It is quite unusual. When the buds were about go into bloom, I couldn't make out where the spur and where the dorsal sepal were.
The curved protrusion on top of the flower is the spur. It is not a typical looking spur. Don't know what kind of pollinator could perform such a feat of getting to the nectary. I'm thinking it might be bat pollinated, not sure.
It is closely allied to Comparettia and Scelochilus.
