One specimen alone of this plant exists in the Herbarium, and this in a sufficiently perfect state to ex- 
hibit a labeUum of a very remarkable character, sufficient, we believe, to authorize us in constituting of 
it a genus distinct from any hitherto described. It covers, in consequence of its pecuhar shape and size, a 
considerable portion of the perianth, being extended above into two erect wings, while below it is broad and 
fimbriated at the extremity.
