Coelogyne Elmeri from the material at hand, clarified by field 

 notes of Mr. Elmer, appears to be a near ally of C. tumida J. J. 

 Sm. from which it is clearly distinguishable by the foregoing 

 description. The general habit and the details of the flower 

 indicate § Longifoliae. The elongated, somewhat fusiform pseudo- 

 bulbs 4 — 10 cm. distant on the stout rhizome and the successional 

 opening of the flowers suffice to differentiate C. Elmeri from all 

 other species of the genus heretofore ascribed to the Philippine 

 Islands. The labellum is 3-lobeJ, pandurate, the basal lobes 

 rounded, constituting a suborbicular base from which the roundish 

 middle lobe is separated by a short isthmus. At the base the lip 

 is broader than at the tip.
