The present species approaches to Chtirostylis, Zcuxine Odontochilus and 

 Anoectochilus, but is not referable to neither. The new orchid is different 

 from Chcirostylis in having distinct sepals and petals, from Zeuxine and 

 Odentochilus in the lateral arms of 

 the columns, and from Anccctochilus 

 by not having distinct spurs. As the 

 specimen is wanting pollinia, it is 

 quite uncertain as to its proper genus.
