Oberonia lipensis is allied to O. henguetensis Ames which has 

 a very different labellum, the terminal lobes being very short. 

 It is also allied to O. minima Ames, which is a much smaller spe- 

 cies with acute lobes at the tip of the labellum. In habit not un- 

 like O. linearifolia Ames and O. neglecta Schltr., but with a very 

 different labellum. 



The base of the labellum is distinctly cordate, the rounded 



basal lobes or rather auricles directed backward. In front of the 



column the lamina of the lip is deeply concave or subsaccate, 



at the middle it is constricted and terminates in two divergent 



quadrangular lobes which are truncate at the tip.
