The present species approaches to Cheirostylis, Zeuxine OdontochUus and 

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

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

 Odentoehilus in the kteral arms of 

 the columns, and from Ancectochilus 

 by not having distinct spurs. As the 

 specimen is wanting pollinia, it is 

 quite uncertain as to its proper genus.
