There are not any very near allies of this species. In dried 

 specimens the flowers and the veins of the leaves are orange- 

 yellow. The leaves are prominently three-veined, the lateral 

 veins being close to the margin. In general appearance it sug- 

 gests A coridiu7}imicrochilum (Schltr.) Ames, but is larger in all 

 of its parts and is clearly distinguished by the lateral origin of 

 the flower shoots. The labellum recalls that oi A.philippinense 

 Ames, but is readily separated from it by the elongated lateral 

 lobes of the labellum which exceed the middle lobe in length.
