The genus Dilochia has heretofore been unknown from the 

 Philippines. Dilochia Elmeri resembles Dilochia Cantleyi {Hook. 

 /.) Ridl., although it is larger in all its parts. It also is similar 

 to Dilochia Wallichii Bl. from which it differs mainly in the 

 number of the carinae on the disc of the labellum.
