One specimen alone of this plant exists in the Herbarium, and this in a sufficiently perfect state to ex- 

 hibit a labellum of a very remarkable character, sufficient, we believe, to authorize us in const.tutn^ ol 

 it a genus distinct from any hitherto described. It covers, in consequence of its peculiar shape ami m/c, t 

 considerable portion of the perianth, being extended above into two erect wings, whde below it is broad and 

 fimbriated at the extremity.
