A. benguetensis and A. Elmeri Ames are very nearly related 

 species. From the material at hand the chief distinctions appear 

 to be in the larger leaves and smooth capsules of A. benguetensis, 

 and in the apical portion of the labellum which in A. Elmeri is 

 div9,ricately bilobed while in A. benguetensis it forms an oblong 

 plate which lies at right angles to the saccate base.
