It differs from the insufficiently described M. peduellaris in the inflor- 

 escence showing a distinct naked portion at the base, in the pedicels which 

 have 3-4 times the length of the sepals, and in the teeth of the lip ; from 

 M. pectinata by the more numerous and smaller leaves, smaller flowers, 

 longer auricles of the lip, etc.; and from M. wariarta by the more numerous 

 smaller leaves, the differently coloured flowers, longer auricles to the lip, etc. 



The leaves appear to have been coloured. 



The flowers are said to be purple.
