differently shaped viscidium, and from M. dolichorrhiza 
(Schlitr.) Summerh. by the absence of the two plate-like 
calli in front of the spur mouth, the narrower, tapering 
spur and the widened upper ends of the branches of the 
stipes.

I have not seen this species which is evidently allied to 
M. caespitosa (Rolfe) Summerh. but has larger flowers 
(the dorsal sepal is nearly twice as long). Untortunately 
the floral details are not described sufficiently to place 
the species more accurately.
