ORCHIDACEiE 



ippine Islands. The structure of the labellum sets it clearly apart 

 from all other members of the genus. The lip is subsaccate at the 

 base and produced into a long semitubular hypochil which is ter- 

 minated by a transversely elliptical plate or epichil. On either side 

 of the hypochil, near the margin, a thickened keel extends from 

 the base of the lip and terminates in a distinct callus. The terminal 

 plate is tricarinate, the middle carina being longer than its com- 

 panions and reaching nearly to the tip of the lip. Where the hypo- 

 chil joins the column there is a tiny triangular lobe on each side.

This species has recently been collected in Guatemala. I do not 



find any record of this plant, heretofore published, that brings it 



within the Central American flora.
