This species seems to be closely allied to M. pachy- 
stemma Summerh., but the rostellum lobes are linear- 
subulate, the viscidium broadened and obtuse in front, 
and in other respects the description differs from that of 
M. pachystemma.

Easily distinguished by the verrucose roots. The lip 
lamina is narrower than in MZ. pachystemma Summerh., 
the rostellum lobes are more acute and the viscidium is 
shorter and broader.
