Vandopsis leytensis is readily distinguishable from Vandopsis 



Lissochiloides Pfltz. by the very different labellum and shorter 



leaves. The labellum is concave at base and is divisible into hy- 



pochile and epichile. The epichile is made up of the middle and 



lateral lobes, the lateral lobes spreading at right angles, or nearly 



so, to the middle lobe. The hypochile is densely pubescent along 



the median line. Directly in front of the hypochile the lateral lobes 



are situated.
