Ornithidium neglectum Schlechter in Fedde Repert.

From the evidence of analytical drawings of the 
types of these species supplemented by the descriptions,

are described as white with golden-yellow lip. The only 
other notable discrepancy appears to be in the callus and 
mid-lobe of the lip, a discrepancy which seems negligible 
in view of the many specimens of O. anceps we have 
examined,
