The plants of all three species, O. maculata, O. monophylla, and O. 
Mackenii are very similar in appearance. Yet the proportions of the 
lip in all are sufficiently distinct to allow easy recognition. The lip 
of O. monophylla always has a distinct elongate isthmus.

This variety differs from the typical form in having winged cap- 
sules. It is possible that when more material is at hand, especially 
fresh flowers, this variety may prove torepresent a species sufficiently 
distinct from O. maculata. There is also a certain difference in the 
outline of the lip.
