These amazing orchids resemble a flying duck. The head (labellum) is hinged to the column by an elongated claw. When an insect makes contact with the labellum it snaps shut forcing the insect to exit the flower by rubbing against the column and thereby covering it with pollen.
This orchid likes shady locations next to large granite rocks. The flowering plants do not have a rosette of leaves. Those not flowering grow close to each other covering large areas of ground with their rosettes of leaves. I didn't think to take a photo of the rosettes. :((Photos: Jean
