Eria microchila is closely allied to E. philippinenm Ames, but 

 is distinct from it in the smaller flowers. From E. Hutchin- 

 soniana Leavitt it is in part separated by the different foliage 

 and bicallose lip. 



In young flowers of E. microchila the lip is distinctly bicallose 



near the base, close to the margin, and supplementary calli maybe 



detected near the middle nerve in front of the claw. It would seem 



that these calli are evanescent, as in older flowers they are wanting.
