 Dendrobiuvi candoonense, among Philippine species, is most 

 closely allied to D. pseudoconveocum Ames from which it is sep- 

 arated by its oblong linear leaves, three carinae on the disc in- 

 stead of two, and by the smaller lateral lobes of the labellum 

 which are not porrect as in Z). pseudoconveocum.
