The form of the labellum suggests Eria longicruris Leavitt, 

 a species with which E. maquilingensis is allied. The color of the 

 flowers is not referred to by the collector. From dried specimens 

 the labellum appears to have been tinged with purple when fresh. 

 The calli on the labellum are three in number, the lateral ones 

 carinate and much longer than the middle one, which is basal 

 and fleshy, somewhat lanceolate in outline.
