, but shorter and more 
slender, pendulous. Lip quadrate, with rounded angles, 
an inch broad and rather less in length, sides reflexed, 
anterior margin suddenly contracted in the middle into 
a subulate at length filiform recurved tail an inch long ;
