Easily distinguished by the extremely small flowers 
and almost globular spur. I can see no differences in speci- 
mens throughout the above extensive range and can find 
no support for Schlechter’s separation of the Madagascar 
species from that of the mainland nor for his suggestion 
that several allied species may occur on the mainland. 
During his later researches Schlechter seems to have 
adopted the view that orchids must, épso facto, have lim- 
ited distributions and interpreted his species accordingly.
