This species belongs to Schlechter's section Herpetlwrldzis. From 

 M. distans Schltr. and M. megalaidha Schltr., it differs in the form of the 

 lip, especially in the very short auricles and the shortly dentate mid-lobe. 

 The flowers are as large as those of M. meffalantlia, but the mid-lobe is 

 conspicuously produced. 



The colour of the flowers is described as green ; in the dried plant the 

 lip is dark sepia.
